Key Benefits

Environmentally friendly wood-based board for interior and exterior use
• Excellent dimensional stability and stiffness from three-layer cross orientation
• High load-bearing capacity with strong bending, compression and tensile properties
• Very good fastener holding, even close to panel edges
• Low swelling and surface partially resistant to wetting
• Good thermal insulation and sound damping compared with similar building materials

Applications

Used where structural strength and stable panel dimensions are required; suitable for both technical and decorative applications.

Sheathing for timber truss constructions and structural frames
• Wall and roof sheathing in diffusion-open or diffusion-closed systems
• Decorative interior cladding and paneling
• Use in moist or wet conditions where OSB/3 is specified

What to Consider When Choosing

Confirm EN 300 classification: type OSB/3 matches intended structural use
1. Check fire performance: EN 13501-1 class D-s1, d0 for the project
2. Verify formaldehyde emission class E1 (EN 120) if indoor air quality matters
3. Decide if panel’s partial resistance to wetting and suitability for moist conditions meets site demands
4. Consider whether the product’s features fit diffusion-open or diffusion-closed construction systems
