Passivhaus-certified windows are considered among the best on the market as they are fully integrated into the building envelope, thus ensuring greater energy savings thanks to the thermal insulation they provide.
This creates a more comfortable indoor environment, as it significantly reduces condensation, humidity and mould growth.
To obtain Passivhaus certification from the prestigious Passivhaus Institut in Germany, windows undergo rigorous and demanding thermal insulation tests. For a window to be Passivhaus certified, it must have a thermal transmittance coefficient of 0.8 W/m²K or less and a solar factor of more than 50%.
Replus PH-certified windows achieve a thermal transmittance coefficient of up to 0.66 W/m²K, making them some of the best windows on the market.
