Easy Damp Panel (Floor Panel) System

Due to the absence of large beams and joists, injuries and fatigue when stepping over large beams are reduced. The flooring installation can be done by craftsmen other than carpenters without specialized knowledge.

The "Raku Dan Panel (Floor Panel) System" is a construction method for floors that integrates structural plywood, structural LVL, and insulation materials into a single floor panel, allowing for reduced construction time and high insulation performance. Installation is simple, requiring only one steel post for each floor panel. The components that create thermal bridges under the floor are minimal, resulting in excellent insulation properties. Since there is no need for additional construction such as beams or beam connections, this significantly reduces work time and also contributes to reduced fatigue and lower risk of injury. 【Features】 ■ Reduces the amount of insulation material used in the floor by approximately 20% (based on our calculations) ■ Achieves about a 50% reduction in construction time (based on our tests) ■ Minimizes on-site processing, reducing the burden of waste disposal costs *For more details, please refer to the materials available by downloading the catalog. Feel free to contact us with any inquiries.
