Why do plastic windows sweat?

windows In modern repair of an apartment, they are increasingly equipped with PVC windows. They do not need to be permanently strengthened or painted, dust and noise from the street do not penetrate through them. However, even with such a qualitative design, there are sometimes problems. Condensation may appear on the windows, which causes a lot of inconvenience, besides, they look quite unattractive. Let's find out why plastic windows are sweating and how to deal with condensate.

How is the metal-plastic window made?

Its frame consists of a plastic profile, light penetrates through the glass. To produce the profile, polyvinyl chloride is used with various additives.

Important! Plastic, despite a lot of advantages, the material is not the most durable. Glass weighs a lot, so in order to strengthen the frame, use metal inserts.

Components of PVC windows:

• Frame - load-bearing frame, the installation of which is carried out in the opening. The frame is the basis for fixing the double-glazed windows and all necessary fittings. As a seal, rubber is used that does not allow moisture or air to pass through.
• Valves - can be deaf or mobile. They are a kind of skeleton for double-glazed windows. The sashes, like the frame, are manufactured with metal reinforcement.
• Fittings - handles, hinges, opening mechanisms. Additional devices are represented by blockers, microlifts and the like.
• Double glazing - the glass itself. They can be two, three or more. The thickness can be different. All of them are tightly connected to each other.

Important! In the space between the glasses, an aluminum frame is mounted, the cavities of which are filled with absorbent. Thanks to this glass it is possible not to get fogged up, but only on condition that the package is hermetically sealed.

Reasons for sweating windows from within

It seems that such a reliable construction should remain completely sealed and there is absolutely no condensation in it. Flour windows for completely unexpected reasons.

High humidity

This cause of fogging is the main reason. The reasons for high humidity may be several. Why do plastic windows sweat in the first place? Because of the quality of heating the apartment, when it's cold outside.

At this time, a strong cooling of the plastic window occurs, and if the room - with high humidity, there is an increased condensation. In this case, you should refuse to heat the room with a gas stove.

Important! Heating the apartment with a gas stove harms health, besides, condensation occurs on the windows.

Cooking

In the kitchen, steam forms during cooking. All this eventually becomes the cause of moisture formation. If ventilation of the kitchen is insufficient, this should be taken care of:

• Regularly check the ventilation shaft;
• Get rid of collected dust and sand;
• If necessary, use an electric hood.

If you do not take such measures, you will continue to observe how the plastic windows sweat regularly.

Important! While the cubic meter of gas burns, oxygen burns in a huge amount: 13-15 cubic meters. It is necessary to take care not only of the ventilation of the room, but also of the supply of oxygen.

Washing

This is an important process, and it is not the last place in the question of why plastic windows are sweating from the inside in a private house. If things dry in a room - this leads to an increase in humidity. And in the end, because of the condensation formed mold and fungus.

Poor installation

Of course, a lot of attention should be paid to the very installation of the window. Savings lead to the order of work for non-professionals. As a result, the requirements and installation rules are violated:

• Often, the sealing of the window and the window opening is impaired. If there are cracks - nothing prevents the cold and damp air from penetrating from outside, and as a result - the windows begin to "cry."
• The leaflets are often tilted relative to the frame, which results in loose fit. If there are gaps, cold air penetrates. And if in the street a strong wind - an unpleasant strong "whistle" is shown.
• In the event that the sill is not properly mounted, moisture is also formed.

Important! It is necessary to check how well the slopes are made. When using plastic or gypsum board, it is necessary to check the tightness of the mounting foam. If there is a draft, the slope is dismantled.

Heating source

If there is no normal heating, the room rises in temperature, eventually the window fogs up:

• If the battery is under the window, the bottom of the plastic window may freeze. The reason for this is the overhanging sill. Because of it, the circulation of heat from the radiator to the window is impossible.
• A decorative finish can become a hindrance to normal warm air circulation. If the windows in the apartment are sweating for this reason - what should I do? Just get rid of the grilles, which are too "throttled" heaters.
• In the event that there is no central or individual heating, and for the heating of the room using electric heaters, there is overdrying of the air. All this leads to a disruption in the circulation, as a result - water on the windows.

Constructional features of the building:

• Newly built house made of bricks, and the windows, despite their quality, are still covered with condensate? The reason is in poor ventilation. In this case, it is quite difficult to determine why the windows are sweating. Preparing food, drying clothes, humidity from the bathroom - all this remains in the room. Including, and on the windows.

Important! The only way out is airing, even in the winter.

• Also problems can be caused by a too large window sill, which prevents warm air from coming from the battery. If the reduction in the sill is not possible, you can make holes in it to give way to warm air.
• Why do windows sweat in winter and how to eliminate this trouble? In the new house, shrinkage can occur, which leads to the appearance of cracks near the frame. In order to eliminate them, you can use liquid plastic.
• If the house is under repair, do not be surprised at the appearance of drops on the glass. Moisture gives both a drying screed and plaster. The only way out is by airing.

Cope with the fogging of

glass Factory marriage is unlikely to be corrected, but here you can avoid the main unpleasant moments:

• Single-chamber package is not the best choice. It is better to choose a triple glass.
• Ventilation grilles and channels must be cleaned.
• Before winter, it is necessary to move the PVC window into winter mode. Otherwise - the insulation will remain low, the internal window will be too low temperature.
• Do not make the windowsill plants. They need to be constantly watered, and this leads to additional humidity.
• Any windows require constant airing, every day for at least ten minutes.
• After the summer heat, you should always inspect the sash for sagging, check the seals. If necessary - the window needs to be adjusted.

With our advice, you can deal with the problem. Often, getting rid of fogging is very easy and you do not need to change new beautiful windows.
