Knauf Drywall Fire Panel Tapered Edge Plasterboard - 2700mm x 1200mm
Long-length fire-resistant plasterboard sheet, measuring 2700 × 1200mm with a 12.5mm tapered edge,...Long-length fire-resistant plasterboard sheet, measuring 2700 × 1200mm with a 12.5mm tapered edge, for use in ceilings, partitions, and wall linings where reducing horizontal joints improves finish quality. The tapered edge profile creates a shallow recess at board joints, designed to accommodate tape and jointing compound. Once filled and finished, the surface becomes seamless and ready for direct decoration. Longer board length reduces or eliminates the need for horizontal joints in standard-height rooms, improving installation efficiency and delivering a cleaner, more uniform finish. At 12.5mm thick, the board represents the industry standard, offering reliable strength and stability for partitions and linings while helping to slow the spread of flames and support fire-resistant construction.

FAQs
What is the main advantage of the long length (2700mm)?
The 2700mm length significantly reduces or eliminates horizontal joints in standard-height rooms, leading to a faster installation and a cleaner, more uniform finish with fewer visible seams.
What does 'tapered edge' mean for installation?
The tapered edge creates a shallow recess along the board's length, which is designed to hold jointing tape and compound, allowing for a smooth, seamless transition between boards once finished.
Is this board suitable for bathrooms or wet areas?
While the board itself offers fire resistance, it is not inherently waterproof. For wet areas like bathrooms, it must be used with an appropriate tanking or waterproofing membrane system.
How do I achieve a seamless finish?
Proper jointing is key. Use jointing tape on the tapered edges and apply multiple thin coats of jointing compound, sanding smooth between applications, to create a flat, continuous surface.
What is the fire resistance rating of this board?
The board is designed to help slow the spread of flames and support fire-resistant construction. Specific fire ratings depend on the complete system construction (framing, insulation, etc.). Consult technical documentation for detailed fire performance data.
Can I paint directly onto the board after jointing?
Yes, once the jointing compound is dry and has been sanded smooth, the surface is ready for priming and direct decoration (painting, wallpapering, etc.).
Troubleshooting
Board is difficult to cut cleanly.
Ensure you are using a sharp scoring knife or saw blade. For knife cuts, score deeply multiple times along a straight edge before snapping. For saw cuts, a fine-toothed blade is recommended.
Joints are not becoming seamless.
Verify that the tapered edges are fully covered with jointing tape and sufficient compound. Apply multiple thin coats of compound rather than one thick coat. Ensure the board is properly fixed to minimize movement.
Screws are tearing the board paper.
Adjust your screw gun depth setting to ensure screws are driven just below the surface without breaking the paper. Ensure the framing is rigid and doesn't flex excessively when screwing.
Board surface is uneven after finishing.
Ensure adequate lighting to spot imperfections during sanding. Apply thin, even coats of jointing compound. If significant undulation exists, it may require re-application of compound or checking the flatness of the underlying framing.
Pros and Cons
Pros
Significantly reduces the number of horizontal joints, improving installation speed.
Contributes to a more aesthetically pleasing, seamless finish.
Offers essential fire resistance properties for safety and compliance.
Industry-standard 12.5mm thickness ensures durability and stability.
The tapered edge is optimized for easy and effective joint taping and filling.
Cons
Longer length requires more space for storage and maneuvering during installation.
May be heavier and more difficult to handle for single installers compared to shorter boards.
Requires specific jointing techniques to achieve the seamless finish.
Not suitable for applications requiring extreme impact resistance without additional protection.
Setup, Compatibility & Care
Setup & Installation:
Handling: Due to its size, ensure adequate space and assistance for moving and positioning the boards.
Cutting: Use a fine-toothed saw or utility knife for accurate cuts. Score deeply and snap for straight cuts.
Fixing: Fix boards to suitable framing (timber or metal studs) using drywall screws. Ensure screws are spaced correctly and driven just below the surface without tearing the paper.
Jointing: Apply jointing tape over the tapered edges and then cover with jointing compound. Allow each coat to dry fully before applying the next and sanding smooth.
Compatibility:
Compatible with standard drywall framing systems (timber and metal studs).
Suitable for use with common drywall screws, jointing tapes, and compounds.
Designed to work with standard insulation materials within wall and ceiling cavities.
Care:
Keep boards dry and protected from moisture during storage and installation.
Once installed and decorated, the surface can be cleaned with a slightly damp cloth. Avoid abrasive cleaners.
