We import a special lighter density MDF which is lighter than the MDF currently being sold in the US market. This MDF is made from plantation softwood (Radiata Pine in New Zealand), FSC® and ULEF/CARB P2 certified for the North American market. Some applications where special light MDF would excel at are kitchen cabinet, cabinets for mobile home, trailers and boats where weight is a major concern.

Why Daiken Tatami?

Tatami is a Japanese unique culture never seen in other countries in the world.

Traditionally, Tatami is composed of a board made of straw and surface covered with woven Igusa(Rush straw). However, Tatami made of "Rush straw" have some disadvantages such as causing discoloration, abrasion, and tick exposure.

DAIKEN developed a new material of Tatami using Japanese woven paper. This surface has a high performance which includes resistance to ticks, mold, climate, water, and abrasion.
