A wooden structural panel system that supports a comfortable space with "high seismic resistance," "high thermal insulation," and "high durability"!
"Pre-Wall" has achieved not only "earthquake resistance" and "thermal insulation" but also an open "large space." By combining the true wall sandwich structure and monocoque structure, it absorbs external loads across the entire surface, demonstrating high earthquake resistance. With the adoption of phenolic foam, which boasts top-class thermal insulation performance, it creates a comfortable living environment that is unaffected by the winter cold. [Features] ■ High earthquake resistance - Fusion of traditional construction methods and 2x4 methods - High earthquake resistance achieved through the uniquely developed "true wall sandwich structure" - Design possible with wall multipliers of 3.3 times and 5 times - Minimal reduction in strength after the second occurrence, making it strong against repeated earthquakes *For more details, please refer to the PDF materials or feel free to contact us.
