What shape are the windows and why. Types of opening plastic windows and symbols on the diagram. Disadvantages of plastic windows

Today, windows are made from a variety of materials and can have a variety of shapes. Based on this, you can ask the question: what are the windows? The correct answer to the question is the classification of products.

For example, they can be divided into types according to the material used to make them:

• PVC structures;
• wooden;
• aluminum;
• combination windows.

In addition to the material, the frame can be divided into groups according to the design:

• paired;
• separate;
• single.

Today, products can be with single glazing or with double-glazed windows.

Classification of windows by material

Today, systems are manufactured using very sophisticated technologies, which achieves excellent results in heat and sound insulation. PVC products are very popular today. But for those who prefer the classic version, wooden frames are also made using new technologies. As a result, the finished product is radically different from the old wooden ones.

Metal-plastic.

Metal-plastic structures have been known to the world for over 50 years. On the territory of our country, they appeared much later. All products were imported from other countries, since domestic production was not established. Today, using the technology of leading brands, products are manufactured in the country. The metal-plastic device consists of:

• PVC profile;
• amplifier made of galvanized steel, which is located inside the profile chambers;
• high quality fittings;
• double-glazed window.

Using a PVC profile in a production environment, you can create a window of a completely different configuration.

Aluminum windows.

Many people associate aluminum with industrial buildings, offices, shops. It is in such establishments that aluminum window frames are most often used. Due to their strength, such frames are installed in houses where they will be exposed to intensive loads. Also, very often such metal frames are used for the construction of winter gardens, glazing balconies. It is this frame that will allow you to create a large window.

Wooden windows.

Previously, only wooden windows were installed in houses, which deformed over time, cracks formed through which heat was lost and cold entered. Today, in order to create a wooden window, new technologies are used. For the manufacture of such windows, solid wood or a three-layer beam is used. It is the use of glued laminated timber that completely eliminates the possibility of any deformation. The glazing is modern double-glazed windows with one or two chambers.

Combined type of windows

According to experts, such windows in the near future will take a leading position in the field of glazing. This is due to the fact that several materials are used in such windows, for example, wood and aluminum, wood and plastic, etc. By absorbing the most best qualities materials used, such windows will last a very long time without causing unnecessary trouble in their maintenance.

by the most bright option combination window is a structure made of a three-layer profile. The first layer is decorative, made of wood. The second layer is made of metal, it protects the structure from impact. environment and also gives the frame rigidity and stability. The third layer is made of polyvinyl chloride, the main purpose of using this material is to significantly increase the thermal insulation qualities.

Key Features

Windows are a source of natural light in the apartment and access to fresh air. This is especially important in apartments where ventilation systems don't work so well.

But at the same time, they create significantly greater heat losses in the cold season. It is through the glazing that the most a large number of heat. In order to significantly reduce such losses, it is necessary to choose the right profile, clarify the design of the double-glazed window, and check all the joints. Blinds and curtains can be additional measures to keep the heat in.

Double-glazed windows.

A very large role in the preservation of heat is played by the number of glasses in a double-glazed window. There are options for windows with one glass, but heat loss in this case will be maximum.

A double-glazed window, in which two glasses are installed, forms a kind of air gap, which will reduce heat loss. Modern double-glazed windows can have two or three sheets of glass. Additionally, the space between them is filled with dry air or gas.

All joints are closed with sealing profiles.

In addition to light through the windows, extraneous sounds and noise penetrate the room. Sound insulation will depend on the number and thickness of the glass. To minimize the passage of extraneous sounds, it is worth taking care of sealing all joints, not only the window structure, but also the junctions of the window with the opening.

When choosing a system, Special attention give the type of opening. Today, thanks to fittings, products can be:

• folding;
• rotary;
• swing-out;
• deaf;
• sliding.

Silent design.

This design does not involve opening the valves. The product is much cheaper than other options, and is as reliable as possible. It is rarely used in homes, since it is almost impossible to wash it from the street if it is not located on the first floor. The only option may be to completely remove the double-glazed window and then reinstall it. Blind windows can be installed on the side walls of the balcony or in the entrances. They can also be installed in private homes as a source of natural light in a corridor or terrace.

Folding design.

If the window is equipped with hinged fittings, it can be opened to the ventilation position (vertical opening). Normal opening is not available in this case. Like a blind window, this design does not have access to the outside, which prevents the window from being cleaned. Such a window can be installed in a place where full opening cannot be carried out. This is possible if the layout of the house does not have enough space to allow the sash to open fully. But, unlike a deaf one, such a window makes it possible to gain access to fresh air.

Swing window design.

The swivel design opens in the traditional way. This method allows access to the outside and adjacent doors. This design is very easy and convenient to care for. The disadvantages include the need for free space, which will allow you to freely open the sash. Such elements are installed in almost any room.

Swing-out design.

The most popular and common type of opening. Those. allows you to open both in the classic version and leave the element in the ventilation position. They are also installed almost everywhere.

Sliding system.

Such a metal opening system plastic windows appeared relatively recently. This method of opening allows you to open all the windows completely even in the narrowest room. Most often, such a system is used on loggias and balconies. The quality of windows with such an opening system is no different from the usual opening system. All joints are completely sealed and do not let cold air inside.

Plastic windows appeared on the construction market more than half a century ago. During this time, they have undergone many changes, and today they are distinguished by a variety of species. Many models different shapes and colors that manufacturers offer to the consumer, partly make it difficult for them to choose. What to focus on when choosing PVC windows?

Any type of PVC window has two mandatory elements:

• double-glazed window, consisting of several glasses, the inter-glass space of which is sealed along the perimeter of the contour;
• plastic profile (frame), which is a fixed part of the window structure. It is installed in the window opening.

Varieties of plastic windows by type of profile

The plastic profile has a complex design. In the context of this structural element compartments with small chambers that are filled with air are clearly visible, which allows you to keep warm.

The frame walls are formed by pressing molten polyvinyl chloride, to which modifiers and stabilizers are added. As a result, polyvinyl chloride acquires new qualities: strength to mechanical stress, chemical inertness, incombustibility, UV resistance.

The frame is chosen based on the characteristics of the climatic zone where the plastic structure will be used, as well as some other features, for example, the type of house, the level of thermal insulation and sound absorption.

The main indicators that are guided by when choosing a profile are its width and the number of air chambers.

Profile types

Frames are divided into three classes:

• "A" - a characteristic feature: a thickened outer wall, at least 3 mm.
• "B" - represents an object or lightweight profile. Minimum Thickness at the front wall is 2.5 mm. And finally
• "C" - has an irregular thickness.

The plastic profile can be normal or frost-resistant. For regions with an average monthly January temperature lower than -20 ° C, the profile marking must additionally contain the letter “M”.

Thermal insulation is affected by the number of air chambers inside.

From the outside, the PVC window profile looks monolithic. However, if you look at it in section, then you can easily find hollow chambers, from 2 to 8 pieces. They play the role of a kind of heat insulators. The greater the number of hollow chambers, the lower the thermal conductivity of the window unit. There are profiles:

• Two-chamber. This is perhaps the most unclaimed option, as it has low thermal insulation characteristics and does not meet rigidity standards;
• Three-chamber - a universal "budget" option that works both when glazing a balcony and when decorating window openings. This is an excellent solution for the southern regions;
• Four- and five-chamber - intended for use in regions with seasonal sub-zero temperatures, for example, for middle lane Russia. Usually they use double-glazed windows;
• Six- and seven-chamber - the most "warm" type. It is used, for example, for glazing French windows or extensive verandas. For the northern regions, the profile construct is chosen with an influx. It will protect the porch and seal from precipitation. The front wall should have a thickness starting from 3 mm.

PVC profile reinforcement

The strength of the frame depends on the type of reinforcement of the central chamber. There are several amplification techniques:

• L-shaped, installed on two walls of the frame,
• U-shaped - in three,
• closed - around the perimeter.

With a window height of less than 1.9 m, you can limit yourself to U-shaped reinforcement, and not overpay extra for additional reinforcement.

For reference!

Profile sealing is also important. The recommended number of seals is two. Then it is possible to exclude the deposition of condensate, due to which the insulation deteriorates and, as a result, a draft is formed. This is the most common problem faced by consumers.

Varieties of plastic windows depending on the type of double-glazed window

When glazing plastic windows, complex structures are used, consisting of 2-4 sheets of glass, which are fixed with a given step. On the outer part of the structure are sealed. The formed inter-glass cavities are called chambers.

Double-glazed windows in accordance with the number of sheets are divided into: one-, two- and three-chamber. Therefore, speaking of window cameras, it is necessary to clarify which cameras are in question - profile or in double-glazed windows.

• In a single-chamber double-glazed window, the distance between two sheets varies between 1.4–3.2 cm. The cavity between the sheets is closed along all sides of the chamber with a spacer. This is a strip of metal that separates the panes and keeps them at a calculated distance. If you look in the section, you can clearly see that in fact the spacer frame is a "P"-shaped profile. Its open side should be directed inside the frame.

There are small holes on the bottom of the frame. Through them, the chamber is connected to a sealed volume located inside the frame, where the absorbent is filled. The moisture absorber almost completely removes it from the chamber. As a result, whatever the temperature outside, window construction will not sweat.

However, single-chamber packages are not so in demand today. Basically, they are installed in stores, unheated or industrial premises, as well as other similar ones.

• Two-chamber. For residential buildings, double-glazed windows are more suitable complex design- two-chamber. They are slightly heavier than single-chamber ones, but the efficiency of noise and heat insulation is almost twice as high. And this despite the fact that the indicators of light transmission in both cases are approximately the same, and the cost of a double-glazed window is only slightly higher.
• Three-chamber. It is worth weighing well before buying such a double-glazed window: it is heavier than a two-chamber one, and reducing the width of the distance frame does not particularly contribute to an increase in the level of heat and sound insulation.

The characteristics of double-glazed windows are largely determined by the properties of glass.

• Heat-saving. At the factory, a metallized film invisible to the eye is sprayed onto the glass. Glass is absolutely transparent, because. it transmits rays of the visible spectrum. But heat rays reflect, therefore, heat does not penetrate through such a double-glazed window in summer, and on cold days it retains heat.

• Toned. Usually, staining glass is one of the steps production process: metal oxides or other chemical compounds are added to the mixture. This in no way affects the transparency of the block, but completely changes their appearance.

• Impact resistant. Ordinary float glass in them is replaced by tempered or triplex, which are just as transparent, but much stronger. It is the ideal solution for windows on lower floors, as it perfectly protects the window from acts of vandalism, whether accidental or intentional.

Glasses are absolutely safe: breaking, pieces of glass either remain on a durable film of polymers, or crumble without sharp edges.

• Noise-proof. To achieve the desired effect, several technologies are usually used, for example, the deposition of thin films or the filling of chambers with inert gases, which are reflected from the resulting intermediate surfaces, reflect sound vibrations and actively damp them. The level of their noise reduction is about 20% higher.

Plastic windows are designs that are distinguished by a large variety of species. They may differ in shape characteristics, number of wings, sizes, opening and closing methods, types of double-glazed windows and other parameters.

The correct name of modern plastic windows

The types of windows are very diverse, this is due to the growing interest in PVC structures from the population. To date, very often wooden structures are replaced with plastic ones, increasing the level of tightness, heat and sound insulation of the apartment.

Many are confused in terms, not understanding which systems should be attributed to PVC, which to plastic or metal-plastic. There is a difference between the concepts, because those structures that are now widespread should be called metal-plastic.

This is due to the fact that to create such systems, they use:

• polyvinyl chloride;
• metal for the frame;
• glass.

The use of a metal profile became a necessity, because the first PVC systems were not very durable and reliable. Modern models can be used even at high altitudes, they perfectly withstand wind loads, as well as heat and frost.

The main types of PVC products

Different types window frames differ in the material from which they are made, shape, color. For the frame, wood or aluminum is most often used.

By design features, window groups are divided according to the method of opening:

• swing;
• folding;
• sliding;
• deaf.

By the number of wings, there can be 1,2,3-leaf. Double-glazed windows come with one or more chambers that are filled with air or argon.

Having specified what types of such structures are, their main elements should be considered:

• frame, sash: made of PVC. The first is the basis, the second is the part that opens;
• double-glazed window: an element representing several glasses fastened to each other. This design is sealed, has dividers inside;
• fittings: mechanisms that work to open, close sashes, fix a certain position of the entire system.

PVC structures have a number of undeniable advantages:

• tightness;
• soundproofing;
• thermal insulation;
• affordable cost;
• durability;
• variety of types, sizes, designs.

The main difference between materials

When planning to order a window block, it is very important to first select the material from which the frame will be made. Each material has its own advantages and disadvantages.

The tree has the following advantages:

• the possibility of multiple staining;
• high environmental friendliness;
• good heat retention.

Disadvantages of wood:

• high cost (the design, which will isolate heat and noise at a high level, is prepared from a solid array, requires a double-glazed window);
• sensitivity to fire;
• the likelihood of drying out or damage by moisture, the occurrence of mold;
• requirement for constant care.

Aluminum has the following advantages:

• low price;
• light weight;
• the possibility of staining.

At the same time, metal frames differ low level keeping warm, they quickly let the cold into the room.

As for double-glazed windows, for a living space, double or triple glazing is optimal. It is so easy to achieve the desired level of sound and heat insulation.

Classification and varieties

What are the windows in houses? All systems are different from one another. For a high level of comfort, you need to consider the following factors:

• size;
• package thickness;
• the form;
• appearance;
• location.

When windows are installed in the room small size, there will be very little light inside, which will reduce the comfort of being. Large double-glazed windows, on the contrary, will expand the space and become an excellent decor. On the other hand, they will lead to significant heat loss, in addition, they will reduce the privacy of the room. This will require additional purchase of thick curtains.

Important! The norm is considered to be the transmission capacity of sunlight by 13%, while the optimal value is considered to be 50%.

Number of sashes at the window

What windows are by the number of shutters? Modern window blocks may have one to three wings. Separately, balcony systems are distinguished, where the wings are connected to the doors.

Single sash plastic windows

This option is considered the most economical, as a rule, the sash opens. Rarely, she remains completely deaf. In the Soviet years, almost all houses were equipped with just such structures.

Today there are fewer such systems, they are more often used in rooms. small area, garden houses. This is due to the fact that it is unlikely that it will be possible to provide comfortable living conditions in this way.

Double sided plastic windows

These products are equipped with two doors, they are universal, have a lot of positive properties, including an affordable pricing policy.

Sometimes, the first sash remains deaf, the second is equipped with fittings for opening. Sometimes both halves open. These structures are used almost everywhere in residential buildings, private suburban buildings, skyscrapers and low-rise buildings.

Three-leaf plastic windows

Such a system, as the name implies, is equipped with three wings at once. As a rule, they are placed in rooms with a large space: halls, living rooms, dining rooms. This design is ideal for tall windows.

Opening doors are usually placed along the edges, leaving the middle muffled. Sometimes all doors open, this equipment option has the highest cost.

Type of window opening

The next classification is the division according to the type of opening. The fittings that are used in such devices are necessary to ensure the opening of the valves. It is she (or rather, her quantity) that has a significant impact on the final price of the block.

Most often, customers prefer to save money by installing fewer opening doors than they would like, and it was convenient. Following this path, do not forget that a lot depends on the quality of the fittings. Therefore, you need to save on the number of such elements, but not on their quality indicators.

Blind plastic windows

Deaf structures are cheap, but they also deliver maximum inconvenience during operation. For example, they create difficulties with washing, because it is sometimes simply impossible to get to their outer side. However, it is this system that is the most reliable, easy to manufacture, and also has no mechanisms that can fail and require replacement.

Such blocks are chosen for the first floors to prevent burglary, on balconies and other places where caring for them is not difficult.

Swivel plastic windows

What are the types of structures equipped with an opening mechanism? First of all, you should consider rotary systems. They are used most often, the sash opens, which makes it easy to clean it from both sides, ventilate the room.

Here, one should take into account the fact that a fully open sash will let a lot of cold air into the house (in winter), which will cause instant cooling of the room.

Another significant disadvantage of the swivel mechanism is the inability to fully use the useful space of the window sill. Because to open the window, you will need to constantly move all the objects on it.

Tilt and turn plastic windows

Windows, the types of which are equipped with a tilt-and-turn device, are installed most often. Such a system is very convenient, it allows you to:

• tilt the sash without affecting the area of ​​\u200b\u200bthe window sill. At the same time, the flow of fresh air will not be too intense, which will allow you to keep the window ajar even at night. For this purpose, there is a micro-ventilation function;
• open the door completely to quickly ventilate the room or freshen the air in summer, wash the glass surface on both sides.

transoms

This type of opening is less common, it is mounted where the opening of a full sash is not required, only periodic ventilation is sufficient. The window, at the same time, only leans back, up or down.

The design has an analogue among pre-existing wood structures, where there were windows of impressive size. Today, transoms are not too expensive, but are rarely used, most often in office space.

Sliding plastic windows

Sliding structures are most often mounted on balconies, loggias, verandas, terraces, in a word, where there is a direct exit to the outside. This mechanism becomes an excellent way out for rooms of a small area, because an open window does not take up any space at all.

The sliding structure works like this:

• the sash opens by moving to the right or left (or both directions);
• the part slides along the guides installed on the bottom of the frame;
• glass slides strictly in the window plane, without going beyond it.

According to the shape of the window opening

Varieties of such systems in the shape of the opening can be completely different. PVC is a material that easily accepts various forms which are actively used by designers and architects.

Exquisite designs allow you to perfectly emphasize the overall style of the building, to give the missing touch of decor.

It can take the following forms:

• rectangular;
• square;
• round;
• triangular;
• trapezoid;
• oval and others.

Standard multi-storey buildings are equipped only with square and rectangular blocks, the rest are often used in suburban private buildings.

Triangular plastic windows

There are different types of windows. Triangular ones are often mounted on the upper floors of low houses, decorate attic, attic rooms. The triangular block fits perfectly into buildings with a pointed roof, giving them a complete look.

Sometimes such forms are required for the full implementation of the design of houses according to the high-tech style, or modern classics.

When choosing such a form, it should be remembered that a lot of materials will be required for its manufacture, sometimes even more than for a standard design. Therefore, the cost of the block will be higher.

Rectangular plastic windows

The rectangular shape is the most common, it has a lot of advantages:

• universality;
• minimum consumption of materials;
• acceptable price;
• ubiquitous application;
• ease of maintenance, installation and implementation repair work, which is associated with the use of standard fittings.

Round plastic windows

Round windows are not as common as, for example, rectangular ones. However, their use almost always guarantees an excellent result, original in its architectural, design idea.

Install such windows that look like portholes in bathrooms, skylights both in apartments and hotels.

Such models practically do not differ in cost from standard ones; a large amount of material is not required for manufacturing. This indicates that such structures, over time, will increasingly frame window openings. This is especially true for private houses, where architectural thought has complete freedom.

Arched plastic windows

PVC arches are semicircular structures that describe an arc of a certain radius. To simplify, arched systems can be called halves of a whole round window.

Such configurations are often used for glazing buildings of religious significance. For instance, Orthodox churches equipped with semicircular, Gothic - lancet varieties.

The cost of such blocks does not differ in height, so they are often used to equip cottages, low houses located in the private sector.

Trapezoidal plastic windows

Trapezoidal PVC systems are used almost everywhere. They fit perfectly into rooms of different styles, combined with all sorts of design solutions. Such designs are able to fit well into any interior and exterior of buildings.

Trapeze on the facade can give a touch of sophistication, originality and chic to any home. Especially often they are used for installation on gable buildings. Here, such solutions allow you to visually enlarge the space, contribute to the penetration of a large amount of natural light inside.

The window is one of the main elements of any room, affecting the creation of coziness and comfort. Most people understand by these concepts light, warm room where peace and quiet reign. However, this effect can be achieved only with the help of a high-quality window that does not let street noise into the room and does not release heat into the street.

The most popular designs are plastic windows. In connection with the development of popularity, many varieties of plastic windows have been developed.

Plastic windows have a number of advantages - low cost, resistance to moisture and other natural phenomena, no need for additional care. To choose a truly reliable and convenient window, you need to familiarize yourself with the types of available designs.

What is a plastic window made of?

1. A frame is an element that is attached to a window opening in a building wall. It completely repeats the shape of the opening, so the frame is made individually in accordance with the shape and size of the window opening. The frame is made of metal-plastic profile.
2. The sash is the movable part of the window, attached to the frame by means of hinged canopies. One window can have several sashes. It depends on the individual preferences of the customer.
3. A double-glazed window is several glasses arranged parallel to each other and hermetically fastened together. Double-glazed windows are inserted into the frame and sashes of the window. The number of glasses and their thickness is selected individually, depending on the preferences of the customer. There are single, double and triple glazing.
4. Glazing beads are plastic strips that hold double-glazed windows in the seats of the frame and sashes.
5. - these are mechanisms for opening and closing window sashes (hinges, locks, handles, etc.).
6. Window seals seal the joints between window structural elements.

All plastic windows consist of the listed elements, however, their individual design, quality and physical characteristics allow you to create windows that are radically different from each other.

Main technical characteristics of plastic windows

The reliability and functionality of the window consists of technical features each individual element. There are standard ready-made window sets for those who do not understand the features of their design.

But you can arrange all the elements at your discretion, and for this you need to understand the features and varieties of components.

The metal-plastic profile is a reinforced PVC, from which the supporting frame of the window (frame and sashes) is created. Main specifications profile: heat transfer, profile width and number of chambers in it.

Metal-plastic profile parameters:

1. Chambers are partitions inside a metal-plastic profile, each chamber has its own purpose. The most common is the three-section profile. One section gives rigidity to the structure, the second carries out the outflow of condensate, the third is needed for fastening the fittings. However, there are four, five and six-chamber profiles. The number of chambers directly affects the thermal conductivity of the window frame, because each section is filled with air, and it is a poor conductor of heat.
2. Increasing the profile width makes it possible to increase the air gap in the chambers, and also provides the possibility of installing thicker glasses and double-glazed windows, and this, in turn, provides more reliable protection against external noise and heat leakage.
3. Heat transfer is a value that characterizes the profile, taking into account all the advantages and disadvantages of the design.

double glazing

A double-glazed window is several connected glasses that create air chambers between themselves. It can be single, double or triple. The glasses themselves can also have different thicknesses.

Double-glazed windows are various kinds:

1. – the inner glass is covered with silver atoms, which ensures the reflection of heat from the radiators and reduces heat loss.
2. covered with light-absorbing material.
3. Impact-resistant double-glazed windows are treated with a special resin, which increases their strength.

How does changing the parameters of glass affect the reliability of the window:

1. The number of glasses in a double-glazed window provides better thermal and sound insulation. However, a large number of glasses with strong noise can get into resonance from vibration, which is a source of noise and destruction of the window structure.
2. The thickness of the glass in a double-glazed window directly affects the thermal conductivity and sound insulation of the window. The thicker the glass, the better the insulating properties.

Triplex has the best insulating properties - this is ordinary glass coated with a special transparent film that increases the strength of the glass and other physical characteristics.

Types of plastic windows

There are several types of plastic windows that differ in certain characteristics:

1. Window shape. This parameter is determined by the shape and size of the window opening. There are round, square, triangular and other windows.
2. The color of the window is also determined by the individual preferences of the customer. The most common colors are white, brown and other colors that mimic expensive woods.
3. The type of sash opening is selected individually. There are the following types of opening: folding (fanlight), rotary (traditional), tilt-and-turn (complex) and spool (type of closing "sash in the sash"), sliding, rotary-sliding. A window can also be without shutters at all - a blind window.

Swivel opening of the window is carried out by vertical canopies. The disadvantage of this method is that the sash has a large span (takes up a lot of space) and there is no possibility of adjusting the air flow - the window can swing open under the pressure of the wind.

The hinged mechanism allows you to slightly open the sash, slightly tilting it - this ensures smooth ventilation of the room, while the window is almost closed.

Tilt and turn plastic windows are equipped with a mechanism that allows you to open the window with two different ways– traditional and folding.

The sash-to-sash slat opening provides a large open space when both sashes are open.

Sliding windows move on rollers along the plane of the window (as in a closet). This mechanism has an excellent advantage - saving space.

Tilt-sliding windows open a little on themselves, and then move to the side. This option is much more convenient than the traditional opening.

What design of a plastic window is the most reliable

The most reliable plastic window is considered to be a design that provides the best thermal and noise insulation. If you have an unlimited budget and use every opportunity to improve the characteristics of the window, then you can assemble the following design:

1. Use a six-chamber metal-plastic window profile with a width of 90 mm for the supporting structure of the window.
2. Insert a triple-glazed window into the profile, the chambers of which are filled with an inert gas to improve the insulating properties of the window. For even greater insulation, you can use triplex, energy-saving and tinted glass.
3. Install sashes with a complex mechanism that allows you to open the window in a hinged and rotary way. If you need to save space, you can install a sliding sash.
4. It is better to choose a plastic window among the most famous brands: Veka, KBE, Rehau, etc.

Even the best plastic window will not be reliable and durable if installed incorrectly. Therefore, it is better to contact a well-known company that employs qualified specialists.

Some features that should be considered when arranging the design of a plastic window:

1. If you increase the number of chambers in the profile, then you must definitely increase its width, if this is not done, then the desired insulating effect will not be achieved. For example, for a three-chamber profile, the optimal width is 60 mm, for a six-chamber profile, 90 mm.
2. To increase the sound insulation of double-glazed windows, but avoid vibrational resonance, you need to alternate the thickness of the glasses. For example, the thickness of the outer glass is taken equal to 8 mm, and the next glass - 4 mm, and so on.
3. The fittings of the window should ensure a snug fit of the sashes to the frame and provide the possibility of adjustment.

During window operation, most of the heat escapes through the glass surface and not through the frame, so there is not much point in installing an expensive six-chamber profile. And in the case of a double-glazed window, it is better to install a two-chamber version with alternating glass thickness, but increase the distance between the glasses.

If you stock up on information, then it will not be difficult to make a reliable choice of a plastic window. The main advisers for choosing high-quality and durable products are certificates and technical specifications. After all, sellers can embellish the benefits of the product.

Window opening pattern is enough important element, helping to navigate how to put furniture and generally make housing more comfortable. It can be displayed on the plans; sashes can be hinged or sliding, open in different directions. We will tell you in more detail what types of windows are and how they are reflected on paper.

How can the doors open?

Types of opening plastic windows are quite diverse, which allows you to use the window in any interior, making it the most practical and functional. Most plastic structures open into the room. In addition, their upper part can be pulled towards you and put into winter ventilation mode. However, this is the most familiar and standard way, opening plastic windows can be carried out according to other schemes:

• . Most often installed in shops or residential premises as additional window. Such a sash does not open, it does not allow airing the room. In the diagram, such a window will be indicated by a rectangle with a cross in the center.
• window openings are more popular. The sash can turn, often inward, but on some designs it opens outward. Usually these are made to order, as they are quite rare. One side of such a window is hinged, the second is closed with a handle, when turned along its axis, the fittings change position, allowing you to open the sash or put it in the desired position. The designation of opening windows on the plan is quite simple: it is a rectangle, inside of which there is a triangle. Its base points to the side where the hinges are, and the top is directed to the side where the handle is located. He can look left or right, depending on which way the sash opens.
• . The window opens by turning the handle, but is separated top part sashes, completely folding options are quite rare. Usually this is a winter ventilation mode, and this method of opening is combined with a hinged one. If the window opens only on itself, then on the diagram it will be reflected in the form of an isosceles triangle located in a rectangle.
