Why do plastic windows sweat?

Why windows can sweat

For the average layman, it is a mystery why plastic windows sweat. What guesses you will not hear .. and the temperature drop, and the poor quality of the glass of the package and much more. Let's try to analyze in more detail what is the basis of fogging of window glasses.

Today, plastic windows can be seen in almost every residential apartment, as well as in a private house, in residential and non-residential premises. PVC windows have firmly taken their place in the market cell and are increasingly proving their advantages. They are based on the fact that such windows do not require insulation in winter and do not need to be painted every spring after snowfalls.

Reasons for fogging plastic windows

But sometimes even these excellent windows cause slight inconveniences - with a sharp drop in temperature outside around the window and, directly on it, condensation appears, as a result, the window sweats and flows, forming puddles on the windowsill. Let's remember the transition of the temperature regime in our old windows - the first window from the street, then some empty space and the second window.

Causes of sweating plastic windows

The difference between the outside temperature and the room temperature is protected by an air cushion between the windows. Double windows very rarely fogged up and were only partially covered with condensation. In what cases is the fogging of PVC windows noticed?

- windows sweat in the morning, as well as in the evening, remaining dry during the day;

- fogging more often occurs in winter or with a sharp cold snap;

- the window fogs up in one room, in all the others there is not even a hint of moisture condensation;

- the window always fogs up, regardless of the season or time of day, this happens extremely rarely.

What is condensate? This is the possibility of moisture condensation in the living space, which is explained by the high level of moisture in the air and its immediate settling on the surface, not only of glass windows, but also of other objects. This is the reason why plastic windows sweat a lot. In the fight against high levels of humidity, there are several ways, one of the simplest is airing.

The windows of the house fog up

It should be noted that an increased level of moisture has a bad effect on health and on the respiratory organs of a person, as it is a favorable environment for the growth of mold bacteria, viruses and fungi. When the room is ventilated, the air humidity is normalized and returned to normal.

Most often, they pay attention to the humidity after the plastic windows have been installed, because the previous windows had small large cracks, which helped to remove excess moisture from the room. The current plastic windows have a so-called ventilation mode, which helps to ventilate the premises, relieving it of excess moisture, while not losing heat.

What is room convection?

Convection in the room - is the mixing of air flows, where the air of warm temperature rises, only cold air descends. The room has some of its own laws of existence, which must be reckoned with. As a rule, windows and window openings are initially planned and installed above room heaters. The heating device heats the window glass and prevents condensation from settling.

Indoor convection

If, nevertheless, fogging appears, then the reason is that there is insufficient access of heat from the heating device to the glass. The reason may be not only poor ventilation, but also a wide window sill, insufficient heating of the glass, or an obstacle between the battery and the window. This leads to a disruption of the natural movement of air, as well as, to a malfunction, the convection of the room, which is the reason why plastic windows sweat a lot. The way to fight is to drill holes in the windowsill, thereby giving warm air access to the glass or getting rid of another individual reason.

Why do you need a wide double-glazed window - its advantages

Many people wonder why plastic windows sweat? The size of a glass unit "seventy millimeters" is just enough to keep warm in the house and not create unnecessary interference with the properties of the window. This is difficult enough to change if you already have windows fully installed.

Benefits of a wide glass unit

The only way in such cases is to constantly ventilate the room, which will help remove excess moisture that settles on the window panes and thereby dry the air in the living room.

Possible window defects during installation

Well, another reason is the defects in the window frame, which is a mistake made by the manufacturer or the expert installer. If there are a lot of windows in the room, but not all fog up, but only one, but you have already considered and excluded all of the above reasons, including thick double-glazed windows, then you need to contact the company that installed the windows. Defects of windows are very rare, so that the reason for the fogging of the window is most likely in the failure of the humidity in the room.

Window defect - fogging and fungus

When buying PVC windows, adhere to a few simple rules and then you will not have a question why plastic windows fog up, you will enjoy the warmth and comfort of your home:
It is not worth saving on a double-glazed window, because it is cheap single-chamber glass, packages that condense more often. Order a two-chamber or better three-chamber double-glazed unit with an energy-saving film. Better not to save. And don't forget - you don't have to pay twice. It may be worth purchasing an air dehumidifier if there is no way to permanently ventilate the room.

Installation of windows at home

And a few tips when installing new plastic windows:
Do not forget that the glass of the window must be constantly warming up - install the window near the heating devices. Ventilation of the apartment plays an important role - it is she who relieves the room of excess moisture. If necessary, clean the room ventilation system.

House windows installation

Vases and flower plants are very often found on window sills in living quarters, they not only emit oxygen, but also a large amount of moisture that settles on the glass. A simple solution to remove the flowerpots from the window during the cold season prevents condensation from forming.

Incorrect installation of the window and the passage of cold air is also one of the reasons for the fogging of the windows, in this case the call of the masters is inevitable, you cannot fix these problems on your own. We will be glad if we helped you to eliminate the problem of fogging of plastic windows and to eliminate minor inconveniences associated with this issue.
