OSB 3 T&G Ecoboard is a high-performance wood-based panel which complies with EN 300 and EN 13986. It is also available in multiple formats with a tongue and groove profile on all 4 sides or with butt edges, with a Contiface surface (treated, not sanded) or in a sanded surface version. OSB 3 Ecoboard T&G offers excellent results in the construction sector and can be used as a multipurpose panel for structural purposes in roof, wall and floor areas. It can be used as an airtight layer or vapour barrier in a vapour permeable construction, so that the use of additional isolation foil is unnecessary.
