OSB
OSB stands for “Oriented Strand Board” and is made from thin veneer strands that are bonded together with a synthetic resin. BOLDERAJA OSB SUPERFINISH ECO consists of three cross-oriented layers with the surface of the board formed from strands oriented along the length of the board and the core strands arranged in cross orientation. This crosswise orientation of the individual layers achieves a high level of dimensional stability and an excellent mechanical performance.
