Vapour Plasterboard

Vapour Plasterboard: High-Performance Moisture Barrier for Walls and Ceilings

Vapour plasterboards (also known as vapour panels or vapour barrier boards) feature a high-performance gypsum core bonded with quality paper facings and a metallised polyester foil layer laminated to one side. This specialist construction creates an effective vapour control layer that prevents moisture diffusion through walls and roofs.

Leading manufacturers including British Gypsum, Knauf, and Siniat produce vapour plasterboard solutions designed for superior moisture protection in bathrooms, kitchens, and other high-humidity spaces where condensation control is essential.
