12.5mm Knauf Wallboard Square Edge Plasterboard 2400mm x 1200mm

Standard plasterboard sheet, measuring 2400 × 1200mm with a 12.5mm square edge, for use in ceilings, partitions, and wall linings where board size aligns with typical stud spacing and maximises coverage.The square edge profile allows boards to butt cleanly together without a recess, making it suited to textured finishes, direct decoration, or traditional jointing and plaster skim methods.Standard dimensions reduce the number of joints required across walls and ceilings, improving installation efficiency while maintaining dependable performance in partition and lining systems.At 12.5mm thick, the board represents the industry standard, providing reliable strength and stability for partitions and linings while minimising flex and reducing the risk of surface cracking.
