Energy-efficient windows meeting WT 2021
The WT 2021 requirement — the same high insulation standards also apply to windows replaced in existing buildings if the owner plans to use subsidy schemes such as “Czyste Powietrze” (the Clean Air programme).
For those seeking proven solutions that fit perfectly within the WT 2021 standards and the “Czyste Powietrze” (Clean Air) programme, we created the BUDVAR T-Perfekt Reno window line — in an energy-efficient specification, ready for installation in new buildings and during thermal upgrades.

Choose the right glazing for your needs
The glass is a key part of any window — it shapes thermal insulation, sound insulation and security. We offer 11 patterned designs as well as functional glazing (absorptive, reflective, sound-reducing, toughened and laminated).
