Wooden structure insulation panel "Double Shield Panel (DSP)"
Adopted by Rugby School Japan! A large space with a wooden roof that accommodates mixed structures using the "Double Shield Panel (DSP)"!
The wooden structure insulation composite panel "Double Shield Panel (DSP)" is a structural insulation panel that sandwiches expanded polystyrene (EPS) as the core material with structural surface material (OSB) made from laminated hardwood chips. It is widely used in large-scale buildings and achieves large spaces by insulating the roof. 【Features】 ○ Short construction period: Simplified processes make it easy to construct ○ High strength: No intermediate support required for spans over 5m ○ Large space: Easy to handle regardless of construction method ○ High insulation and fire resistance: Insulation is applied to the roof rather than the ceiling / Certified for quasi-fire resistance according to regulations ○ Environmental consideration: Obtained F☆☆☆☆ rating This property has achieved a "ZEB Ready" rating in BELS evaluation by adopting Double Shield Panels and high-efficiency air conditioning equipment, contributing to a decarbonized society.
