SOPRATHERM PL4060 72.5mm Insulated Plasterboard

72.5mm SOPRATHERM PL4000 PIR Insulated Plasterboard (previously Celotex PL4000) combines a 60mm rigid polyisocyanurate (PIR) insulation core with a 12.5mm tapered edge plasterboard. Engineered for internal wall insulation and pitched roof applications, this thermal laminate delivers a thermal conductivity of 0.022 W/mK and provides both insulation and a finished internal surface ready for decoration.

Ideal for dry lining walls, ceilings and pitched roofs, this composite board enhances thermal efficiency in residential and commercial properties whilst minimising heat loss. Installing this single product is faster than fitting insulation and plasterboard as separate layers.

Available in thicknesses from 37.5mm to 77.5mm, the 72.5mm SOPRATHERM PL4060 suits various insulation needs. BBA certification confirms its suitability for internal wall dry lining and pitched roof ceiling insulation, meeting UK building standards.
