It can also be matte, tinted, reflex, reinforced.

From the point of view of constructiveness, plastic windows do not differ from wooden ones — a window box and wings. If the window has a large size, the glazing field is separated by impost. But, it should be noted that thanks to modern technologies and the development of new accessories, the operational characteristics of plastic structures are an order of magnitude higher. For example, a double -glazed window is a design of two or three glasses with hermetic gaps between them. The heat -insulating window level directly depends on the distance between the glasses in the double -glazed window: the greater the distance, the better thermal insulation. External and inner glass differ in thickness. This ensures the elimination of possible sound resonance, as a result, a decrease in the noise level in the room. In the manufacture of modern plastic windows, ordinary glass is used. It can also be matte, tinted, reflex, reinforced. There are also plastic windows with energy -saving glass. Such glass prevents infrared radiation outward, while without problems passes sunlight inside the room. Thanks to the invention of such a double -glazed window, there is no need to produce windows with two separate wings. Sales can be opened in two directions: for intense or cloth ventilation. Windows are also produced in which the sash does not open at all. This option of plastic windows is cheaper. PVC materials are characterized by a fairly high strength of strength, they are not influenced by external factors as an increased level of humidity, the effects of sunlight and temperature differences. Plus, using plastic, there is an opportunity for non -standard decoration, creative design. PVC is characterized by a very long life. And if you take into account that the plastic windows almost do not need care, their advantages are not questioned.
