Energy-efficient windows compliant with WT 2021
WT 2021 requirement — the same high insulation standards also apply to windows being replaced in existing buildings if the owner intends to take advantage of funding programmes such as „Czyste Powietrze (Clean Air programme)".
For those seeking proven solutions that fit perfectly within the standards of WT 2021 and the programme „Czyste Powietrze (Clean Air programme)", we created the BUDVAR T-Perfekt window line — in an energy-efficient specification, ready for installation in new buildings and during thermal upgrades.
