A window is an opening in the wall that is used to enter the room into the room and provides ventilation. Their size, location and quantity are important indicators in the design. Windows in wooden frames with one or two glasses are usually made, depending on the type of room. Air chamber forms in the windows with two glasses, which increases the thermal insulation of the room. To enhance thermal insulation, sometimes three and four glasses are used. Wooden frames are subject to corrosion, so they require constant care. In the modern world, double -glazed windows are more popular, which are hermetically attached into metal -plastic, wooden or aluminum frames, the sash of which are equipped with rubber seals, to protect against drafts. Metal -plastic windows are made of PVC profile, inside of which there is an aluminum profile.
The airspace that forms between the profiles, which significantly increases thermal insulation. Metal -plastic windows can be single -chamber and two -chamber. Two -chamber naturally give a much higher level of heat — and sound insulation than single -chamber. The plus of metal -plastic windows is that they do not need to be painted and compacted from moisture penetration. Such a window can be opened in two ways thanks to accessories and special mechanisms. Aluminum windows are made from aluminum profile. In appearance and their qualities, they practically do not differ from previous double -glazed windows. Their plus is that they are stronger and can carry a large load. This allows you to use them for large windows production.
