Metal -plastic windows are the most high -tech method of blocking the window opening today. They are simply mounted, and operational qualities are at the maximum possible level.
However, in addition to obvious advantages, this technology also has serious disadvantages, among which it should be noted of low cold resistance. Ideally, metal -plastic windows are practically not exposed to low temperatures, however, poor -quality installation, incomplete equipment or lack of proper care can adversely affect the operational qualities of the product.
In the winter period of time, the window opening can be drawn with cold or even openly blow out with a draft from the outside, which indicates the need to take measures to warm.
