40mm Thermal Basic EPS Insulated Plasterboard 2400mm x 1200mm

Thermal Basic EPS Insulated Plasterboard measuring 40mm thick and 2400mm x 1200mm in size. A laminated board combining 9.5mm standard plasterboard with an expanded polystyrene (EPS) insulation backing to improve thermal efficiency on internal walls and ceilings. The composite structure reduces heat loss through solid walls, providing an immediate uplift in energy performance while maintaining minimal loss of internal room space. Manufactured using CFC- and HCFC-free expanded polystyrene, the insulation layer offers stable thermal conductivity and low moisture absorption. The plasterboard face provides a smooth, durable surface suitable for direct painting, wallpapering, or plaster skim finishing. At 40mm overall thickness, it is suited to installations where higher levels of thermal insulation are required while retaining a slim wall build-up.
