Competent installation remains an important aspect, so only qualified specialists should trust the installation of windows. To determine the ideal, it is necessary to understand in detail the features of the materials used in the manufacture of metal-plastic windows.
There are no completely low-quality windows on the market now - there are a lot of companies offering windows of their own production and only one-day firms can afford to work with cheap materials. Before ordering windows, you need to find out as much as possible about the company's reputation, see its products, etc. It is best to buy products from large manufacturers - high-quality equipment plays a lot in the manufacture of windows. Many small companies and workshops cannot afford to buy expensive cars, and therefore their products are somewhat worse.
On the market you can also find windows with a trapezoidal section of the front part of the frame, the so-called "Dutch" or "Danish". Their installation depth exceeds 100 mm and often they do not require the installation of external slopes, completely blocking the opening. Such windows are more efficient than conventional rectangular ones, but they are also more expensive.
If you see that the glasses in the double-glazed window are not parallel to each other, you can no longer buy a window. The same applies to all kinds of seals: they should fit snugly against the glass, there should not be any gaps. Sometimes the distance bar inside is designed for three glasses, although there are only two of them in a double-glazed window - this also worsens the characteristics of the double-glazed window and reduces all heat retention by the window to zero.
Choosing a PVC window seal Tightness is one of the mainof plastic windows. It is achieved by using special sealing elements that are laid around the perimeter of the doors and prevent the penetration of moisture and cold from the street and the escape of heat from the side of the house. In addition to these functions, the seal is also a good sound insulator, not inferior in terms of sound reduction to the best double-glazed windows.
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.
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.
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.
In addition to energy efficiency, good sound insulation and comfortable lighting are important in the house. Plastic windows must be equipped with protective elements to prevent burglary attempts from the outside.
The window sill and slopes are not structural elements of the window block and are decorative details. Design features of Exprof windows Correct plastic windows must be equipped with a ventilation mechanism to ensure a constant supply of fresh air into the room, an optimal level of humidity and a healthy microclimate. The frame of exprof Aero breathable windows has a built-in ventilation chamber designed to let in and heat air from the outside while maintaining tightness, heat and noise insulation of the structure.
