The dimensions of double-glazed windows (glass thickness) also affect the final characteristics of the entire structure. Noise protection will be higher if the outer glass is thicker than the others.

Choosing windows for a private house When answering the question of how to choose windows for a private house or cottage, one cannot fail to note the importance of having energy-saving qualities. To save on heat carriers in the winter season, it is necessary to give preference to multifunctional double-glazed windows. The chambers of such a window are filled with an inert gas. This means that in winter the double-glazed window will keep heat inside the house, and in summer it will not let the street heat into the room. Such a window will cost more than usual, but the costs will justify themselves in the first season.

Order a free call Selecting the type of sash opening When choosing plastic windows, you should decide on the type of sashes. They determine the functionality of the design and comfort during its operation. The type of sashes must be selected depending on the size of the structure, how many windows are in the room and whether there is a need for regular ventilation.

Important! The reliability of the entire structure depends on the type of profile. They are made of PVC and at first glance look the same. Thermal insulation is provided by internal air chambers, and metal reinforcement guarantees strength. The higher the profile class, the greater the thickness of the outer wall.

Profile A. External wall thickness from 2.8 mm, internal - from 2.5 mm. The best profile for residential buildings. Profile B. External walls from 2.5 and internal from 2.0 mm. Suitable for installation in heated and unheated rooms. Less resistant to mechanical stress.

More than 5 cameras can be found in quality products of well-known brands, but already 7 cameras are a clear overkill. Studies have shown that with a noticeable increase in weight, thermal conductivity begins to increase - it is not the volume of the air gap that comes first, but the thermal properties of the wall partitions, which conduct heat better than air.

The stability of geometric shapes, the preservation of angles, the overall strength of the structure largely depends on the thickness of the partitions inside the frame. It is difficult to check the jumpers, one can only hope for the veracity of the information indicated in the product passport. This is another fact in favor of choosing windows from large manufacturers - the process is well established there and no one will falsify products, risking damaging their reputation and incurring millions in losses.

PVC used for the production of profiles has a number of features that manufacturers are constantly struggling with: 1. Sufficiently high linear expansion, reaching several millimeters per meter of length. In order to compensate for this phenomenon, it is necessary to leave special gaps, use reinforcement and correctly calculate the number of fasteners. The same feature of the PVC profile limits mamaximum dimensions of window structures. 2. Low coefficient of elasticity, but even at the factories it is leveled by the use of metal inserts and the correct calculation of the thickness of the inner walls, which are stiffeners. 3. Insufficient temperature stability and UV resistance. Manufacturers also learned to deal with this drawback by introducing special modifiers and stabilizers into PVC, which preserve the color and structure of the material. In high-quality windows, such additives serve no less than the entire structure. They are, in most cases, completely harmless to humans. But if the frame emits a pungent smell that does not disappear for a long time, do not buy this window. It used lead or cadmium, or even more dangerous chemicals, instead of harmless zinc and calcium.

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.
