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.

What technical characteristics of the PVC profile should be taken into account The term "profile" in relation to plastic windows and doors means the material from which the frames and sashes are made. For vertical and horizontal elements in PVC windows, a complex structure made of metal (aluminum or steel) and polyvinyl chloride is used. In cross section, it presents several longitudinal cavities separated by sealed walls. Such cavities are called chambers, the more of them, the theoretically better - the windows become warmer and stronger.

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.

What you need to know when choosing fittings for windows Fittings are the last of the three elements that make up modern windows. This is not only a handle, but also a system of mechanisms that open and close windows in one mode or another. The fittings are made of metal alloys, and you should not save on them. The better the material (such as, for example, alloy steel), the easier the fittings work, the less force must be applied when opening / closing the window, and the longer the service life of the products themselves.

The most significant criteria are the recommendations of acquaintances or those who have already used the services of a particular company. The following are taken into account: the company's work experience in the market; staff professionalism; the technologies and materials used in the production (and the certificates corresponding to them) the timing of the production of orders; availability of warranties.

They also do not spoil the appearance of the window - as a rule, the holes are completely invisible or closed with decorative plugs. If it was not possible to find such technological holes on the front of the window, then you have a not very high-quality design that will last much less than the established period.

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.
