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.
Window profiles are produced according to EN 12608 SR (Europe) and GOST 30673-99 (Russia). According to the main indicators, they are almost identical. The main parameters are the thickness of the walls of the outer contour and internal partitions. According to these indicators, the profile is divided into three types - "A", "B" and "C".
Three-chamber double-glazed windows are rarely used in PVC windows, as they are too thick and heavy. Modern technologies make it possible to achieve comparable indicators of thermal and noise protection in simpler ways.
Polyvinyl chloride itself for windows was not chosen by chance. This synthetic material is distinguished by: high weather resistance; low coefficient of thermal conductivity; low cost of production; environmental friendliness; excellent adhesion to most types of paints and varnishes; durability (at least 50 years of preservation of the main properties); weak conductivity of sound vibrations.
We recommend choosing plastic (PVC) windows in which the air chambers between the panes are filled with argon or krypton. This design will significantly save the cost of heating in winter and air conditioning in summer.
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.
Profile drainage holes Thermal insulation properties of the window depend on the number of chambers. There must be at least three of them for cold glazing of balconies, loggias and technical rooms and at least 5 for windows of residential premises, offices, retail establishments, hospitals and schools. PVC profile with 3 chambers PVC profile with 3 chambers. PVC profile with 5 chambers PVC profile with 5 chambers.
What you need to know about double-glazed windows Expert's recommendations on how to choose a plastic window will certainly touch on double-glazed windows, as one of the most important parts. Like the frame, a double-glazed window is responsible for the level of thermal insulation and noise protection, but, in addition, the level of light transmission depends on the quality of the glass, which is the main function of the 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.
Pay special attention to seals - layers of elastic material along the edges of the profile. It is desirable that they are not tightly attached to the PVC profile, and they can be changed. Otherwise, in case of damage to the seals, you will change the entire profile, and this will cost you much more.
