Often the profile is additionally reinforced from the inside for strength, and this is the right move. If the profile is not reinforced, it will fall apart under its own weight much sooner, and you will have to suddenly buy a new window.

Installation depth In addition to their own heat-shielding properties, such frames allow you to install more durable fittings, thick double-glazed windows and additional contours of insulation and sound insulation. But the width of the profile does not necessarily indicate the number of chambers - there are profiles with fewer cavities, but with a width of 8 or even 9 cm. In terms of general thermal insulation properties, they are better than narrow multi-chamber ones - it is not the number of chambers that matters here, but their size and stock air in them. We can conclude that the greater the installation depth, the better the window in terms of thermal insulation and other characteristics.

The product passport must contain all profile parameters, including resistance to low temperatures, or simply indicate the degree of performance. If it is written that the profile belongs to a normal or frost-resistant type, then you can buy without fear, it is designed for negative temperatures.

Wooden frames, as an alternative, also cannot be called an example of environmental friendliness. In their production, glues, impregnations, varnishes and paints are used, often with a dubious composition.

It is because of the poor quality of fittings that buyers of PVC windows face the following problems: jamming of the sash; opening the window only with effort; blowing due to the inability to tightly close the sash; creak.

Modern wooden windows are equipped with durable "warm" double-glazed windows, they look aesthetically pleasing, but have a couple of significant drawbacks: high price and the need to update the coating.

Exprof Aero windows are equipped with a more modern and efficient supply ventilation system - intra-profile. The solution that provides a continuous supply of fresh heated air through the "maze" of channels inside the profile is a patented development of the company. Such a system eliminates the occurrence of drafts, the penetration of noise and ensures maximum energy efficiency of the window in winter.

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.

High-quality translucent structures for many years protect the room from the scorching sun, cold and wind, provide optimal humidity in the room, perform protective and other functions. It is important to know how to choose the right plastic windows for an apartment in order to understand which characteristics you need and which ones are not worth paying for.
