Fibre Cement Boards
A1 Non-Combustible Fire Resistance
Ideal for structural applications on floors, walls, or ceilings—indoors or outdoors.
These fibre reinforced cement boards are a superior replacement for plywood and plasterboard, offering A1 Non-Combustible Fire Resistance, exceptional strength, and long-term dimensional stability.
Unlike insulation-type backer boards, they are designed to perform as a structural sheathing solution, even in demanding environments.

Technical Information
Fibre Reinforced Cement Boards
A1 Non-Combustible Structural Sheathing Board
1. Product Description
Fibre Reinforced Cement Boards are high-performance, A1 non-combustible construction boards designed for structural applications in floors, walls, and ceilings, suitable for both internal and external use.
Manufactured from cement reinforced with fibres, these boards provide exceptional mechanical strength, dimensional stability, and fire performance. They are a superior alternative to plywood and plasterboard and are engineered to function as a structural sheathing solution rather than an insulation-type backer board.
2. Key Features
A1 Non-Combustible Fire Resistance (EN 13501-1)
Structural-grade performance
High impact resistance
Moisture and mould resistant
Suitable for internal and external applications
Excellent dimensional stability
Compatible with a wide range of finishes
Square edge profile for easy jointing

4. Applications
Suitable for use in:
Structural sheathing systems
Internal partitions
Suspended ceilings
External facades
Wet rooms and bathrooms
Behind stoves and fireplaces
High-impact areas
Fire protection layers
Stud Walls & Ceilings
9mm or 12mm boards recommended for increased strength, rigidity, and improved acoustic performance.
For enhanced fire and acoustic performance:
Install a 6–12mm base layer
Overlay with a staggered 12mm top layer to reinforce joints and improve performance
5. Installation Guidelines
Cutting
Score and snap (similar to plasterboard), or
Cut using hand or power saw
Use dust extraction when cutting with power tools
Fixing Methods
Installation method depends on substrate, location, and final finish. Boards can be fixed using:
Mechanical screws
Adhesives
Drylining systems
Joint taping systems
Boards may be directly fixed to solid substrates.
For project-specific installation guidance, consult the technical team.
6. Finishing Options
Boards accept a wide range of finishes including:
Paint
Ceramic tiles
Natural stone
Plaster
Render
Screed
Cladding systems
Decorative finishes
7. Performance Summary
These fibre cement boards are engineered to perform reliably in hot, cold, wet, and dry environments. Their structural strength, fire resistance, and moisture stability make them suitable for demanding applications where traditional plasterboard or plywood would be inadequate.
8. Storage & Handling (Recommended)
Store flat on a dry, level surface
Protect from prolonged exposure to weather prior to installation
Handle with care to prevent edge damage
