FAQ

Frequently asked questions about windows

BUDVAR PVC windows reach very low Uw values: T-Perfekt from 0.69 W/(m²K), the passive T-Energy system from 0.57 W/(m²K). All BUDVAR triple-glazed systems meet high energy efficiency requirements for new builds and renovations — including low-energy and passive house standards.
Class S is a weather-resistance certificate for PVC windows, issued by the independent German institute SKZ — TeConA GmbH. It confirms that profiles keep their shape, colour and tightness even after many years of exposure to sun, frost and moisture. All BUDVAR windows hold the class S certificate.
Titanium Technology is BUDVAR’s proprietary window profile, enriched with a titanium compound in the PVC mix. The profile therefore offers higher rigidity, better thermal insulation, more gloss and colour stability. Since 1992 BUDVAR has been one of the few European manufacturers designing and producing their own window profile.
T-Classic is a versatile system with a good price/performance ratio (Uw from 0.84 W/m²K) — the most popular choice for replacing windows in existing buildings. T-Perfekt is the energy-saving triple-glazed version (Uw from 0.69 W/m²K). T-Energy is the premium passive system (Uw from 0.57 W/m²K) — for passive and near-zero-energy houses.
BUDVAR aluminium windows reach a Uw value from 0.70 W/(m²K) in the passive MB-86N SI system with triple glazing and additional foam thermal inserts in the profile chambers. All systems — MB-79N (Uw 0.80), MB-79N US (0.81) and MB-86N SI (0.70) — meet high thermal insulation requirements and suit energy-efficient houses and passive construction.
A thermal break is an insulating element made of glass-fibre-reinforced polyamide placed between the outer and inner part of the aluminium profile. It interrupts the thermal bridge, allowing modern aluminium windows to achieve insulation comparable to PVC (Uw from 0.70 W/m²K). All BUDVAR aluminium windows have a built-in thermal break.
