The reinforcing element of the window is a U-shaped or square profile, which is inserted into the largest chamber located in the center. The thickness of the sheet metal from which the profile is formed is in the range of 1.5 - 2 mm. It is made of galvanized steel and is highly resistant to corrosion. An amplifier is installed in almost all structures, although according to the standards, with a frame length of less than 0.8 m, it can not be used.
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.
1. The dimensions of the double-glazed window. The widespread use of plastic windows with double-glazed windows necessitated their unification and standardization. Currently, bags are produced in thicknesses of 24, 26 and 32 mm. Profiles of different manufacturers have different seats, so you should choose a double-glazed window, in accordance with this parameter.
Profile A. External wall thickness from 2.8 mm, internal - from 2.5 mm. The best profile for residential buildings. Profile B. External walls from 2.5 and internal from 2.0 mm. Suitable for installation in heated and unheated rooms. Less resistant to mechanical stress.
Intra-profile ventilation of PVC windows The method of ventilation of a room with closed sashes can be implemented in different ways. Some manufacturers install a slotted, folded or overhead ventilation valve in the PVC profile.
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.
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.
The role of air chambers in PVC windows Closed longitudinal air chambers in window frames play a dual role. This is an effective thermal insulation and reinforcement of the structure. External chambers, in addition, serve to remove condensate that forms inside the cavity due to the temperature difference in the room and outside. They are connected to the atmosphere at the bottom and drops of water simply flow down to the street. The presence of such holes has practically no effect on the overall level of thermal insulation.
After an approximate calculation on the site, you can choose the nearest offices where you can purchase the company's products, and send them an application that will take into account all the parameters you have chosen.
The more chambers, as well as the distance between their walls, the higher the noise performanceo- and thermal insulation. Two-chamber profiles are intended mainly for cold glazing, unsuitable for windows in heated rooms due to low thermal insulation.
