The wooden structure insulated composite panel "Double Shield Panel (DSP)" is a structural insulated panel that sandwiches a core material made of expanded polystyrene (EPS) between structural face materials made from laminated hardwood chips (OSB). It boasts excellent structural strength and is available in sizes up to 1,820×6,000mm, making it widely used in large-scale construction. Its wood usage rate is about half that of conventional wooden structures, contributing to the protection of forest resources. 【Features】 ○ Short construction period: Simplified processes make it easy to install ○ High strength: No intermediate support required for spans over 5m ○ Large spaces: Easy to handle regardless of construction method ○ High insulation and fire resistance: Insulated at the roof rather than the ceiling / Certified for quasi-fire resistance ○ Environmental consideration: Acquired F☆☆☆☆ rating For more details, please contact us or download the catalog.

This document is the "DSP Utilization Facility Edition" of examples of wooden facility construction. It includes examples of DSP utilization such as "House of St. Anna" in Fujisawa City, Kanagawa Prefecture, "Kousaka Country Club" in Higashimatsuyama City, Saitama Prefecture, and "After School Day Service" in Yokohama City, Kanagawa Prefecture. A total of 12 examples are presented along with numerous photographs.

At Kumamoto Aso Airport's passenger terminal building, we have adopted a wooden truss called "Connect Truss," made from cedar sourced from Kumamoto Prefecture, and a wooden composite insulation panel known as "Double Shield Panel (DSP)" for the roof section. It can also accommodate mixed structures◎ A large space can be realized with wood! How about considering the roof structure of a building with "wood," taking into account people and the environment? 【Advantages of Wooden Roofs】 ◆ Does not limit the choice of lower structures ◆ Utilization of domestic materials ◆ Lightweight framework ◆ Contribution to SDGs *We are currently offering a free collection of architectural examples! Please download the PDF to obtain it. Feel free to consult us for detailed specifications and other inquiries.

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 large-scale buildings and achieves large spaces by providing insulation through the roof. 【Features】 ○ Short construction period: Simplified processes make it easy to construct ○ High strength: No intermediate support needed 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 ○ Environmental consideration: Acquired F☆☆☆☆ certification *We are currently offering a free collection of architectural examples!
