The main characteristics of plastic windows To know which plastic windows to choose, determine the important characteristics of each structural element. Choosing a profile for PVC windows and double-glazed windows in accordance with the climatic features of the living area, the location of the house and apartment will help to acquire a high-quality and warm design that will last for decades. Consider the types of components in more detail.
Instead of standard glass, an impact-resistant triplex (two or more layers of glass with a polymer film fixed between them), glass with a multilayer coating that blocks part of the sun's rays can be installed in a double-glazed window.
What technical characteristics of the PVC profile should be taken into account The term "profile" in relation to plastic windows and doors means the material from which the frames and sashes are made. For vertical and horizontal elements in PVC windows, a complex structure made of metal (aluminum or steel) and polyvinyl chloride is used. In cross section, it presents several longitudinal cavities separated by sealed walls. Such cavities are called chambers, the more of them, the theoretically better - the windows become warmer and stronger.
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 else to look for when choosing plastic windows We talked about the main parameters of window structures - they should be taken into account when choosing in the first place. However, there are other characteristics that you should pay attention to in order to choose the best option in terms of thermal protection, sound insulation, durability and ease of use.
The ends of the double-glazed window are sealed, the air inside is dry and the glass does not fog up at any temperature inside and outside. In modern double-glazed windows, instead of air, an inert gas is sometimes pumped, most often argon. Its thermal conductivity is somewhat lower than air, but the cost is higher. Whether such a step is justified in terms of energy saving is still a matter of debate. But in relation to the price - manufacturers win unambiguously.
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.
For protection, comfort and beauty: how to choose plastic windows correctly The choice and purchase of metal-plastic windows requires the utmost responsibility, since the installed design provides for a fairly long service life - NOT a year or two, but decades! The modern market is replete with offers from both well-known and beginners offering ready-made engineering solutions, including non-standard ones.
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.
