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!

The "NLT Container" is a wooden container that uses NLT panels. By converting traditional steel containers to wooden ones, it not only allows people to feel the warmth of wood in various locations but also contributes to a decarbonized society. 【Contribution to Decarbonization】 Our unique joining method minimizes damage during dismantling, making it possible to reuse NLT panels. Of course, since they can also be reused as units, this contributes to resource conservation and reduction of CO2 emissions. 【Improved Workability】 Containers are created in the factory and transported and installed on-site in their container state. Our comprehensive support allows for improved workability. 【Design Flexibility】 Since panels of the same dimensions are used, there is high expandability. Combinations can be made according to scale, such as horizontally or stacked.

A tie-down system called "Rodman" that responds to the pull-out forces of high-strength shear walls in mid- to high-rise wooden buildings. In mid- to high-rise wooden structures, massive pull-out forces accumulate in the lower levels due to horizontal forces such as seismic forces. Attempting to counteract this significant uplift with existing hold-down hardware often necessitates custom, oversized, or multiple placements of hardware, leading to issues such as severe cross-section damage to the wood and poor fitting. "Rodman" is a new original tie-down system developed to smartly address these non-standard pull-out forces and ensure the stability of shear walls in mid- to high-rise construction. [Features and Benefits in Structural Design (Partial)] ■ Improvement in fitting due to miniaturization of hardware on each floor By directly transmitting the pull-out forces from each floor to the foundation, the hardware can be significantly miniaturized. This minimizes cross-section damage to the wood and enhances fitting flexibility. *For detailed product specifications and design manuals, please contact us. *For more information, please download the PDF or feel free to reach out to us.
