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 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.
But in slightly more extreme circumstances, such as severe frost or heat, as well as direct sunlight (UV), it can fail. Becoming brittle in the cold and softening in the heat, it quickly becomes unusable if the window sash is actively used. But with the doors constantly closed (or constantly ajar, in micro-ventilation mode, for example), it will last quite a long time.
There are several basic modifications of seals that differ in some properties and, of course, in price. The most common are: Thermoplastic (TPE). Thermopolymer (EPDM). Rubber. Silicone. Let's consider them in more detail.
Choice of accessories and equipment When choosing accessories for windows, you should pay attention to their material, colors and functionality. You can choose metal-plastic windows and order roller shutters, blinds, mosquito nets for them. If necessary, window sills, slopes and ebbs can be added to the package.
Most of them are made on the basis of high-quality float g

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.
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 quality of the product is guaranteed by the reputation of the manufacturer. Among the cult types of fittings are products of the following brands: MACO (Austria) - high protection against premature wear and corrosion due to wax and anti-corrosion spraying Winkhauz. Represented by a wide range of rotary, sliding, combined systems, handles, locking devices, hidden elements; ROTO (Germany) - zinc coating is used for corrosion protection. High load capacity (sashes can withstand a weight of about 150 kg), a wide range of designer handles, locking systems, opening modules, etc.; REZE. (Turkey). Docking system of connections for convenience of installation. Burglary resistance. Aesthetic appearance. Recommended for completing windows installed in rooms with high humidity.
