The Celotex 52.5mm Insulated Plasterboard (2400mm x 1200mm - PL4040) offers a simple way to insulate and dry line in one step. It features a 40mm layer of rigid polyisocyanurate (PIR) insulation bonded to 12.5mm tapered edge plasterboard, creating an efficient 2-in-1 system. With a thermal conductivity of 0.022 W/mK and an R value of 1.85 m2.K/W, this board provides improved thermal resistance compared to thinner options, making it well-suited for projects that require higher energy performance. Easy to cut, lightweight to handle and quick to fit, it is suitable for both internal wall lining and pitched roof applications, helping to save time on installation.
