Fire Resistant Plasterboard Tapered Edge 15mm x 2700mm x 1200mm (36 Per Pallet)
Typical applications
Fire resistant plasterboard is specified in buildings subject to Building Regulations Part B (Fire Safety) requirements. Common uses include stairwells, escape routes, communal areas in flats, plant rooms, and any wall or ceiling requiring fire rating classification. The 15mm thickness provides a balance between fire performance and practical installation, suitable for both new build and refurbishment projects where upgrading fire safety is necessary.
- Multi-storey residential and commercial buildings
- Staircase enclosures and fire-rated partitions
- Ceiling systems in commercial premises
- Compartmentation walls to contain fire spread
- Areas requiring 30-minute, 60-minute or 120-minute fire ratings depending on specification
Installation and fixing
Fire resistant plasterboard must be fixed securely to timber or metal studs using appropriate fixings. The tapered edge design allows for joint taping and finishing with standard plasterboard joint compounds. Spacing of fixings is critical to maintain fire rating — follow the manufacturer's installation guidance and building control requirements. Boards should be cut cleanly with a sharp utility knife or saw, and edges should be handled carefully to avoid damage that could compromise fire performance.
- Fix at 300mm centres maximum to timber studs or 600mm centres to metal studs
- Use corrosion-resistant fixings (galvanised or stainless steel screws)
- Ensure boards are in full contact with the frame
- Tape and joint all seams with fire-rated joint compound
- Do not leave gaps or voids behind boards
Limitations and site handling
Fire resistant plasterboard is heavier than standard plasterboard due to its mineral-enriched core, so adequate labour and lifting equipment should be planned. The boards are moisture-sensitive and must be stored flat and protected from damp on site. Do not expose to prolonged moisture or use in wet areas such as bathrooms or external walls without additional protection. Fire rating is only achieved when the complete system (frame, fixings, joints and finishing) is installed correctly — partial installation or poor workmanship will compromise performance.
- Store indoors on level ground, protected from weather
- Handle carefully to avoid edge damage or core crushing
- Not suitable for wet rooms or high-moisture environments without vapour barriers
- Requires skilled finishing to achieve fire rating certification
- Check Building Control approval before installation
Finishing and maintenance
Once installed and jointed, fire resistant plasterboard can be decorated with standard paints, wallpapers and finishes. The tapered edges and jointed seams should be finished flush using plasterboard joint compound and sanding to create a smooth surface. Avoid heavy impact damage or puncturing the surface, as this may compromise the fire-resistant properties. Regular inspection is recommended in commercial buildings to ensure the integrity of the fire-rated system is maintained.
- Use fire-rated joint compound for all seams and taped joints
- Sand smooth between coats for professional finish
- Apply primer and paint suitable for plasterboard
- Inspect periodically for damage, cracks or deterioration
- Repair any damage promptly using appropriate fire-rated materials
