Key advantages
• Very high mechanical strength – suitable for floors
• High load-bearing capacity
• Full resistance to moisture and water
• Does not swell or warp
• High fire resistance
• Long-term dimensional stability
• Suitable for wide framing spacing
• Resistant to pests and rot
• A professional solution for lightweight floors in dry construction
Why this product
The 18 mm thickness is designed specifically for use as flooring where high load-bearing capacity and maximum stability are required.
Suitable for projects with higher loads, or where you want to reduce support spacing in the framing.
Technical description
A fibre cement board made by VISAKA (V-Board series), manufactured in an advanced autoclave process that combines cement, cellulose fibres and minerals to create an exceptionally strong board.
At 18 mm thick, the board is suitable for use as a lightweight floor on framing, providing a stable, durable and reliable solution for high loads while remaining resistant to water, fire and changing environmental conditions.
Applications
• Lightweight floors on steel framing
• Mezzanine floors (galleries)
• Portable buildings
• Industrial buildings
• Service floors
• Base for ceramic tile / parquet / PVC flooring
• Areas with medium-to-high loads
