Metal strips are hidden inside the profile and act as a strength enhancer. Sometimes windows of a similar design are called metal-plastic, which is more true than just plastic or PVC. The function of metal inserts is very important to ignore.
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.
Decorative possibilities of profiles The characteristic white color of metal-plastic windows is becoming less and less popular. It is replaced by a variety of colors that imitate precious wood species or simply monochromatic according to the RAL scale or other color fans of leading paint manufacturers. Decorating the profile somewhat increases the cost of the finished assembly - the difference can reach 15 - 20%.
Among the advantages of contacting us: a guarantee for windows - 10 years; short terms of production of the order; production of raw materials in the EU; loyal rates; the possibility of obtaining an installment plan; professional turnkey installation.
When you buy a window, especially a laminated window, you must definitely find out about the presence of a profile. If it is not there, then when heated by the rays of the sun or in cold weather, the frame will deform. This will not lead to the destruction of a double-glazed window or the window itself, but a violation of the sealing and difficulty with closing will certainly appear.
It is because of the poor quality of fittings that buyers of PVC windows face the following problems: jamming of the sash; opening the window only with effort; blowing due to the inability to tightly close the sash; creak.
Exprof Aero windows are equipped with a more modern and efficient supply ventilation system - intra-profile. The solution that provides a continuous supply of fresh heated air through the "maze" of channels inside the profile is a patented development of the company. Such a system eliminates the occurrence of drafts, the penetration of noise and ensures maximum energy efficiency of the window in winter.
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.
Silicone The most resistant of all sealants. It does not give in to abrasion, is indifferent to frost and heat, is sufficiently resistant to the chemical components of urban air and detergents. But its price exceeds TPE and it is quite difficult to buy it, except to order it from a company that sells and installs metal-plastic windows and doors.
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.
