OSB Airstop

OSB Airstop core is OSB Superfinish described by EN 300 standard as OSB/3 type (load-bearing board for use in humid conditions). It is formed by a special press with high temperature and a phenol-based film applied on the unsanded OSB board. It reduces the differences in the boards’ heterogeneity therefore giving the precise defined values of airtightness and vapor resistance. In the diffusion-open structure this allows for installation of reinforced sheathing, airtight barrier and vapor check at once. OSB focuses closely on the needs of current construction trends of modern low-energy and, in particular, passive wooden houses which have higher requirements for airtightness of external building envelope.
