Product Overview
This fire-resistant plasterboard sheet measures 2400 × 1200mm and features a 12.5mm tapered edge, making it suitable for ceilings, partitions, and wall lining applications that follow standard stud spacing. The tapered edge creates a recessed joint that allows tape and jointing compound to sit neatly within the board surface, producing a smooth, continuous finish once completed. Its standard dimensions help reduce the total number of joints required, improving installation speed while delivering consistent performance in most drylining systems. With a 12.5mm thickness, the board meets typical industry expectations for strength and stability and is designed to contribute to fire-resistant construction by helping slow the spread of flames when installed as part of an approved system.
Features & Benefits
