32.5mm PIR Insulated Plasterboard 2400mm x 1200mm

Insulated plasterboard, measuring 32.5mm 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 32.5mm thick (20mm PIR plus 12.5mm plasterboard), the board provides a slim insulation solution, making it ideal for refurbishment projects where wall depth is limited but thermal performance still needs to be improved.
