Window frames

Window frames are a key component of high-performance windows, whether operable or fixed, single or multi-part units. In addition to carrying structural loads and ensuring airtight operation, the frame protects the glazing edge bond and contributes to the durability and long-term performance of the insulated glazing unit. Thermally optimized window frames with low Uf-values reduce heat loss and minimize thermal bridges at the glass edge and at junctions with the wall. Properly designed frames allow the insulation layer of the building envelope to continue seamlessly around the opening, supporting high interior surface temperatures, improved thermal comfort and condensation-free performance in energy-efficient and Passive House buildings.
