A modern house cannot be imagined without plastic windows, and when it’s time to buy them for ourselves, we face a choice between products from different manufacturers. All it looks like, so it can be difficult to determine – if you do not know how strong the differences in exploitation can be. There will be useful tips from experts who suggest which criteria should be used when buying plastic windows.
Classics are polyvinyl chloride (PVC) reinforced with steel reinforcement, resistant to temperature changes and capable of serving more than 50 years, absolutely safe for human and animal health. PVC profile should be free from external defects, unevenness and chemical odor.
60 mm is suitable if you want to satisfy basic needs in heat, silence, comfort. A profile of this width prevailed in all markets in the 1990s: these are the same euro windows that by the way came to replace outdated wooden structures. The 60 mm width profile is suitable for single glass 4-10 mm thick or insulating glass up to 32 mm thick, often single-chambered. The white upvc windows in Kent are there now.
70 mm increases the performance by 30% compared to 60 mm. Suitable for almost any climatic conditions and has until now been the most common in Russia. Suitable for double-glazed units up to 40 mm thick with energy-saving, sun-protective or combined coatings, bulletproof and fire retardant composite glazing.
From 80 mm at the moment gives the maximum technically possible performance indicators, which exceed the regulatory requirements for all regions of the Russian Federation with a large margin. Since the end of this year, they have become more affordable for the Russian buyer in terms of production time and price, than before (the system was recently mastered by REHAU). Profiles with a width of 80 mm and more allow the installation of double-glazed windows up to 50 mm thick.
Cameras with air are designed to preserve heat and silence. The more of them – the warmer and quieter it will be in the room. The most common modern models of plastic windows – with 3 and 5 cameras, but in general there are up to 8 of them. The choice depends on your living conditions: in a relatively warm climate on a window facing a quiet street, you can confine yourself to a design with a small number of air chambers, and vice versa.
Double-glazed windows are two or three glasses fastened together by remote frames into one or two chambers (depending on this they are called 1-chamber or 2-chamber). In Russia, single-chamber double-glazed windows are usually found from two sealed glasses, but in the cold northern regions this option may not be enough. Large manufacturers offer warmer systems.
