72.5mm Celotex PL4060 Insulated Plasterboard 2400mm x 1200mm

Insulated plasterboard, measuring 72.5mm in overall thickness for use on internal walls and ceilings.Manufactured as part of the PL4000 range, it combines a rigid polyisocyanurate (PIR) insulation core with a 12.5mm tapered-edge plasterboard lining. This dual-purpose construction improves thermal performance while providing a surface that is ready for direct decoration.The PIR layer is faced with foil to enhance insulation and act as a vapour control barrier, reducing heat loss and helping to manage moisture within the building fabric. The bonded plasterboard eliminates the need for a separate lining, saving time on site and ensuring a neat internal finish.At 72.5mm thick (60mm PIR plus 12.5mm plasterboard), the board provides the highest insulation level in the PL4000 range, making it ideal for projects where maximising thermal efficiency is the priority.
