Key advantages
• Exceptionally high mechanical strength
• Improved load-bearing capacity compared with the 9 mm board
• Full resistance to moisture and water
• Does not swell or warp
• High fire resistance
• Long-term dimensional stability
• Suitable for lightweight floors with higher loads
• Resistant to pests and rot
Why this product
The 12 mm thickness strikes a balance between strength, weight and cost.
Suitable for projects that require greater load-bearing capacity than 9 mm, but where you still want a lightweight, efficient floor system.
Technical product description

Load data (floors)
• Suitable for wider framing spacing than the 9 mm board
• Higher load-bearing capacity
• Suitable for applications with medium–high loads
Reducing the framing spacing significantly improves performance
Performance
• Basic sound insulation
• Can be combined with stone wool (rock wool) / acoustic membranes for a significant improvement
