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.
Poor-quality elements can also provoke other problems with the operation of a double-glazed window. Sealant Sealant is responsible for a snug fit of the sash of the window structure and noise insulation, the absence of drafts. To choose a sealant for plastic windows, it is enough to know that high-quality sealing rubber or silicone is elastic, pliable, and odorless. To check the quality, you can compress the media and then release it. A good seal is easily pressed through and quickly returns to its original shape, there are no creases on it.
PVC profile filled with polystyrene What affects the width of the profile The correct choice of plastic windows should be based on a comprehensive analysis of their parameters. One of the main ones is the width of the profile, in a professional language - the mounting depth. For standard windows, it is 50 - 80 mm. If the width of the frame barely reaches 60 mm, then there are no more than three cameras in it, and with a depth of up to 70 mm there are four or even 5.
The window sill and slopes are not structural elements of the window block and are decorative details. Design features of Exprof windows Correct plastic windows must be equipped with a ventilation mechanism to ensure a constant supply of fresh air into the room, an optimal level of humidity and a healthy microclimate. The frame of exprof Aero breathable windows has a built-in ventilation chamber designed to let in and heat air from the outside while maintaining tightness, heat and noise insulation of the structure.
You should make sure that the seller has a certificate for PVC windows, you can additionally request certificates for the profile and other components of the window unit.
Compared to wood and aluminum, which are traditionally used for window structures, PVC is also more preferable for aesthetic reasons. It is easy to assemble from it not only rectangular structures, but almost any geometric configuration.
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.
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
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.
Window profile width The wider the profile section (the distance between outdoor and indoor surfaces), the warmer and quieter the translucent structure will be. In a wider profile, you can put a double-glazed window with better thermal insulation and noise reduction characteristics.
