Coloured windows and doors have a special role to play when it comes to façade design. They enhance the visual appeal of buildings, and are one of the first things people notice.

Today, passive house windows can be manufactured efficiently and cost-effectively using state-of-the-art PVC profiles and ...

Glazing windows with low-emissivity glass should become the standard, because they can save 60-70% of heat that is lost through the glass.
