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 device of a double-glazed window 1. Remote frames. 2. Glass. 3. Air gap. 4. Moisture-absorbing granulate. 5. Primary circuit sealant. 6. Sealant of the second circuit.Such a double-glazed window is called single-chamber, since there is only one air cavity. If you install another glass on the same gasket (distance frame), you get a two-chamber double-glazed window. Again, the thermal conductivity will be halved, the noise insulation will increase, but the light transmission will decrease by no more than a few percent. When choosing a double-glazed window, it must be remembered that its weight is 30% more than a single-chamber one, naturally, the cost is higher.
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.
For an apartment window in a big city, it makes sense to consider at least a three-chamber profile. For rooms located on high floors, apartments with a poorly functioning heating system, and rooms overlooking highways and multi-lane avenues, five- and six-chamber designs are suitable.
number of chambers in double-glazed windows A single-chamber double-glazed window is more suitable for regions located in a subtropical and temperate climate, houses located in quiet neighborhoods. A double-glazed window is the best choice with the best heat and sound insulation characteristics (provided that the profile is chosen correctly), a universal option for both city apartments and private houses, it can be used not only in temperate, but also in subarctic climates
Many opponents of PVC windows argue that wood is better for translucent structures, as it "breathes". Most likely, these people do not know about the existence of exprof Aero plastic windows, which allow air to pass through when the leaves are closed, providing a normal indoor climate without drafts, freezing and condensation.
What you need to know when choosing pvc windows When you want to buy plastic windows, you get the feeling that they are all the same. White in color, with similar handles, glasses and seals - you just need to say the dimensions and choose those that are cheaper. But in this case there are many nuances that it is desirable to know when choosing a window.
Choosing plastic windows: video instruction from an expert The video contains recommendations for working with a calculator on the exprof website, which will help you select all the important characteristics of a window structure in our configurator and send an application for production.
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.
Availability of certificates For each component of the window (profile, double-glazed window, fittings, components) there is a separate GOST. Manufacturers of materials and products for completing windows must obtain certificates of conformity for their products.
