number of chambers in double-glazed windows A single-chamber double-glazed window is more suitable for regions located in a subtropical and temperate climate, houses located in quiet neighborhoods. A double-glazed window is the best choice with the best heat and sound insulation characteristics (provided that the profile is chosen correctly), a universal option for both city apartments and private houses, it can be used not only in temperate, but also in subarctic climates

Most of them are made on the basis of high-quality float g

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.

Given the characteristics of glass as a material with a certain rigidity, spatial structures like double-glazed windows are distinguished by certain size restrictions. They can be within a minimum of 300mm on one side and in an aspect ratio of 5:1. But the maximum glazing area should not exceed 3 m2 in a single-chamber package with 4 mm thick glass and 4.2 m2 with 5 mm glass thickness.

The ends of the double-glazed window are sealed, the air inside is dry and the glass does not fog up at any temperature inside and outside. In modern double-glazed windows, instead of air, an inert gas is sometimes pumped, most often argon. Its thermal conductivity is somewhat lower than air, but the cost is higher. Whether such a step is justified in terms of energy saving is still a matter of debate. But in relation to the price - manufacturers win unambiguously.

PVC windows have recently appeared on the market, the cavities of which are not filled with air, but are filled with foamed heat insulators - expanded polystyrene, for example, or filled with fiberglass materials. Even with a relatively small number of chambers, their thermal insulation characteristics are much higher than air ones. But for now, their price is also higher.

To be convinced of the quality and high consumer properties of plastic windows, you just need to read about their characteristics in the article brought to your attention and compare them with wooden structures. The text is far from advertising in nature - only objective information. The choice of priorities is up to the reader. Here you will learn how to choose plastic windows, and why some designs are better than others.

Disadvantages and the issue of environmental friendliness The frames of plastic windows have one significant drawback - non-repairability. Scratches, scuffs and other surface damage cannot be repaired on plastic. However, plastic is much harder than wood, and it is more difficult to scratch it during operation.

How to determine the quality of the profile The first thing you need to pay attention to when buying windows is the appearance of the plastic. If the window is not laminated with decorative wood-like film, then the type of material will tell you a lot. High-quality polyvinyl chloride is a monolithic material, completely smooth, uniform in color. If spots are visible on it, or, worse, small or large grains, this is a fake, which is not worth buying in any case.

The design of the double-glazed window and the purpose of the constituent elements The double-glazed window, as a window structure, appeared quite a long time ago, almost 90 years ago. It has become a worthy replacement for double windows, simplifying their arrangement and retaining the main properties. Their technical essence is simple - two sheets of glass, between which there is an insulating gasket that holds them at some distance from each other. The air cavity that has turned out between them creates a certain barrier to the leakage of heat from the inside and the penetration of cold from the outside. At the same time, the transparency of such a system is very high, even higher than that of a traditional double window.
