Okna PVC


PVC, i.e. polyvinyl chloride, is a modern all-purpose material.

Presently everyone can see it and constantly deals with it. We wear things containing PVC (trainer shoes, outerwear), we drink water supplied by PVC piping, we use plastic-cased appliances (cookers, vacuum cleaners, radios, TV sets). We also drive cars with lots of plastic components, and – looking into the wallet – we can see ... credit or debit cards – made of PVC, too.

PVC, i.e. polyvinyl chloride, is a very good material particularly suitable for windows. PVC window profile systems have been constantly perfected for years and now they are of very high quality so they successfully compete with windows made of other materials. PVC  windows made by BERTRAND are aesthetic and functional, very durable, weatherproof, effectively soundproof, heat retaining and energy-efficient, healthy as well as easy to operate and maintain. Modern PVC windows are very tight which is advantageous in respect of heat retention and soundproofness. Robust and stable profile, high quality seal, highly adjustable fittings and professional assembly guarantee nearly full tightness of our windows.

BERTRAND windows enable isolation from the ambient noise thus the rest in complete privacy. Normally, PVC windows by BERTRAND ensure good soundproofness at the level of Rw = 32 dB. For locations where the ambient noise is loud (near busy streets, airports or other onerous sources) we suggest special panes of increased soundproofing characteristics ranging from 34 to 51 dB.
We normally make PVC windows and doors in white and, upon request, surfaced with woodgrain finish or stained with acrylic glass. Smooth surface of the profiles facilitates the care of them. Crystal clear pane allows for very light exploitation and does not have the so called „dirty curtain effect”
