82.5mm PIR Insulated Plasterboard 2400mm x 1200mm

Insulated plasterboard, measuring 82.5mm in overall thickness for use on internal walls and ceilings.It combines a rigid polyisocyanurate (PIR) insulation core with a 12.5mm tapered-edge plasterboard lining. This dual-purpose construction enhances thermal performance while providing a surface ready for direct decoration.Faced with foil, the PIR layer improves insulation and acts as a vapour control barrier, reducing heat loss and regulating moisture within the building fabric.The bonded plasterboard removes the need for a separate lining, saving time on site and delivering a clean, professional finish.At 82.5mm thick (70mm PIR plus 12.5mm plasterboard), the board delivers high levels of thermal efficiency, making it suitable for projects where improved insulation performance is required to meet regulatory or design targets.
