Suitable for load-bearing applications in humid environments: wall and ceiling sheathing in dry construction, continuous base for asphalt shingles or metal roofing sheets, raised access flooring over battens, rigid support under floating floors, reusable formwork, temporary enclosures, industrial packaging, etc.

Adhesive with water-resistant resin (typically MDI or MUF), very low formaldehyde emissions (E1 or higher).
High mechanical strength, good dimensional stability, easy to cut and fasten.

It is the most widely used type of OSB in Spain and Europe for dry construction structures and roofing.
