Gypsum plasterboard bonded to an expanded polystyrene foam insulate for a basic level of thermal insulation.
 
9.5mm WallBoard factory-bonded to an expanded polystyrene insulant that is both CFC and HCFC-free, meaning zero ODP (Ozone Depletion Potential), and less than 5 GWP (Global Warming Potential). Designed to be used in both refurbishment and new build for walls, ceilings and reveals where a basic level of thermal insulation is required to reduce heat loss from buildings.
