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

Description

Product Overview

Standard plasterboard sheet, measuring 2400 × 1200mm with a 12.5mm tapered edge, for use in ceilings, partitions, and wall linings where board size aligns with typical stud spacing and maximises coverage.

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.

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, offering reliable strength and stability for partitions and linings while minimising flex and reducing the risk of surface cracking.
