102.5mm PIR Insulated Plasterboard 2400mm x 1200mm

Insulated plasterboard, measuring 102.5mm 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 102.5mm thick (90mm PIR plus 12.5mm plasterboard), this board is designed for situations where high insulation values are needed on internal walls. It is typically used in new-build housing and extensions where wall thickness can be planned in from the outset, allowing designers to achieve stringent U-values without layering multiple products.
