It often happens that people confuse glass panes and vinyl windows. These are not synonyms, however. A glass pane is a part and nearly crucial part of a window structure. This is a translucent structure consisting of two or more glasses that are fixed (glued) together along the outline using spacing bars and sealant compounds. Main functions of a glass pane: natural lighting, thermal and noise insulation. Glass panes are categorized by manufacturing process: standard, where molecular sieve is poured into a metal or vinyl spacer, after which the glued glass sheets are plastered along the edge with silicon, isomelt, polysulfide or polyurethane sealant compound, thus providing the secondary sealing. Warm edge technology-based manufacture This is a new and promising technology. It differs from the standard technology in that instead of several production steps as in the case with glass pane it involves only two (flexible spacer application, pressing), thus greatly saving time and cost. Such glass pane is warmer than that manufactured using a standard technology. As defined in GOST 24866, glass pane are categorized as follows: by number of chambers. A space between each two glass sheets is called a chamber. Glass panes can be single-chamber (two glass sheets), double-chamber (three glass sheets) and so on. by width The glass pane width is the full width considering its glass and air part. Glass panes can be 14, 16, 18, 20, 22, 24, 28, 32, 36, 40, 42, 44 etc. mm By glass type: regular energy-efficient glass with low-emission coating (hard or soft, also known as - or I-type) noise-resistant triplex sun-screening tinted or film-coated glass shutterproof glass with a high protection class.
