SL 97 bi-folding door
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
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, which may enable the system to meet passive house standards.
Natural and durable protection for your living space: the aluminium covers protect the timber profiles outside while the wood remains visible on the inside.
