Fibreboard is made of defibred and highly compacted wood mass and is made of the so-called wet technology. The fibers are arranged in different directions in order to ensure the even quality and strength characteristics within the board, regardless of the direction of the load. As a result of the high pressure and the high pressing temperature, the structure of the board is therefore more compact. Fiberboards are available in two versions: hard T - pressed and thermally tempered, and porous P - not subjected to these processes.
Fibreboards are characterized by homogeneity of the material and, consequently, high mechanical strength and bendability. The production technology allows for large-format boards. The finished material also has high rates of thermal and acoustic insulation. The low price is also a big advantage of the boards. The boards are available in two formats: 1220 x 2440 and 1220 x 2750mm. Thickness of hard boards in mm: 2; 2.4; 2.8; 3.2; 4.0; 4; 5; 5; 5.5; 6; 6.4. Thickness of porous boards in mm: 6; 7; 8; 9; 9.5; 12; 12.5; 15; 16; 19
