Why is there no good air exchange in a house with plastic windows?

In the old days, only wooden windows were installed in every apartment, in every house, in social buildings, socially important institutions. Today everything has changed. Owners of residential and non-residential premises invest a lot of money by buying plastic double-glazed windows, believing that this is the best option for maintaining heat in the house. After several months of operation, it becomes clear that:

• Glasses “sweat”
• A fungus appears on the walls,
• The room is not that hot, very stuffy.

And all this is due to disturbed air exchange. The blame is on plastic, which supposedly "does not breathe."

How was it with wooden windows?

No need to be mistaken. Wooden windows “breathed” only because there were microcracks in the frames. Over time, wood will dry out and fresh air will enter the room through small openings. This is the breath of wooden frames. Nothing more. Therefore, even when the windows were sealed for the winter, the air exchange was still as good as possible. From the microcracks in the frames went through, and it was simply impossible to seal them.

Plastic windows violate the air exchange in the room, as:

• Frames do not crack;
• Between the glasses and the frames are installed high-strength sealing gum that prevents drafts from entering the room.

It is warm, cozy and comfortable in apartments and social institutions, but due to disturbed air exchange, there is some dissonance, discomfort, side effects.

We install ventilation and buy the right windows

Today, technology has gone far ahead. Manufacturers understood what the problem of plastic windows was, therefore they began to produce special models supplemented by micro-ventilation. However, sometimes integrated microventilation is not enough. In the room it is necessary to install special forced ventilation in the wall, in a special ventilation shaft.

The first option is more suitable for urban apartments and residential buildings of country houses. Forced ventilation installed specifically in the shaft is suitable for:

• City toilet rooms;
• Bathrooms
• Rooms with high humidity;
• For kitchen spaces.

Forced ventilation, powered by electricity, is good because it can be turned on at any convenient time, when necessary. The system built into the wall works around the clock, almost without human intervention. In both cases, the problem of poor air exchange in the apartment due to installed double-glazed windows is solved once and for all.
