Construction board and method for manufacturing a construction board

摘要

The building board comprises a core (1) consisting of glued and compressed together wood chips or wood fibers, and two cover layers (2,3) covering the core on the upper and lower sides, wherein the core is scattered in multi-layered fashion and the cover layers consist of a scattered wood-plastic composite (WPC) material. The plastic portion of the cover layers is between 20 and 80 per cent. The apparent density of the building board is greater than 500 kg per cubic meter, and may be between 500 and 700 kg per cubic meter. An independent claim is included for a method for producing a building board.
