12.5mm Knauf Vapour Panel Tapered Edge Plasterboard 2400mm x 1200mm

Foil-backed vapour-control plasterboard sheet, measuring 2400 × 1200mm with a 12.5mm tapered edge, for use in partitions, linings, and ceilings where condensation risk needs to be managed. Features an aerated gypsum core finished with a metallised foil backing, creating a built-in vapour barrier that reduces moisture transfer through walls and ceilings. This helps control condensation, minimises the risk of mould growth, and supports thermal efficiency in kitchens, bathrooms, and utility areas. 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 provides the industry-standard depth for drylining, combining structural stability with integrated vapour control to manage condensation risks.
