OSB 3 Ecoboard® is a high performance wood-based panel, in accordance with the EN 300 or EN 13986 standard. OSB panels are particularly suitable for constructional applications. The panel structure, consisting of three layers of aligned strands (elongated wood chips), ensures excellent values in terms of modulus of elasticity and flexural strength. The different OSB formats provide the versatility needed for building walls. Together with its water-repellent surface ("Contiface"), this makes it a unique product.
