Abstract (en)

The board has a middle layer made of a mixture of derived timber material i.e. wood chips or wood fibers (2), and foamed natural material (4) i.e. foamed plastic. The foamed natural material is selected from corn, rice, wheat or a mixture of corn, rice and wheat. The derived timber material of the middle layer exhibits smaller density than derived timber material of an outer layer. The middle layer includes filament-like reinforcing fibers (5), which are made of carbon or glass fibers. The middle layer includes latent heat storage units to increase heat storage capacity. An independent claim is also included for a method for manufacturing a derived timber material board consisting of three layers.
