PVC
PVC contributes to increasing the heat in the premises, because the polyvinyl chloride has lower heat transfer coefficient.
PVC joinery requires minimal maintenance – no need to paint, treat with special preparations, just cleaning with soft cloth and soap.
PVC joinery requires less investment, which makes it cheaper than aluminum.
German and Austrian joinery has been tested on the Bulgarian market for 10 years now, and it establishes itself as an optimal correlation between price and quality. The company works with German, Bulgarian and Austrian profiles from the branches TROCAL, KBE, VEKA, BLICK PROFILING, WEISS PROFIL, KMG, 3, 4, 5 and 6 chamber profiles.
Glazed windows
Due to their design, new windows make you feel cosily.
The joinery is offered with glazed windows, which is a key element of the window. It is a set of two or more lites of glass, hermetically sealed to form a single glazed unit. Thus, between the glasses is formed hermetically sealed space, which doesn’t allow pollute air to come in it.
Glazed windows increased heat and soundproofing insulation, the degree of insulation depends on the type of glass. The necessary index for heat insulation can be reached by special glasses with low-emissivity coating. Low-emissivity glasses– so called K-glasses lower the total heat flow thorough the window. They are opaque to infrared radiation. Thus, in the winter is warm in the room, and cool in the summer.
When the glazed windows are made from two ordinary glasses, it reaches heat transfer coefficient 2.9 W/m2k. Glazed windows made from white and K-glass have heat transfer coefficient 1.7 W/m2k.
