OSB3
Load-bearing oriented strand board (OSB/3) for structural use in humid conditions — MDI glued, moisture resistant, EN 300 classification and supporting documentation must be confirmed for the specific order.

Product Overview
OSB3 (Oriented Strand Board, Type 3) is a load-bearing structural panel designed for use in humid conditions. Manufactured with moisture-resistant MDI glue and cross-oriented strand layers for balanced strength in both directions. Conforms to EN 300 OSB/3 classification. Suitable for roofing, wall sheathing, flooring, packaging and temporary structures.
Key Features
Load-Bearing (OSB/3)
EN 300 classified for structural load-bearing applications in humid service conditions.
MDI Glue
Moisture-resistant MDI (diphenylmethane diisocyanate) glue for reliable bonding in humid environments.
Cross-Oriented Strands
Surface strands aligned parallel to panel length for bending strength; core strands cross-oriented for stability.
Consistent Panel Quality
Uniform thickness, smooth surface and clean edges for efficient installation and handling.
