Structure, insulation, and substrate all in one panel! Wood-based structural insulation panel "DSP"
Large space with roof insulation! Wooden roof "Double Shield Panel (DSP)" compatible with mixed structures.
The wooden structure insulated composite panel "Double Shield Panel (DSP)" is a structural insulated panel that sandwiches expanded polystyrene (EPS) as the core material between structural surface materials made from laminated hardwood chips (OSB). It is widely used in mid-rise and large-scale buildings, achieving large open spaces by providing insulation through the roof. 【Features】 ○ Short construction period: Simplified processes make it easy to construct ○ High strength: No intermediate support required for spans over 5m ○ Large spaces: Easy to handle regardless of construction method ○ High insulation and fire resistance: Insulation is provided through the roof, not the ceiling / certified for quasi-fire resistance according to regulations ○ Environmental consideration: Obtained F☆☆☆☆ certification This property has achieved a "ZEB Ready" rating in the BELS evaluation by adopting Double Shield Panels and high-efficiency air conditioning equipment, contributing to a decarbonized society.
