Price The total cost of a window unit depends on the dimensions, configuration, requirements for the design of the structure, the complexity of installation and some other nuances.
The role of air chambers in PVC windows Closed longitudinal air chambers in window frames play a dual role. This is an effective thermal insulation and reinforcement of the structure. External chambers, in addition, serve to remove condensate that forms inside the cavity due to the temperature difference in the room and outside. They are connected to the atmosphere at the bottom and drops of water simply flow down to the street. The presence of such holes has practically no effect on the overall level of thermal insulation.
Frame profiles are slightly different. There are separate designs for bearing racks, sashes, crossbars). In any case, profiles from one manufacturer are used for one window, which are cut at the factory to the required length and assembled into one structure. The elements are connected by special welding or mechanical hardware.
Plastic can hardly be called an environmentally friendly material, but modern manufacturers have tried to make it as safe as possible for humans. In its manufacture today, components that are harmful to health are not used.
The reinforcing element of the window is a U-shaped or square profile, which is inserted into the largest chamber located in the center. The thickness of the sheet metal from which the profile is formed is in the range of 1.5 - 2 mm. It is made of galvanized steel and is highly resistant to corrosion. An amplifier is installed in almost all structures, although according to the standards, with a frame length of less than 0.8 m, it can not be used.
Metal-plastic windows have practically replaced wooden structures, since they are absolutely maintenance-free and durable. The choice of metal-plastic windows is a responsible task. Do not give preference to cheap designs. Saving on materials and accessories will negatively manifest itself already with the advent of the first cold weather.

It is only important to notice the damage in time so that the repair does not fall on the cold season, when it is not very convenient to open the window.
Double glazing. When choosing a metal-plastic window, it is important to focus on the quality of a double-glazed window, which differs in: the number of glasses (respectively, the more of them, the more reliable the noise insulation and the higher the energy saving; the best option is a two-chamber option); type of glass (manufacturers offer various options, including incandescent and energy-saving ones, be guided by your own individual needs when choosing).
Certificate of conformity to GOST 30673-2013 for the profile, test reports for intra-profile ventilation, conclusions of laboratory tests for durability and resistance to climatic influences, as well as other documentation confirming the quality of the exprof profile, you will find in the appropriate section on the website.
