The excellent results of the Uf coefficient (heat transfer coefficient for the frame), confirmed by tests at IFT Rosenheim and the basic glazing thickness of 48 millimeters, guarantee a thermal transmittance coefficient below the one required for passive houses Uw≤ 0.8 W/m2K. The improvement of these parameters is also influenced by the deeper embedding of the glass during window installation and the improvement of the linear transmittance coefficient ψ. Energy-saving windows for passive houses are made using the latest technology to avoid heat loss. Properly performed installation of energy-saving windows and window sills is a basic element of energy-saving construction, which affects the maintenance of appropriate utility values. In order to meet the expectations of customers looking for doors for energy-efficient and passive buildings, we have expanded our offer with doors made of BLUEVOLUTION 82 and S 9000 system profiles. Both systems, thanks to the use of a third central seal, allow for very high thermal and acoustic insulation parameters. In the case of joinery with high insulation parameters, we recommend professional installation of windows using vapor- and waterproof as well as vapor-permeable tapes. This allows for the elimination of thermal bridges, moisture in the walls of the building and obtaining very high airtightness parameters of buildings. Windows for passive houses should have appropriate parameters, tightness and must be correctly installed to maintain all their features.
