Wood, heat-insulated

A key feature of the SL 78 folding glass door is its excellent thermal insulation. 78 mm laminated wood sections with triple glazing achieve a U-value of 1.1 W/m²K and meet the requirements of the low-energy house standard. Certified wood and water-based varnishes are consistent with our ecological approach to sustainable building. A wide range of colours and wood types ensure maximum creative scope for individual designs.
