Key Benefits

Environmentally friendly wood-based panel suitable for interior and exterior use
• Excellent dimensional stability and stiffness from cross-oriented layers
• High load-bearing capacity with strong bending, compression and tensile performance
• Very good fastener holding, even near panel edges
• Low swelling value and partial resistance to wetting
• Good thermal insulation and sound damping compared with similar building materials
• Suitable for humid conditions and usable in diffusion-open or diffusion-closed systems

Applications

Typical applications and areas of use for this OSB/3 panel.

Timber-frame structural sheathing and bracing
• Roof decking and wall sheathing
• Subflooring and floor underlayment
• Interior decorative panels and cladding
• Temporary construction elements and formwork

What to Consider When Choosing

Choose OSB/3 for load-bearing and timber-frame applications requiring moisture resistance
1. Verify formaldehyde class E1 (EN 120) for indoor air quality requirements
2. Confirm compliance with listed standards (EN 300; EN 13501-1; EN 13986) for your project
3. Consider panel surface uniformity if used for visible or decorative applications
4. Decide between diffusion-open or diffusion-closed system compatibility based on building design
