Bi-folding door SL 97
Laminated wood profiles, a building depth of 96 mm and triple glazing resulting in a U-value of 0.80 W/m²K may enable the system to meet passive house standards

Natural and durable protection for your living space

The wood and aluminium SL 97 bi-folding door is available as a bottom-running or top-hung system. It is particularly notable for its excellent thermal insulation. Laminated wood profiles with a building depth of 96 mm, an additional level of insulation, and triple glazing result in a U-value of 0.80 W/m²K, and enable the system to meet passive house standards. A wide range of opening system variants is available. The system has three sealing levels to provide shelter from the wind and rain, while the aluminium covers on the outside protect the wood profiles from weathering.
