Why plastic windows are sweating: reasons, solutions

Winter brings with it not only a festive mood, along with the cold in the house comes a problem associated with the emergence of condensation on plastic double-glazed windows. Why do plastic windows sweat? Let's try to figure it out together.

Remember the school physics program - the higher the temperature of the environment, the more moisture is contained in the air. It is only necessary to cool the air, as condensation of steam occurs, and it settles on the surfaces in the form of drops. And, of course, settles in the first place where the temperature is lower. Usually the coldest surface in the room are double-glazed windows, which means that the reason why the windows are sweating is a fairly low temperature on their surface.

We have dealt with natural phenomena, now we need to find the cause of the troubles in the apartment, because, anyway, the condensate on the double-glazed windows is an abnormal phenomenon, an indicator that not everything is in order here.

So, why do plastic windows sweat:

1. No normal ventilation in the room. This happens when the ventilation ducts are clogged, they are usually located in bathrooms, bathrooms and in the kitchen. In this case, nothing will help, except how to deal with ventilation ducts and do it as quickly as possible.

2. Due to the purpose of the room, there is constantly increased humidity in the room. With this constantly face the mistress in the kitchen. Cooking, washing dishes. And in some families, where there is a small child, the kitchen constantly includes a washing machine and clothes. These factors increase the humidity of the air. If the windows sweat only for this reason, the only way out is the frequent airing of the kitchen.

3. The owner is very economical, and decided to put a single-chamber double-glazed unit in the room . This saving, including on oneself, is the reason why plastic windows are sweating: the glass will be very cold, because for good thermal insulation of two glasses is not enough.

4. The next cause of condensation in the windows is the recently completed repair in the room or the recent settlement of the house. Building structures, finishing materials for a long time retain high humidity. It is only time that can eliminate this cause.

5. Incorrect installation of the window, that is, it is deeply deepened in the window opening. Usually this is done at the request of the owner himself in order to increase the surface of the sill. Numerous flowers placed on it will also inevitably lead to condensation. Even such a beautiful decoration can be the reason why plastic windows are sweating. The choice is the owner: either the absence of flowers on the windowsill, or condensation on the double-glazed windows.

6. When installing windows, the rules were violated. If there are crevices when installing the windows, they are a source of penetration into the cold air, which, mixing with warm air masses, cools them to the "dew point", and condensation forms on the double-glazed windows. Such an oversight is better to fix right away, not postponing for later. Call the representatives of the company that was engaged in the installation. It should, however, be remembered that the standards that are provided for window units do not affect the rate of condensate formation, because there are many reasons why this condensate can occur.

7. Incorrect installation of heaters in the room. The windows sweat if they are installed far from the battery, another heat source. The situation can only be corrected by moving the instruments.

Summarize all that was said in the following recommendations:

· Check and repair ventilation defects.

· Pay more attention to thermal insulation, including walls outside. A reference point for maintaining a normal indoor climate should be a temperature of + 20 ° C.

· Eliminate all sources affecting the humidity in the room. This can be the flow of the roof, the accumulation of moisture in the basement, etc.

· Air often the room in which you live.
