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.

What is the best PVC profile to choose Profiles are divided into three classes: premium, standard and economy. Which windows to choose will depend on the requirements for thermal insulation and the financial capabilities of the customer.

Given the characteristics of glass as a material with a certain rigidity, spatial structures like double-glazed windows are distinguished by certain size restrictions. They can be within a minimum of 300mm on one side and in an aspect ratio of 5:1. But the maximum glazing area should not exceed 3 m2 in a single-chamber package with 4 mm thick glass and 4.2 m2 with 5 mm glass thickness.

Bad products, even if they don't break the window on their own, can fix it in the wrong position or block it when you don't want it to. And they can also creak, annoying the owners of purchased windows with low-quality fittings.

To confirm the serious intentions of the company in which you plan to choose PVC windows, you need to get more information: about the range; about the quality of services; payment letter order.

Rebate distance Is PVC profile wall thickness so important? When deciding which plastic windows are better to choose, it is necessarypay attention to the thickness of the outer walls and partitions. If the outer wall is thinner than 2.5 mm and the inner wall is 2 mm thin, then such windows are only suitable for an unheated garage, warehouse or workshop. In a residential building, they are of little use, in the sense of protection from the cold. In addition, it is possible to assemble a relatively small structure from such profiles - in addition to their low intrinsic strength, the walls do not allow fastening powerful fittings.

Even on dirty seals, it is not recommended to use organic or synthetic solvents. It is better to wash with warm water with neutral household detergents, dry well and lubricate. Of course, silicone oil and glycerin are not a panacea, but they can extend the life of seals by several years.

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.

Number of air chambers in windows Chambers are voids in plastic construction elements (profiles and double-glazed windows). How many cameras should be in a quality window? The answer to this question depends on the climate of the region where you live and the location of the apartment.
