12.5mm Knauf Wallboard Tapered Edge Plasterboard 2700mm x 1200mm

Long-length 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.Increased 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 minimising flex and reducing the risk of surface cracking.
