12.5mm Gyproc Wallboard Duplex Tapered Edge Plasterboard 2400mm x 1200mm

Condensation is costly; not only that, but it can be incredibly stressful, threatening damage to the structural integrity of your home. Gyproc WallBoard Duplex Tapered Edge Plasterboard is specifically purposed to fight against condensation, offering plasterboard lining and vapour control in one fixing operation. 

Suitable for drylining most internal wall and ceiling linings, Gypsum Gyproc Wallboard Duplex comprises an aerated gypsum core encased in strong paper liners. The boards boast a vapour-controlled membrane (an additional metalised polyester film on the back face), firmly bonded to the aerated gypsum centre. 

The 1200mm x 2400mm x 12.5mm boards showcase a tapered edge, making them ideal for both jointing and skimming and providing a smooth, inert surface for a decorative finish in internal walls and ceilings. 

12.5mm Gyproc Wallboard Duplex Tapered Edge Plasterboard Applications

British Gypsum Gyproc Wallboard does an excellent job of drylining internal surfaces. We recommend Gyproc Duplex for walls and ceiling linings where vapour control is needed; the boards are not unsuitable for use in areas subject to continuously damp or humid conditions. The boards can be applied to timber and metal partitions with mechanical fixings and to various brick/masonry backgrounds with plasterboard adhesive.

12.5mm Gyproc Wallboard Duplex can also be installed in the following applications: 

• Ceiling linings where vapour control and plasterboard lining are required
• External walls 
• Roof spaces

Openings for switch or socket boxes should be considered before installing the boards.
