On the market you can also find windows with a trapezoidal section of the front part of the frame, the so-called "Dutch" or "Danish". Their installation depth exceeds 100 mm and often they do not require the installation of external slopes, completely blocking the opening. Such windows are more efficient than conventional rectangular ones, but they are also more expensive.
Profile C. The so-called object (object). As a rule, the wall thickness is not standardized, but less than that of profiles A and B. Such structures are installed in unheated rooms. As a rule, the sashes do not open, the design of the windows is monolithic.
To be convinced of the quality and high consumer properties of plastic windows, you just need to read about their characteristics in the article brought to your attention and compare them with wooden structures. The text is far from advertising in nature - only objective information. The choice of priorities is up to the reader. Here you will learn how to choose plastic windows, and why some designs are better than others.
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.
The seal should be: as flexible as possible; durable; do not lose their properties at low and high temperatures (-20 ... + 55 0С); do not emit odors and toxic fumes; do not change colors over time.
Decoration of PVC profiles Who produces high-quality profiles Basic profiles, from which window structures are assembled, are produced by several dozen factories in Europe, Russia and the CIS countries. Only one name of the manufacturing company can tell you how to choose plastic windows correctly. But as a finished product, a lot depends on the specific window assembler and its installation. Experience suggests that expensive quality profiles, as a rule, are used by responsible performers who produce excellent windows.
Certificate of conformity to GOST 30673-2013 for the profile, test reports for intra-profile ventilation, conclusions of laboratory tests for durability and resistance to climatic influences, as well as other documentation confirming the quality of the exprof profile, you will find in the appropriate section on the website.
Price The total cost of a window unit depends on the dimensions, configuration, requirements for the design of the structure, the complexity of installation and some other nuances.
Choosing a PVC window seal Tightness is one of the mainof plastic windows. It is achieved by using special sealing elements that are laid around the perimeter of the doors and prevent the penetration of moisture and cold from the street and the escape of heat from the side of the house. In addition to these functions, the seal is also a good sound insulator, not inferior in terms of sound reduction to the best double-glazed windows.
All profiles in exprof windows are equipped with reinforcing inserts with a thickness of 1.5 to 2 mm and have a protective zinc coating. Double-glazed window The main characteristics of the element: the thickness of the double-glazed window, the number of glasses and, accordingly, the chambers between the glasses, the presence of special glasses with heat-shielding coating.
