Untreated cedar flat structural material "KOUMUKU"

Structural horizontal components made of solid cedar wood that respond to social needs such as SDGs, suitable for underfloor areas!

We would like to introduce our solid cedar horizontal structural material "KOUMUKU." We conducted a demonstration experiment on the horizontal structural surface of cedar boards and obtained official data showing a floor amplification factor of 1.15, enabling the assurance of seismic performance based on clear evidence. This is made from domestically sourced solid cedar wood and can be used as a subfloor material for homes that prioritize natural materials, as well as a replacement for traditional plywood subfloor materials. 【Features】 ■ Conducted a demonstration experiment on the horizontal structural surface of cedar boards and obtained official data showing a floor amplification factor of 1.15 ■ Enables the assurance of seismic performance based on clear evidence ■ Made from domestically sourced solid cedar wood ■ Can be used as a subfloor material in place of plywood subfloor materials *For more details, please refer to the PDF document or feel free to contact us.
