PVC windows have recently appeared on the market, the cavities of which are not filled with air, but are filled with foamed heat insulators - expanded polystyrene, for example, or filled with fiberglass materials. Even with a relatively small number of chambers, their thermal insulation characteristics are much higher than air ones. But for now, their price is also higher.
Reinforcing insert Reinforced windows are stronger and more durable. Reinforcement is an essential component of a high-quality translucent structure. It is necessary so that the windows can resist wind loads, and also do not deform due to thermal expansion. This is especially true for regions with significant temperature fluctuations throughout the year.
Modern wooden windows are equipped with durable "warm" double-glazed windows, they look aesthetically pleasing, but have a couple of significant drawbacks: high price and the need to update the coating.
The properties of the double-glazed window determine the heat and sound insulation of the window block, as well as the degree of natural light in the room. Fittings play an important role in the usability and durability of the translucent structure. Details such as constipation, clamp, scissors, handle, bar are responsible for the possibility of opening the sashes in different ways.
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 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.
Profile drainage holes Thermal insulation properties of the window depend on the number of chambers. There must be at least three of them for cold glazing of balconies, loggias and technical rooms and at least 5 for windows of residential premises, offices, retail establishments, hospitals and schools. PVC profile with 3 chambers PVC profile with 3 chambers. PVC profile with 5 chambers PVC profile with 5 chambers.
Wooden frames need periodic updating of the paintwork, maintenance of PVC windows is not required. And plastic windows are easier to clean than wooden ones.
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.
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.
