TPE seal Flexible thermoplastic (TPE) seals are one of the most widely used seals due to their ability to be used on automated assembly lines. It is very convenient for welding, easily changes its shape when compressed by the sashes, quite firmly fills the junction area and seals the window under normal operating conditions.

Frame profiles are slightly different. There are separate designs for bearing racks, sashes, crossbars). In any case, profiles from one manufacturer are used for one window, which are cut at the factory to the required length and assembled into one structure. The elements are connected by special welding or mechanical hardware.

The surface of the profile is painted in various ways - acrylic coating, spraying, lamination under pressure. More expensive designs use metal or wood plates that are firmly fixed to the outside or inside of the frame. The decoration also concerns the very shape of the profile - the flat frames that have become familiar are gradually being replaced by rounded or more complex relief.

Among the advantages of contacting us: a guarantee for windows - 10 years; short terms of production of the order; production of raw materials in the EU; loyal rates; the possibility of obtaining an installment plan; professional turnkey installation.

Which package is installed on the window largely depends on the seat on the frame, especially on one characteristic - the depth of the package. In good windows, the outer glass should be at least 15 mm from the front edge of the frame, which are overlapped by the profile rebate. For a mounting depth of the frame of 50 -70 mm, the seat of the double-glazed window ensures this distance is at least 18 mm. Few people pay attention to this parameter when buying, concentrating on the number of cameras and the width of the frame, but for heat-shielding properties it is very important - the smaller the seating depth, the faster the glass will start to freeze and mist.

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.

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.

Metal strips are hidden inside the profile and act as a strength enhancer. Sometimes windows of a similar design are called metal-plastic, which is more true than just plastic or PVC. The function of metal inserts is very important to ignore.

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.

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.
