The windows have long become, not only a means of ventilation of the apartment, and as a source of natural light, but also as an object of decor, so it is worth a choice, it is especially careful in our time. No one already uses the services of old windows, which most often consisted of wood, were covered with ordinary paint.
Such old -fashioned window frames, poorly kept warm, quickly got dirty and deformed under the conditions of rain and snow, which for our ramps is quite banal phenomena. Wooden windows were replaced, metal -plastic windows, with a large number of cameras. They hold the heat into the apartment in the winter, and in the summer they do not allow moisture and hot air to seep into the room. On such windows, condensate does not accumulate due to their tightness.
Tightness also allows you to hold all sounds coming from there on the street. If you look purely from an aesthetic point of view, then metalloplasty, this is material that practically does not need care, that is, the windows are constantly white, and only occasionally they have to wash them.
The disadvantages have this category, namely their quality. Although the windows do not pass heat, moisture, that is, they hold the temperature in the apartment at the same level, but still they quickly fail, and certainly it cannot be said that they can hold out for 50 years, as often indicated in advertisements.
In this case, you can resort to a double version, past and new time. More recently, window frames made of wood according to the metal -plastic system appeared. More precisely, the frame is also multi -chamber, holds noise and controls the temperature in the apartment, but the tree is processed in production, which significantly prolongs his life, even with the most severe climate.
