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 mounting thickness of the exprof Aero breathable window frame is 101 mm. This is the optimal size to ensure a high level of noise and heat insulation even for three-chamber profiles, as well as high-quality ventilation with closed doors.
The window selection procedure is based on a number of criteria that guarantee the user: reliable protection from external noise (which is important for apartments in a metropolis) energy efficiency; protection from rain, wind and cold; protection against unauthorized intrusions; ease of use; durability (at least 10 years).
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.
You should make sure that the seller has a certificate for PVC windows, you can additionally request certificates for the profile and other components of the window unit.
Why plastic windows are better Hermetic design prevents heat loss, which is especially important in houses with insufficient heating system capacity and apartments in which heating appliances are equipped with meters and temperature controllers.
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.
Decorative possibilities of profiles The characteristic white color of metal-plastic windows is becoming less and less popular. It is replaced by a variety of colors that imitate precious wood species or simply monochromatic according to the RAL scale or other color fans of leading paint manufacturers. Decorating the profile somewhat increases the cost of the finished assembly - the difference can reach 15 - 20%.
Fittings Window fittings are not only a handle, but also all the mechanisms located around the main sash, responsible for its movement, fixation incertain provisions.
Wooden frames, as an alternative, also cannot be called an example of environmental friendliness. In their production, glues, impregnations, varnishes and paints are used, often with a dubious composition.
