Insulation soft roll. Features of rolled heat-insulating materials. Roof insulation roll

The widely used heat-insulating plates have been replaced by rolled heaters, which are more convenient and improved in functionality. Such products are suitable for finishing roofs, walls, utilities, ventilation shafts and other surfaces of complex shape. Rolled insulation has improved technical performance in comparison with mineral wool in slabs, it is characterized by increased density and rigidity.

The flexibility of the insulation will help you in the shortest possible time to complete the work on the insulation of your home

Flexible thermal insulation in rolls

The material has an affordable cost, excellent performance properties. The scope of its application is repair finishing and capital construction, when there is a need to increase the thermal insulation performance of surfaces:

balcony;
basement;
gender;
floors;
attic.

Which insulation keeps heat better:

There are roll-type heaters based on mineral wool, which are glued to the walls directly under the wallpaper. Their main purpose is to increase the temperature inside the room, reducing natural heat loss in the cold season. Additionally, such materials prevent the development of mold and mildew, the formation of high humidity. The uneven surface is perfectly masked due to the soft insulation, which does not require finishing work.

Characteristic features and differences of heaters:

The versatility of rolled thermal insulation based on mineral wool determines the wide scope of its use. . It is indispensable in the modern construction industry., creates a durable working layer of insulation that protects from the cold:

Living spaces;
offices;
warehouses in enterprises;
outbuildings;
baths and saunas.

Insulation, soundproofing walls for wallpaper:

Soft thermal insulation is not damaged by regular contact with ventilation ducts and pipelines. Due to sufficient flexibility, it tightly covers uneven surfaces, and can be laid at sub-zero temperatures.

Material Advantages

Thermal insulation in rolls designed with weaknesses in mind, which characterizes a similar material in slabs. It has a number of positive aspects:

Minimization of thermal conductivity even among models belonging to the budget class.
Large assortment range roll insulation, which are based on different kinds mineral wool. They differ in terms of performance.
No damage by rodents, fungi, microorganisms.

The presence of a large assortment of heaters, will allow you to choose the best for you

Resistance to temperature extremes, adverse weather conditions while maintaining the original thermal insulation performance.
Noise-reducing feature, resulting in increased sound insulation in the equipped room.
Resistance to open fire.
Ease of installation, which even an inexperienced master can handle.

Like other universal materials, soft insulation has a drawback. They are characterized by increased vapor conductivity, which can be eliminated by an additional layer of vapor barrier.

Main types and characteristics

The main component of the described materials is usually mineral wool. It, in turn, is presented in several versions:

Slag. The insulation is made from waste from the metallurgical industry. It differs in strength indicators, while being the cheapest and most affordable product.

Slag wool is one of the cheapest materials that provides good thermal insulation.

Basalt wool. The peculiarity of heaters in rolls for walls and other surfaces is that they are produced using the rock melting technology. Then, thin layers are formed from the resulting content, intertwined into a single carpet.
Glass wool. The heat insulator is created from pre-melted glass cullet. This approach to production process significantly reduces the final price of the described products.

The disadvantage of glass wool is the increased fragility of the fibers that cause itching.

Each of the designated heaters has a specific set of characteristics. But in any case, they all represent an improved version of the standard mineral wool. For example, glass wool exhibits excellent resistance to high temperatures: a heat insulator made from it can withstand up to +400°C. Exceeding this mark entails the complete destruction of the material with the impossibility of recovery.

Which heater is better:

As for the most high performance in terms of thermal conductivity and density, they are typical for a rolled insulation made of glass wool. It tolerates vibration manifestations well, does not smolder and does not burn, absorbs sound vibrations.

There is no shrinkage of such material throughout the entire operational period.

Of the unpleasant moments, there is irritation of human skin upon contact with fiberglass wool, slight instability to moisture.

The presence of the pros and cons of each of the materials will help you choose the best material for: home, cottage, bath

Thermal insulation rolls made of basalt wool also withstand high temperatures, are distinguished by sufficient density and thermal conductivity. Excellent resistance to high humidity. Even when completely wet, the original quality indicators are preserved. Such material is completely environmentally friendly, does not cause irritation upon direct contact, does not cause allergic reactions.

The heat insulator made of slag wool can withstand a temperature load not exceeding +300°C. Otherwise, the slag melts, the structure of the described building product is completely destroyed.

Rolled heat insulating materials differ in parameters, functionality. It all depends on the brand of products, the manufacturer, the requirements of the buyer in the manufacture of the product to order.

The role of the foil surface

The main feature of such insulation devices is the presence of a thin but durable foil coating. In this way, the material is protected from the negative effects of ultraviolet rays and high humidity, which is very important when equipping industrial premises, kitchens, bathrooms, baths, saunas.

Foil insulation tolerates high temperatures well

Laying foil insulation is carried out in accordance with a special technological process. between insulation and finishing material a gap of 1-1.5 cm is necessarily created. This is very important, because at elevated temperatures the insulation maintains a given degree by transferring it to the back wall and then returning it back to the walls, but not to the room.

In comparison with roll materials made of slag wool, glass wool and basalt base, the foil product must be fixed on the crate. The layers are overlapped, the places of their joints are carefully treated with insulation.

When choosing a material, consult with a specialist, he will help you choose the best material

Before buying soft thermal insulation for finishing a room for any purpose, you need to take into account some tips shared by experts. The features and type of the surface to be treated are important, which can be brick, concrete, wood, etc. An aspect such as the thickness of the base should not be overlooked when it comes to external insulation. In this case, the frequency and intensity of precipitation plays an important role., temperature regime by seasons.

A rolled heat insulator made on the basis of any type of mineral wool must be sold in undamaged packaging. Otherwise, moisture accumulates inside the material, worsening the quality of the product. When choosing the described material, its main functionality and purpose are taken into account.

Heaters in rolls - a demanded finishing product. They are easy to use, improve the thermal insulation of rooms. for various purposes keeping it at the right level for many years.

Knauf heater:

During construction or repair, walls, ceilings, floors and other surfaces are covered with special materials, to prevent heat leakage during the cold period and did not bother the heat in the summer season. One of them is roll insulation, often used for large areas.

Advantages of roll material

This material has many advantages. The main thing is that the insulation in rolls does a good job of preserving optimal temperatures indoors. There are other advantages:

The main types of insulation

Thermal insulation in twisted rolls can be used for both external and internal laying. There are options specially designed for pipes and communications. Rolled wall insulation is also available for sale directly under the wallpaper.

Raw materials for their production are also used differently. Thermal insulation from mineral components is the most common. Foamed polyethylene is also popular. Natural heaters like corks are less common and used. Some types have an additional layer in the form of foil or paper. Let's consider each option in more detail.

Special coating for thermal insulation

To improve the characteristics of their products, firms that produce rolled thermal insulation add certain coatings. The basis under them can be different.

Types of mineral wool in rolls

In this group of heaters there are several varieties. Their structure is the same, they differ in composition.

Any type of wool must be covered with a vapor barrier, especially in rooms with high humidity. And it also holds back the smallest particles of fibers that appear over time, negatively affecting a person. As part of the raw materials, formaldehydes are often used, which also affects health. Quality rolls should have a minimum of this substance

For laying mineral wool be sure to install the frame. On the walls, the panels with which it is held are pressed strongly so that the canvas does not move out over time. For the necessary protection from the cold, the number of layers can be increased.

Manufacturers often separate their product according to the purpose of the insulation. For ceilings and ceilings, the rolls will be lightened. For the main floor, walls, and other surfaces, the density of the material is usually increased. Due to this, the dimensions of the roll also change:

length from 3 to 8 meters;
thickness in 3 versions (50 mm, 100 mm, 150 mm);
width from 0.6 m to 1.22 m.

Insulating wool manufacturers

Hardware stores offer wide choose mineral wool. Consider the features of the materials of some companies specializing in this area:

Has many positive qualities. It is obtained by filling heated polyethylene with gases. As a result, a mass is formed with many closed bubbles inside, which subsequently solidifies. For special strength, it is also “crosslinked”, i.e., the bonds of molecules are strengthened by chemical means.

Therefore, there are for sale two options: stitched and, respectively, not stitched. Both types have very low thermal conductivity, but the first one still has the best performance, therefore it is more expensive (its density is 30 kg / m³). The general properties of materials are as follows:

The difference is that cross-linked polyethylene foam is able to absorb sounds well, but its fellow cannot boast of this. As a sound insulator, it works worse. Under mechanical action, the uncrosslinked version loses its shape irreversibly. The stitched one has a high compressive strength, which means it can be used for insulating horizontal surfaces.

Due to the thinness of the material, the length of the rolls can be up to 30 meters, the width is from 0.6 to 1.2 m. The thickness reaches 1 cm. . To fix the material on the wall, special glue is required.

Polyethylene foam brand Penofol

Insulation Penofol - appeared recently, but has already stood out among its own kind. It does not collapse from weather conditions and hostile environment. Heat insulators of this company have several varieties:

foil coating can be fixed on one or both sides;
rolls with an adhesive layer (simplifies installation even more);
specialized type of isolation for communication networks;
insulation for harsh conditions with a thickness of up to 40 mm.

Combined technology allows you to further reduce the thermal conductivity of insulated surfaces. Moisture-resistant and durable material that does not require vapor barrier costs can be used in various directions. Does not lose its properties in the temperature range from -60 to +100 С°.

Cork insulation for surfaces

An environmentally friendly and durable raw material for the production of thermal insulation is cork oak bark. Absolutely natural ingredients make the rolls safe for health. The crushed bark is connected with organic glue and pressed. The thickness ranges from 2 to 6 millimeters. The length of the roll reaches 10 meters, the width is mostly meter. Most often, in this form, the cork goes under the wallpaper, on the substrate for the laminate or "warm floor".

Thermal conductivity index not inferior to mineral wool, but the layer is used much thinner. Cork insulation is slightly flammable, poorly absorbs water and delays noise. However, its density is high, respectively, and the weight is large. The margin of safety is high, the service life is declared up to 50 years. The negative side is the price of "naturalness", compared to the rest, it is quite high.

This insulation is produced mainly by Portuguese companies: Wicanders, Izora, Amorim. They offer a wide range of insulation rolls, which can also serve as wall decoration. Installation is also simple, basically the cork is “planted” on glue.

Modern technologies provide a huge selection of heat insulators for any premises and structures. The selection criteria are based on which surface needs to be covered and how much the buyer is willing to pay for it in order to maintain comfort in their home.

Thermal insulation of walls is a task that should be approached with special attention, because the materials for sheathing have different properties and "principle of operation", and on the market it is very often presented that no matter what insulator you take, there will be "Africa" in the room. In fact, this is not at all the case and you need to deal with each proposal in detail so as not to waste money, effort and time in vain.

Now usually use several types of heaters:

in the form of rolls;
rigid polystyrene boards;
dense mats made of mineral wool.

The last two options, in principle, are quite understandable - these are really effective technologies, but also more expensive. But the rolled category of materials is not so unambiguous - this is where you need to figure it out in detail.

First, it is worth considering the main theoretical point.

What are rolled heat insulators

The first type of insulation made in the form of rolls is mineral wool materials. Vata itself happens on this basis:

From cullet and quartz. This is the so-called glass wool, which is so common in Soviet-built houses.
From rocks (for example, basalt);
Cotton wool from blast-furnace waste.

It is recommended to use slag insulation only outside the walls, since there it does not cause any harm to health. But basalt products, in principle, can be laid indoors, the main thing is to pull a vapor barrier on top of them so that small fibers do not get into the air.

As for whether to insulate the walls with basalt wool from the outside or better from the inside, there is also no definite answer. The fact is that the material is afraid of moisture and if you mount it from the side of the facade, then you need to make good external protection (for example, from a vapor barrier and a metal profile). And this is expensive - if there are already such means, then it is better to use polystyrene foam or cotton wool in the form of plates.

But in general, basalt rolled insulation is still more relevant for use from the side of the room, because this way it lasts longer and better. The basic principle of action here is the retention of heat, that is, cotton wool, as it were, does not allow it to quickly go outside.

The second group is thermal insulation made of foamed polyethylene or polypropylene. The material is also produced in the form of rolls and can be of two types:

foil coated;
with metallized outside.

The first insulation is good because it has a good level of resistance to mechanical stress and reflects heat well. Due to this, the solution is suitable for indoor applications, for example, it is possible to mount the curtain behind radiators to retain heat. Among the shortcomings, one can single out poor vapor permeability and the fact that a foil of sufficient thickness will be expensive.

In addition, this thermal insulation is not suitable for direct contact with concrete walls- alkali simply corrodes the foil.

Metallized products pass steam well, but they do not reflect heat efficiently enough. Topically used for wall cladding in shower rooms and rooms with high humidity. By the way, here the coating cannot be called resistant at all - the slightest mechanical impact and the metal begins to “peel off” from the base of the insulation. Now we can move on to the most important question.

So which option is better to choose: cotton wool or polyethylene foam

The main point that is important to understand is that foamed polyethylene or polypropylene in the form of rolls is exactly thermal insulation, that is, a material whose purpose is to slightly improve the characteristics of the walls, and not fully insulate them. Regardless of where it will be fixed - from the inside or from the front.

But basalt wool is already a real insulating layer. True, in the case of indoor use, the wall will still freeze through, just noticeably less heat will come out of the room.

It turns out that from the inside, polypropylene will give a lesser effect than cotton wool, since the temperature will rise only by a degree and a half. And even if you perform outdoor installation, then the “picture” will be the same, but with only one positive moment - the wall will freeze a little less and the condensate from the side of the room will disappear.

At the same time, the material has an undeniable advantage - it is cheap and it is very easy to mount it. It is more difficult and expensive to work with cotton wool, since it will be necessary to make a false wall (usually drywall) to protect the basalt fibers, and besides, it is important to take care that moisture does not get into the structure of the material. If this happens, then the effect of all the work done will be zero, since all thermal insulation qualities will disappear very quickly.

Here it seems to start to seem that cotton wool is better anyway (because it is “warmer”), but everything is decided by the nuances of the situation. Yes, cotton wool seems to be good, but what's the point in it if, for example, you need to insulate the shower room not in the house, but, for example, in the country and you don’t want to invest? The obvious budget solution in this case is a metallized insulator - stick it on the wall and forget it.

But in the case of a more or less capital approach, but again in the absence of significant financial resources, it is better to opt for mineral wool and insulation from the inside. It turns out that there is no ideal option and a decision needs to be made only based on the characteristics of the project.

Rolled insulation is a material with a low thermal conductivity, which is additionally characterized by a sufficiently low rigidity, but at the same time keeps its shape well. Coatings of this type are flexible, which allows you to finish areas of complex configuration. Laying such material is easy. However, it is important to choose the right dimensions. Insulation in rolls is fastened end-to-end, it is unacceptable to leave significant gaps between adjacent sections of thermal insulation. This will lead to the formation of cold bridges.

The material of this type is universal, due to its properties (low stiffness and density, flexibility). This means that it can be used at objects of various purposes (private, economic, public, etc.). However, it should be remembered that each of the types of such material may have limitations for use, for example, if it does not meet the operating conditions. Roll insulation is suitable for installation on horizontal and vertical surfaces. It is thick enough to keep its shape.

A coating with a metallized layer is mounted on objects and surfaces where it is important to provide the highest level of protection against heat loss: in baths, saunas, when installing a water / electric heated floor, etc. The desired effect is achieved due to the presence of a heat-reflecting layer.

Rolled heaters are the only affordable materials that are suitable for protecting surfaces with complex configurations: with differences in levels (stepped), bends, joints, hard-to-reach places. This possibility is due to flexibility and low rigidity.

Directions for the use of this type of thermal insulation:

wall covering inside and out decorative trim any kind (rigid boards, soft materials and even wallpaper);
floor protection, in this case, rolled thermal insulation is protected from deformation by a crate;
flat insulation / pitched roofs;
reduction of heat loss through the ceiling;
protection of pipes for various purposes.

Types of materials in rolls

There are two groups of heaters, characterized by flexibility, low density and rigidity:

Based on expanded polystyrene, polyethylene. Such materials are characterized by a closed-cell structure, which is achieved by foaming the raw material. As a result, most of the volume is a gaseous medium. When foaming polyethylene, a flexible coating of small thickness is obtained. Rolled insulation of this type is characterized by low thermal conductivity, wear resistance, and lasts a long time.
Mineral wool is represented by varieties: glass and slag wool, basalt or stone wool. These are natural insulating coatings characterized by low thermal conductivity. The disadvantages include low strength, a tendency to sag during operation, hygroscopicity. The last of the properties is the reason for the short service life of the coating. This insulation is suitable for walls, floors, floors, attics, basements, roofs. If you provide protection from moisture in areas with increased loads, you can avoid deformation of the coating.

Foamed insulation is divided into types, taking into account differences in the method of production:

physically stitched;
chemically crosslinked;
gas-foamed.

The first 2 options are characterized by similar properties, but are manufactured using different technologies. In addition, heaters are divided into types, taking into account differences in structure: foamed with additives (flame retardants), foil. The last of the options has improved properties. It not only allows you to reduce heat loss, but also reflects heat radiation, returning it back to the room.

glass wool

The basis of the material is glass industry waste, sand. The raw material is exposed to high temperatures (+1450°C). In the process of melting, the finest fibers appear. To obtain a heat-insulating material, a binder is added, through which the fiberglass is glued together. Then molding takes place. In order for the binder to obtain the desired properties, it must undergo a polymerization process. At the last stage, the material acquires a yellowish tint as a result of staining.

A heat-insulating layer of this type protects different types of objects. Glass wool is a versatile coating option. However, when working with it, you need to use personal protective equipment (respirator, goggles, gloves, closed clothing). This is due to the fact that the insulation contains particles that are characterized by a small mass and can be released into environment under the influence of external factors. Dust enters the respiratory tract, settles on the skin, mucous membranes, which provokes tissue irritation.

In order to somewhat improve the strength indicators, the rolled material is reinforced. The disadvantages, in addition to the release of abrasive particles, include a relatively low thermal conductivity. According to this parameter, the insulation loses to foamed counterparts. Another disadvantage is hygroscopicity. The vast majority of mineral coatings strongly absorb moisture.

Advantages of glass wool:

good soundproofing properties;
sufficient level of strength;
the material is lightweight, which means it will not weigh down the structure;
installation does not require special skills;
flexibility;
vapor permeability;
fire safety;
elasticity, due to which the insulation can restore its original shape;
small width, which means that glass wool will not hide space;
resistance to the formation of mold, fungi;
insulation is unattractive to rodents.

When choosing, not only positive / negative qualities are taken into account, but also coating parameters. Glass wool is characterized by the following properties:

the value of thermal conductivity is in the range of 0.039-0.047 W / (m * K);
water absorption coefficient of glass wool with incomplete immersion - 15%;
this type of insulation is operated at a temperature of -60 ... + 250 ° С;
upon contact with water during the first day, the coating will absorb water in the amount of 1.7% of the total volume of the heat-insulating material;
sound absorption index: from 35 to 40 dB.

In terms of thermal conductivity, glass wool is similar to such heaters: mineral wool, expanded polystyrene.

Izolon

This is a foamed polyethylene foam, which is characterized by a closed-cell structure. It is offered in the following varieties: plain, with a foil layer on one or both sides. Izolon is a fairly dense, but at the same time soft insulation. Its characteristics:

the average thermal conductivity is 31 W / (m * K);
density - 33 g / m³, with a decrease in the value of this parameter, thermal conductivity increases;
the water absorption coefficient is 1%, which indicates the absence of the tendency of the insulation to absorb moisture;
the material does not pass steam;
the ability to perform its main task (reducing the intensity of heat outflow) at low temperatures - up to -60 ° C, while the insulation does not lose its properties, does not break, does not deform;
the duration of operation is about 100 years;
there is resistance to negative factors: precipitation, high loads;
when burning, toxic substances are not released;
the material is environmentally friendly;
insulation isolon protects the object from noise, and a decrease in the intensity of sound waves is noted even with a minimum thickness of the material.

If we consider the foil coating, then we should highlight its ability to reflect heat. The insulation reflects 97% of the heat back into the room. Isolon is not deformable. This means that under the influence of moderate loads, it retains its properties.

Slabs in rolls

In this case, we are talking about materials with increased rigidity, which are formed into rolls. These include basalt wool. This material is characterized by a fibrous structure, superior to glass wool in terms of hygroscopicity, thermal conductivity. In addition, basalt wool in rolls is almost the same density as isolon (30 kg / m³). The thermal conductivity of the material is 0.039 W / (m * K). In terms of water absorption coefficient, the insulation is inferior to foamed analogues (15%). The main advantage of such a coating is non-combustion.

Roll Size Chart

For comparison, insulation is taken, the thickness of which does not exceed 50 mm. This is due to the fact that more massive rolled thermal insulation materials roll up much worse. Fibrous coatings are included in the review. Manufacturers of insulation in rolls:

To compare coverages by cost and determine the best suitable option, take into account the number of strips in the package.

conclusions

Rolled thermal insulation is in many cases preferable, because it is characterized by flexibility. In addition, the material of this group is characterized by low thermal conductivity, which allows it to be used for the purpose of warming an object. However, it should be borne in mind that fibrous roll coatings do not tolerate contact with liquid, so you need to carefully protect them with waterproofing.

If you plan to use foamed insulation, it is important to remember that they do not let steam through, which means that the indoor climate may worsen. To avoid negative consequences during the installation of heaters of this type, it is recommended to install supply and exhaust ventilation or improve the efficiency of natural air circulation in the room.

How do you look at the prospect of reducing home heating costs by almost a third? We think this is the case when comments are unnecessary. To achieve such a result is real, it is enough just to choose the right thermal insulation for the roof.

One of the most common thermal insulation materials mineral wool is considered, in particular, in the form of mats. However, when it is necessary to insulate, for example, large areas, such a solution is ineffective. For such cases, roll insulation will do more.

All materials of this type have approximately the same advantages, which explains their high demand. These are qualities such as

low thermal conductivity
good soundproofing,
optimal hygroscopicity,
high water repellency,
chemical resistance,
fire safety.

And this is not the whole list.

Roll insulation, due to its elasticity and flexibility, easily restores its shape, suitable for work on uneven surfaces. It does not have any temperature restrictions, as it retains its performance characteristics at extreme temperatures.

Scope of insulation in rolls

It is successfully used for roofs and basements, floors and ceilings, pipes and more. The device of thermal insulation from this material is a fairly simple process. Moreover, the work can be done independently, without the involvement of additional labor. Therefore, this type of thermal insulation has gained great popularity in private construction, in particular, baths, outbuildings, etc.

Types of insulation

In a separate group, materials with a protective layer of foil are distinguished. At a cost, they are somewhat more expensive than the others, but at the same time they have many additional valuable properties.

The foil itself does not have the thermal conductivity necessary for the insulation, however, it effectively retains heat due to the ability of the reflective surface to block infrared rays from the room. It is worth noting that at the same time it does not allow their penetration from the outside. The last one is pretty useful quality for roofing insulation, especially in hot summers, when the roof gets very hot under the influence of sunlight.

Insulation roll foil allows you to provide the maximum length of the material, that is, it is laid from one whole strip, which is extremely important for its effectiveness. . These include foamed rubber, polyethylene and other rolled materials.

These materials do not hold their shape and are easily rolled into rolls. They are quite efficient and easy to work with. Unlike foil insulation, they are used in combination with vapor barrier, which creates the perfect tandem against the cold.

These include foamed rubber, polyethylene and other rolled materials. These materials do not hold their shape and are easily rolled into rolls. They are quite efficient and easy to work with. Unlike foil insulation, they are used in combination with vapor barrier, which creates the perfect tandem against the cold.

This is the most common type of isolation. This form of packaging is considered by many to be optimal, since with this approach, long strips of insulator take up a small volume. Most often, floor beams or mounting profiles are installed in increments equal to the width of the roll. This greatly simplifies installation: firstly, the materials are simply spread over the surface and fixed, and secondly, no extra seams are formed.

Overview of manufacturers: Izover, Knauf, Ursa

How to choose the right roof insulation How to choose a roll insulation. Varieties of roll insulation. What are the advantages of rolled foil insulation. Roll characteristics

Popular manufacturers

There are products from various manufacturers on the market. Each brand has its own features and benefits.

Knauf

The German manufacturer offers a material that does not contain formaldehyde. Knauf products are safe for people. Mineral wool does not cause allergies, but it should be laid with gloves. The microscopic fragments that make up the insulation can cause skin irritation.

Roll materials Knauf are not interested in insects and rodents. In addition, they are able to protect against external noise due to good soundproofing characteristics. They are characterized by low thermal conductivity and good air permeability. The company offers materials for the protection of walls, slabs, pipes and other surfaces in cottages and country houses.

Isover

A heater that is different high density. The French manufacturer offers products of various thicknesses: from 20 to 150 mm, which significantly expands the possible area of \u200b\u200buse of Isover insulation.

The company's catalog contains heat-insulating material with foil, which is often used to insulate pitched roofs, walls, ceilings, and install underfloor heating not only in houses, but also in baths and saunas. In terms of flammability, it corresponds to the first class.

ursa

High-quality professional insulation with a long service life. It has excellent soundproofing characteristics. Does not burn. Under the influence of a flame does not emit toxic substances. During installation, it does not break, does not crumble. Pleasant to the touch.

When insulating the walls of private houses, M-11 is most often used. When performing thermal insulation work in the industrial complex, preference is given to P-30.

Topizol

The insulation can have a thickness of 3 - 20 mm. Suitable for various climatic zones, including regions with high humidity. Doesn't rot. Differs in good vapor permeability. With sufficient tightness of the seams, it is able to withstand gusts of wind.

The thickness of the foil at Penofol is 12 - 30 microns with a base thickness of 2 - 10 mm. For insulation of surfaces operating in fairly harsh conditions, material up to 40 mm thick can be used.

Eco-friendly, safe, suitable for warming children's rooms.

Scope of roll insulation

Rolled heaters are used for thermal insulation of vertical and horizontal surfaces. Foil material is indispensable for creating thermal insulation in bath rooms, because it retains heat well and has heat-reflecting properties. And also this material has found wide application for thermal insulation of individual structures, joints, in hard-to-reach places.

Consider the main ways to use rolled heat insulators.

Rolled heat insulator for walls

Roll insulation for walls can be used as a heat-insulating material applied under decorative finishes, including wallpaper.

The application technology is very simple:

self-adhesive material is glued to a wall prepared in advance, leveled and cleaned of debris and old finishes;
a cement-based adhesive is applied to the heat insulator layer, resembling liquid plaster in properties;
after the adhesive has hardened, you can start gluing the wallpaper.

The use of such material under the wallpaper will significantly increase the heat-preserving properties of the walls, as well as their sound insulation.

Roll heat insulator for the floor

It is used as a substrate for various types of decorative floor coverings. It has not only heat-insulating properties, but also gives the floor "softness", eliminates squeaks and sounds during shrinkage and movement of the floor covering.

In some cases, a foil heat insulator can be used to insulate the floor, this will increase heat retention, however, the cost of materials reinforced with foil is 30-60% more expensive.

The technology for the production of floor insulation using foamed polymer in rolls is very simple:

the material is glued to a wooden floor or concrete screed using an adhesive composition or self-adhesive properties;
leveled so that there were no "bubbles";
the floor covering is laid on top.

The advantages of such a heat insulator include ease of installation, no debris, durability and environmental safety. When choosing a rolled heat insulator for the floor, it is worth remembering that the “softer” the floor covering, the denser the insulation should be.

In other words, it is better to use a polymer with maximum density under linoleum, otherwise, when walking, you will “drown” in flooring, but under a laminate or parquet, you can lay a polymer with any density.

Roof insulation roll

Suitable for thermal insulation of pitched and flat roofs. A roof insulated with such material will be warm for several decades. You can lay thermal insulation on your own, without involving highly paid specialists. The heat insulator is located between the elements truss system roofs, while distortions, the formation of waves and other defects are not allowed.

In some cases, for example, when insulating a residential attic room or in regions with a cold climate, it is recommended to lay the insulation polymer in two layers.

The technology of work on the installation of thermal insulation of the roof depends on design features. Best Option when thermal insulation is calculated at the design stage. In this case, the work boils down to the fact that the rolled material is rolled out and glued to the inner surface of the roof, a layer of vapor barrier material is laid on top and the final finish is arranged, for example, siding, lining, etc.

Application of rolled insulation

This technology is far from perfect and creates only the illusion of real savings in material resources, since in fact this type of insulation is inferior in all respects to such sprayed counterparts as polyurea

Another difficulty is the application technology. It should be mentioned right away that all surfaces must be prepared: thoroughly cleaned or even washed. Even minor contamination can lead to negative consequences. Self-adhesive insulation is applied similar to adhesive tape, but the effectiveness of this method is lower. Over time, the adhesive loses its properties, especially under the influence of temperature changes, and the material peels off. Fused insulation is applied using gas burner. It's a slow and painstaking process, but the grip is somewhat better, though there's no guarantee it won't slack in some places.

Regardless of whether roll waterproofing of the floor or any other surfaces will be carried out, this process takes a lot of time and effort. Accordingly, the term for putting the object into operation is delayed. And yes, this work is expensive. Therefore, this technology is far from perfect and creates only the illusion of real savings in material resources, since in fact this type of insulation is inferior in all respects to such sprayed counterparts as polyurea.

Advantages and disadvantages

The main advantages of roll material are:

Versatility. Suitable for thermal insulation of any surfaces. For complex spatial shapes, including curvilinear, a suitable piece can be cut.
Minimum requirements for surface preparation prior to laying.
Benefit in terms of material price and work productivity when insulating large wall areas, especially straight sections.

They have rolled materials and disadvantages.

High labor intensity when laying in a frequent crate, additional time is required for cutting.
Low rigidity does not allow them to be used where it is required to withstand significant loads.

In general, the advantages compensate for the disadvantages, which explains the high popularity of roll materials among consumers.

Materials are harmless to health, provided they are used correctly and fire-fighting regime is observed.

Varieties of roll insulation

Mineral wool

Available in several modifications. A common disadvantage is hygroscopicity. All heaters must be protected from direct contact with liquids; the difference between them is only in the intensity of its absorption.

Glass wool. Pros: one of the cheapest (made from glass "battle" that has been remelted), unattractive to rodents, insects (often used in the arrangement of warm floors). Increased density, the ability to dampen sounds, non-combustibility add glass wool advantages in use. Minus the complexity of working with the material. When installing a rolled heat insulator based on glass wool, you cannot do without protective equipment. And not only the respiratory organs, vision; tight, closed clothing is needed - microscopic fractions of glass penetrate literally everywhere.
Slag. It is also based on waste, but the metallurgical industry. In terms of cost, this insulation is comparable to glass wool (even somewhat cheaper), but loses in terms of resistance to high temperatures. But in terms of thermal conductivity - the leader among mineral wool. For all other characteristics, it is approximately on the same level with other heaters of this group. Cons: absorbs moisture (increased hygroscopicity), dampens noise poorly.

There is another drawback that makes the use of slag wool for insulation metal pipes impractical. It is not recommended to use it for thermal insulation due to residual acidity - it acts destructively on steel.

Basalt wool. The raw materials are processed rocks. Pros: the ability to withstand high temperatures (up to +700), the optimal combination of thermal conductivity / density characteristics. The peculiarity of the material is that after getting wet it does not lose its heat-insulating properties (although there is a limit to the percentage of humidity), it has a high sound absorption, is fire-resistant, “environmentally friendly” (safe for allergy sufferers).

There are few cons: this insulation needs high-quality vapor barrier, it becomes caked over time.

Any of the listed thermal insulation materials is also sold in the "foil" modification. The thinnest layer of aluminum increases the heat-reflecting properties of the product, protects it from contact with moisture.

Polymers

All roll heat insulators are made on the basis of foamed polyethylene or polypropylene. They differ in characteristics, but given the small thickness of the sheets, the difference in thermal conductivity between them does not really matter, so they can be considered identical. The most advertised, although not the only representatives of this group of elastic heaters on the market: Penofol (PE) and Penotherm (PP).

Russian products under the brands Energoflex, Energofloor, Jermaflex (combined material) from ROLS ISOMARKET are characterized by good reviews. It is relatively new on the market, but judging by the exchange of opinions on the Internet, it has perfectly established itself as an effective and universal insulation. Its quality was also appreciated by specialists.

The main role is assigned to the metallized layer. It is the foil that prevents the passage of heat rays through the material. The heat insulator is covered with it on one or both sides; the choice of option is determined by the conditions of application.

Choosing a heater of an unknown brand, you may encounter a substitution of concepts. To reduce the cost, individual manufacturers instead of a foil layer apply metallized spraying to the thermal insulation. Such a screen does not differ in durability, and in terms of efficiency it is significantly inferior to the aluminum coating.

So which option is better to choose cotton wool or polyethylene foam

The main point that is important to understand is that foamed polyethylene or polypropylene in the form of rolls is exactly thermal insulation, that is, a material whose purpose is to slightly improve the characteristics of the walls, and not fully insulate them. No matter where it will be fixed - from the inside or from the front

But basalt wool is already a real insulating layer. True, in the case of indoor use, the wall will still freeze through, just noticeably less heat will come out of the room.

Manufacturers of heat insulators and their products

The greatest demand from the consumer is used by rolled insulation from several manufacturers.

Knauf is a German brand whose products do not contain formaldehydes, which gives the finished product absolute safety and harmlessness, which is relevant during installation work.

Specifications

For heat-insulating material in rolls, released under various trademarks, common characteristics are characteristic.

Environmental friendliness

The insulation meets the regulatory requirements for environmental safety.

As a rule, it contains salts of heavy metals, alkalis, acids, oxides, phenols or toxic organic compounds that are inactive at room temperature, are present in a minimal amount.

Due to the low chemical activity, thermal insulation practically does not interact with aggressive media, and therefore, for example, is not afraid of solvent exposure.

Biological stability and fire safety

The material has a high level of biological stability. As a result, it does not contain rodents, fungus, mold. For insects and animals as food, it is uninteresting. Depending on the composition and other characteristics, the insulation is able to withstand exposure to high temperatures.

Air and vapor permeability

If the insulation is used to insulate the floor or walls, breathability is an important indicator.

When using rolled materials, you can not be afraid of excessive dampness in the room, the formation of condensate and other negative phenomena, provided that the installation is done correctly.

When going shopping, it is worth remembering the following aspects of the choice:

Suitable for indoor and outdoor use various variations insulation.
The surface that will be covered with rolled thermal insulation also matters. There is a fundamental difference between the materials used to insulate the ceiling and walls. Each of these bases has its own insulation.
It is also important to remember what material the walls are made of. A heat insulator for a wooden base may not be suitable for a concrete base and vice versa.
When choosing the thickness of the material, it is worth taking into account the temperature conditions in the winter and the climate for a particular region.
Before purchasing, it is imperative to familiarize yourself with the quality certificates and other permits for the selected roll insulation, and in addition, make sure that the packaging is intact. Moisture, even in small quantities, can adversely affect the design parameters of the material and its properties.

Choose quality material from trusted manufacturers

Heaters in rolls are presented on the market in a wide range. Each of them has its own characteristics, has positive and negative characteristics. The choice of a particular option is up to the user, but if there are difficulties, you should not rely on chance. It is better to seek help from professionals and save your nerves and money.

3 Roll foil thermal insulation

The rolled foil insulation presented on the market, as a rule, is made either on the basis of polyethylene foam (quite a popular brand "Penofol"), or on the basis of polypropylene ("Penoterm").

These are two materials almost identical to each other, the difference between which is only in physical and mechanical characteristics. If we consider only those that affect the direct efficiency of use as a heat-insulating material, then foil roll insulation for walls based on polypropylene looks more preferable.

So, the polypropylene base has an order of magnitude lower thermal conductivity (a difference of about 30%), less moisture absorption and better resistance to external mechanical influences.

In fact, the last factor can be neglected, since the foil heaters themselves, due to their minimum thickness, do not fulfill effective insulation when the foil is damaged, so it is important to look at the quality of the foil coating. .

Roll foam with one-sided foiling

Unscrupulous manufacturers, in order to reduce the cost of production, can use not aluminum foil as a shielding layer, as required by the technology, but ordinary metal spraying.

The effectiveness of such spraying is much lower than that of foil, while the cost of such products sold under the guise of high-quality insulation is comparable to high-quality products from trusted manufacturers. When choosing foil-covered insulation for walls, floors, or pipes, carefully check the quality of the shielding layer.

High-quality foil thermal insulation has the following advantages:

High heat shielding ratio, about 97%;
Wide functionality - foil materials are used not only for household insulation of walls, floors and ceilings, they are also widely in demand for thermal insulation of all kinds industrial equipment;
Minimum roll weight;
Ease of installation - foil thermal insulation does not require frames, anchoring and similar frills, it sits on the wall on mounting foam or regular construction adhesive;
Minimum cost - the price of foil materials is much lower than that of mineral wool;
Complete vapor barrier;
Safety for the human body.

Foil insulation has only one significant drawback - it is prone to burning. Temperature regime operation of polypropylene - 150 degrees, polyethylene foam - 80 degrees.

3.1 Features of thermal insulation of the balcony with foil roll insulation (video)

Specifications

Roll insulation materials are characterized by the following main parameters:

Environmental friendliness. All models on the market must comply with building safety requirements for installation, operation and disposal. They should contain small amounts of harmful substances, these substances should not be released from the insulation during its storage, installation and during use. The packaging indicates the method of disposal. The materials are resistant to organic solvents and other active substances.
Fire and biosecurity. Mineral insulation does not burn itself and prevents the spread of flame. Foam materials are able to withstand fire for a certain time. Materials prevent mold and repel rodents.

Air and vapor permeability. Key characteristics. They show how much air or water vapor at a certain temperature can seep through a unit area of the material. Vapor permeability is necessary in order to remove excess dampness from the room to the outside through the walls and their ventilation systems.
Strength. An important characteristic of insulation for wallpaper. Touching, including with hard objects, should not damage the wallpaper.

What roll insulation to buy

Roll insulationis the name of a whole class of lightweight thermal insulation widely used in civil and industrial construction. They are made from staple fiberglass with the addition of various binders, fillers, water repellents (substances that repel water), which give them softness, elasticity and resilience. Roll thermal insulation is the most inexpensive of all types of insulation, therefore it is in consistently high demand among builders.

This section of the site presents roll insulation, their price and roll parameters. All information about products from different manufacturers is given on one page. Here you will also find short description each of them.

ROLL INSULATION URSA

This is a very well-known line of heaters from a European manufacturer - the URALITA concern. Roll insulation brand URSA are soft elastic mats made of staple fiberglass. Each brand has its own marking, which allows buyers to easily navigate the characteristics of the material and, accordingly, its purpose. URSA heaters are high-quality lightweight heaters recommended for use in horizontal unloaded building structures. good warmth specifications, ease of transportation and installation make them the most popular for many years.

A special place in the line of rolled heaters of the URSA Concern is occupied by new generation heaters under the URSA PUREONE trademark (in rolls and plates). Acrylic, a neutral and safe polymer, is used here as a binder. The production technology of these heaters eliminates the use of phenols and formaldehydes, which makes them particularly environmentally friendly. They are widely used in Europe, America, Japan for heat and sound insulation indoors. In Russia, they also gained well-deserved popularity.

ROLL INSULATION KNAUF

These are natural mineral wool insulations made on the basis of innovative ECOSE technology. In the manufacturing process, binders based on natural ingredients are used, therefore it has a pleasant color of natural linen, and a texture that is pleasant to the touch. Due to environmental friendliness, such heaters can be used indoors.

You can always contact our specialists who will tell you where you can find additional information about the insulation you are interested in or give advice on how to install the material.

Mounting technology

The installation technology of rolled insulation is slightly different from plates. They begin to insulate the walls or floor initially. The walls are mostly made of slabs, as is the straight ceiling. Therefore, often, the floor and pitched ceiling-walls are suitable for insulation and installation. When insulating the floor, it is worth looking at what type of insulation is available.

Insulation is mainly used in foil, but sometimes insulation rolls are covered with ordinary heat-insulating foil or metal film. The insulation should move away from the walls by 1 cm. This is due to the fact that with temperature changes the material contracts and expands. The lack of free space in a metallized or foil insulation leads to its deformation and damage over time.

Ceiling (pitched) heaters are fixed between the rafters, cutting out a little more to insert better between the boards. Insert them strictly from the bottom up to avoid voids. After installation, the surfaces are clamped with main profiles or boards for applying additional (for example, vapor barrier) materials from above. The work is carried out very carefully.

Let's move on to the installation of walls with a roll type of insulation from the inside. It is produced by preparing the walls for pasting. Dilute a special glue for cotton wool, the wall should not be putty or plaster, only bare concrete or brick is allowed. The composition is applied to the wall evenly under a special comb, after which they start gluing the rolls, which can be cut for convenience.

At the same time, it is desirable to make the wall itself in a level, plane, if there are no further plans for sewing into a box or gluing glass wallpaper. After the material is mounted on the wall, it is necessary to screw it in. Each petal should be slightly recessed in the cotton wool. At least 5 fixing holes are required per 1 m2. It is better to fasten the sheets themselves and the space between them (in this case, both sheets will grab, which will avoid warping, bring out the level and plane).

After the sheets have set, a layer of glue should be applied. The technology resembles puttying, only with a different solution

It is important to monitor the level and plane. It is necessary to make at least two passes, since it will be problematic to put a good layer the first time

After leveling, regardless of the type of room, you can proceed to the next work. When installing drywall sheets inside the house, they are fixed with dowels to the thermal insulation layer, which is desirable to be treated with glue, as in the previous paragraph.

About the advantages of URSA roll insulation, see the video below.

Operational Imperfections and Maintenance Difficulties

Each type of waterproofing material has its own unique characteristics. So, technonicol, which, according to the manufacturer, can withstand high mechanical loads, may not withstand increased soil mobility. Therefore, many use a modification for waterproofing road substrates from the same manufacturer. But these are unjustified costs.

With regard to maintenance, for example, in the event of damage to the polyurea coating, it is enough to simply spray a small layer on this place locally. But rolled waterproofing, which has peeled off in some place, requires serious repairs. It is necessary to remove it, at least in this place, prepare the base, apply insulation again, blocking the formed seams. Of course, there is no question of any aesthetics, and the quality of such a patch will be far from perfect.

Waterproofing with roll materials is not universal. So, with their help it is impossible to process surfaces of complex shapes, for example, the bottom of a car. And even roof waterproofing can be a serious problem. In addition, high temperatures adversely affect this material and the degree of its adhesion to the base.

The main disadvantages of waterproofing with roll materials in specific conditions:

Rolled roof waterproofing – the impossibility of processing surfaces of complex shapes, Long procces application, susceptibility to negative effects of temperature changes, complexity of maintenance
Rolled floor waterproofing – poor perception of constant mechanical loads, especially in vibrational conditions
Roll foundation waterproofing – instability to the negative impact of moving soils, additional load on the foundation, which is undesirable in areas with elevated ground water and in loose soil bases

Characteristics of basalt wool

If the insulation under the roll wallpaper, which was discussed above, does not suit you, then you can choose basalt or fiberglass wool, which has a wide application potential. It can be installed on walls or floors, as well as on ceiling spans. It is not recommended to use this material for sloping roofs, this is due to the fact that over time, the massif slides, and the insulation density is broken. If you want to use this floor, then you need to lay at least two layers. This will allow you to get 1 decimeter of thickness. If there is a need to insulate the walls, then half the amount should be used, while laying the material in one layer will be enough. If you want to achieve the arrangement of an effective heat-saving screen, then you should use a similar thermal insulation with vapor and waterproofing.

What to consider when working

Insulation with mineral roll materials can be carried out at any time of the year, it is only important to protect the material from precipitation. . The use of foam materials mounted on an adhesive layer depends on the air temperature

Usually limited to -10C. Special adhesives are also produced, effective up to -20C.

The use of foam materials mounted on an adhesive layer depends on the air temperature. Usually limited to -10C. Special adhesives are also produced, effective up to -20C.

Before the start of insulation, a minimum surface preparation is required:

Dismantle pipes, electrical wiring, lamps, decorations, plants, etc.
Clean the walls from the remnants of old coatings, debris and dust.
Install a crate for mineral insulation.
Level and clean the surface for gluing foamed thermal insulators.

Installation does not require special equipment, from the tools you will need:

construction knife;
stapler;
screwdriver;
hammer;
double sided tape.

It is more convenient to carry out installation and cutting of rolled heaters together, especially with large amounts of work. Small volumes are within the power of one master.

Warming process

The sequence of operations for the installation of mineral heaters is as follows

A vapor barrier film is attached to the prepared wall.
A crate is mounted from wooden bars or metal profiles. The recommended guide pitch is 50 or 60 cm.
Rolls are cut according to the selected pitch. Cutting should be carried out so that the insulation enters between the guides tightly and, straightening out, provides a better fit to the guide.

Dowel dowel

Mineral wool is attached to the wall with plate-shaped plastic dowels, cut according to the thickness of the layer at the rate of 4-5 per square meter.
The windproof film is attached to the guides over the laid wool. The joints of the film are sealed with double-sided tape. Installation of insulation on the walls of the house.
Scheme of installation under the crate
Thermal insulation completed. You can proceed to the installation of the selected cladding - wooden or vinyl siding. To ensure the ventilation of the facade, a secondary lathing of thin laths is installed on top of the wind insulation.
Scheme of installation under plaster
Read on the topic -.
Installation of rolled foam insulation for outdoor and internal walls by itself is easier, but requires better surface preparation. It will have to be leveled more carefully - the foam will not be able to conceal irregularities as much as mineral wool.
It is not recommended to fasten foam rolls with a construction stapler - the staples create so-called thermal bridges through which cold can penetrate into the warm part of the room. The heat-insulating effect of the material is somewhat reduced.
How to fix the insulation on the wall:
- Clean and level the wall surface.
- Cut the material for butt jointing.
- In places of complex spatial shape - near openings, in corners, adjoining building structures (beams, balconies, etc.), it is better to try on cut pieces before applying glue or removing the protective layer.
- Apply glue to the heat insulator or remove the protective film from the adhesive layer.
- Glue the material, moving from the bottom to the top.
- Smooth the surface with your hands or a rule, achieving the best fit. If small air bubbles have formed, they should be carefully pierced in the center with a sharp needle and, moving from the edges of the bubble to the hole, squeeze out the air.
After half an hour, the glue will set and the heat-insulating layer will be ready for use. When installing the cork sheet, an adhesive specially designed for cork is used. It is applied both to the wall and to the cork. Before sticking the wallpaper, you should wait until the glue is completely dry to avoid warping.

2 Roll thermal insulation based on mineral wool

The quality of this category of insulation is regulated in accordance with the requirements of GOST RF "52953-2008". This quality standard allows the following heat-insulating material to be classified as mineral wool insulation:

Basalt wool is a material produced by remelting rocks and the subsequent formation of microscopic fibers from them, connecting into a solid carpet;
Slag wool is a material made from waste from the metallurgical industry. As a rule, it costs much less than basalt wool;
Glass wool is obsolete, but still quite often used due to its low price material. Produced by melting cullet.

Rolled basalt wool has a characteristic yellow tint

Roll insulation based on mineral wool, due to its elasticity and flexibility, is an extremely versatile material that can be successfully used both for thermal insulation of walls, floors, attics, and other flat surfaces, and for thermal insulation of pipes.

2.1 Mineral wool production

Consider the technology for the manufacture of mineral wool using the example of basalt insulation. Mountain basalt rocks, chemical composition which meets the requirements of GOST, can be remelted in two ways - hot and cold.

The hot method involves heating basalt rocks in blast furnaces, the cold method involves exposure to electromagnetic radiation (according to the principle of a conventional microwave).

The molten rock is fed into a centrifuge, which is equipped with permanently cooled carbide discs. Under pressure, molten basalt is fed into a centrifuge and falls onto rotating discs, where, in the process of carved cooling and pressure drop, individual basalt fibers are formed from the melt.

The resulting fibers are immediately removed from the drum by a special functional element and fed through the conveyor to the laying machine, which forms a carpet of basalt wool of the required thickness.

After laying the carpet, the fibers are impregnated with a variety of impurities that are necessary to give the final product the required characteristics - hydrophobicity, fire resistance, density and elasticity.

Slag, as a rule, has a darkish tint

2.2 Advantages and disadvantages

Among all the thermal insulation materials on the market in the middle price category, it is mineral wool that has the lowest thermal conductivity. Although the leaders in general are polystyrene and mineral wool.

An important factor is that the thermal insulation properties of mineral wool do not depend in any way on any external conditions - this material does not expand under the influence of moisture, does not undergo thermal expansion, microorganisms and rodents do not start in mineral wool.

Rolled mineral wool insulation is produced with a wide variety of performance characteristics - you can choose both low-density mineral wool for insulating pipes and other uneven products, and dense material for thermal insulation of surfaces experiencing external loads - floors or attic floors.

An important advantage of mineral wool is its fire resistance. This material can withstand temperatures up to 700 degrees, it does not light up even under the direct influence of fire. It is also worth noting good noise-reducing properties - by insulating walls and floors with rolled mineral wool, you will solve not only the issue of insulation, but also soundproofing the house.

The only drawback of mineral wool is the high vapor conductivity, due to which the installation of this insulation requires the installation of a special vapor barrier film.

Thermal insulation of the pipeline using rolled glass wool

Roll insulation based on mineral wool can be used for the following purposes:

Insulation of roofs, floors, walls, and any flat surfaces;
Thermal insulation of pipes and pipelines;
Thermal insulation of industrial equipment;
Warming element inside the sandwich panels (here best thermal insulation hitrock);
Internal insulation in false walls and when laying hollow walls;
External insulation of the walls of the house, followed by plastering.

Mineral wool insulation materials are widely used.

Their popularity is explained by high operational and technical indicators and relatively low cost.

Mineral wool-based roll insulation includes:

. The material is obtained as a result of the remelting of rocks of a certain type and the formation of fine fibers.
Glass wool. Insulation made from molten broken glass has an affordable cost. Due to this, the material is in high demand, although it is considered obsolete.
Slag. The material is based on waste from the metallurgical industry, so it has a rather low price.

Mineral wool-based heaters have their own distinctive properties:

temperature resistance;
low thermal conductivity;
high density;
absorption of vibrations and sound vibrations;
no shrinkage after prolonged use.

Foil roll insulation is made from expanded polystyrene foam by applying it to a layer of foil. The foil creates the effect of a thermos, pushing heat back into the room.

Expert advice: foil insulation can be used when installing an infrared floor, for thermal insulation of wooden saunas and baths.

The main properties of foil rolled insulation can be called:

high thermal insulation;
reliable vapor barrier;
good sound absorption;
fire safety;
durability.

Mezhventsovye roll heaters are a rather specific solution. The main purpose is to fill the empty space between the crowns. Even high-quality assembly of houses from profiled timber or logs cannot guarantee a snug fit of the elements. The interventional heat insulator will fill the free space.

The material is produced in narrow rolls, for its manufacture natural and harmless materials are used, such as linen, batting, jute. The use of this type of insulation is possible both during construction and during the operation of the house. Everyone knows that over time the tree dries out, forming gaps between the elements of the structure. Filling the resulting voids with insulation using a chisel and a mallet, you can keep the heat in the house as much as possible.

Heat insulators based on mineral wool

The materials of this group are the most common in the domestic market. This is due not only to their excellent operational and technical data, but also to an acceptable pricing policy - such a combination is still unattainable for competitive offers.

Flexibility makes work easier

Assortment and features of species

The term "mineral wool" is a unified designation for a number of heat insulators, namely:

basalt wool - for the manufacture of this material, the technology of remelting certain rocks is used, followed by the formation of the finest fibers on their basis, woven into a single carpet;
glass wool is a material, although it is obsolete, but still in high demand due to its affordable cost. For its production, remelted cullet glass is used;
slag wool - it is based on waste obtained in the metallurgical industry. Due to this, such a heater in rolls has a lower cost than that of basalt and glass wool.

Each of the varieties of mineral wool has its own distinctive features and features. So, glass wool perfectly resists high temperatures, up to 450 degrees - after exceeding this parameter, the material is destroyed irreversibly. The highest density is 130 kg / m3, thermal conductivity indicators vary in the range of 0.038–0.046 W / m * C.

Glass wool in rolls

Glass wool is not combustible, it does not even smolder, perfectly absorbs vibration manifestations, resists sound vibrations and does not shrink even during long-term operation. At the same time, the material is not moisture resistant, and its wetting completely eliminates the entire range of positive characteristics. It is worth noting the fragility of glass wool, as well as the fact that contact with human skin causes severe itching.

As for basalt wool, such rolled thermal insulation is able to withstand temperatures up to 700 degrees. Its thermal conductivity is 0.035–0.045 W / m * C, the density reaches 220 kg / m3. The material is resistant to moisture, slight wetting does not affect its parameters at all. Basalt wool is an environmentally friendly and non-irritating material.

Basalt wool

Slag wool has the largest mass, and its density reaches 400 kg / m3. The material is characterized by a minimum thermal conductivity - 0.046–0.048 W / m * C, and the highest temperature that it can withstand is 300 degrees - its increase causes the melting of slag and the destruction of its structure.

Slag wool in rolls

The dimensions of the materials largely depend on the manufacturer, but most often they have the following sizes:

length - varies between 3-6 m and more;
width - the standard figure is 0.6 and 1.2 m, although products of individual brands may have a width of 1.22 m and 0.61 m;
thickness - 50, 100 and 150 mm.

Wall mounting

Despite the fact that the roll insulation is created from different materials, it is mounted on the wall according to the standard principle. All differences will be in the composition of the adhesive that will be used, and, accordingly, in the drying time of the substrate on the wall.

Conditions for carrying out installation work with a substrate in the room

To glue the insulation on the walls of the apartment, you have to do the following:

First of all, it is worth preparing the surface, for which you need to remove the old wallpaper, plaster the wall, smoothing and patching up large cracks and bumps. Small defects in the wall surface can be left, they will close.
Next, the surface of the wall must be primed. This is done either with the help of glue, with which we will glue the substrate, diluted in a weaker consistency, or with the help of a special primer composition. After the primer, you must wait until it is absorbed into the wall and dries.
It is recommended to cut the rolled insulation into pieces of the required length in advance so that it can lie down and level out. This will make it much easier for us to glue it. When cutting the canvas, add a little material for insurance.
We prepare the adhesive composition according to the instructions on its pack. If we are dealing with a substrate with a top layer of paper, then we apply glue to the wall and to the cut pieces, while letting them soak in the composition for literally 5 minutes. If the substrate is equipped with non-woven edges, then it is enough to spread the wall, and the material will easily attach to it.

Next, we proceed directly to the installation of canvases on the walls. This process is reminiscent of wallpapering, the pieces are also glued together and carefully smoothed out. Air is expelled from under the canvas and it is firmly glued to the wall. It is convenient to use a rubber roller, it will create the necessary pressure and will not damage the insulation sheet.
After the insulation has dried, after about 1-3 days, we seal the joints of the canvases with ordinary masking tape. Krepp will give solidity to our design.
Now our walls are qualitatively insulated, and you can proceed directly to gluing the wallpaper itself.

Wall insulation will allow us to create the most comfortable living conditions. It will serve us for a long time, no matter how many wallpapers hang.
