Fixing and buying guide

Who this product is for

This board suits builders, contractors and serious DIY installers undertaking internal drylining work. It is the right choice for standard partitions, wall linings and ceiling installations where you do not require specialist thermal, acoustic or fire-rated performance beyond baseline levels. It works well in domestic properties, small commercial spaces and renovation projects where conventional construction performance is adequate.

Compatibility and applications

The square-edged profile is compatible with gypsum plaster skimming and textured coating systems. It is suitable for fixing to timber and metal stud framing using standard plasterboard fixings. The 12.5mm thickness is the industry standard for most partition and lining work and provides adequate strength for typical wall and ceiling spans when properly supported. Do not use this board in areas requiring enhanced fire rating, acoustic isolation or thermal insulation beyond standard performance.

• Square-edged format for plaster skim and textured finishes
• Compatible with timber and metal stud framing systems
• Standard thermal conductivity of 0.19 W/mK
• Meets normal fire and structural performance requirements

Sheet size and coverage

Each sheet is 1800mm long by 900mm wide, giving a coverage area of 1.62 square metres per board. This size is standard for efficient installation and minimises waste on most partition and ceiling layouts. Plan your layout to stagger joints and reduce the number of cut edges where possible. Calculate your total area in square metres and divide by 1.62 to determine the number of sheets required, adding 5 to 10 percent for waste and cuts.

Pre-installation checks

Before fixing, inspect each sheet for damage to edges and faces. Store boards flat and dry on a level surface in the room where they will be installed for at least 48 hours to allow acclimatisation. Check that your framing is plumb, level and properly spaced to support the board at centres not exceeding 600mm for walls and 400mm for ceilings. Ensure fixings (nails or screws) are appropriate for your frame type and are driven flush without crushing the board surface. Allow adequate ventilation during and after installation to prevent moisture trapping.

• Inspect for damage before installation
• Acclimatise boards in situ for 48 hours minimum
• Verify frame spacing meets board support requirements
• Use correct fixings for timber or metal studs
• Maintain ventilation to prevent moisture issues
