Sopratherm Thermal Laminate Insulation Board PL4065 2400mm x 1200mm x 65mm 12.5mm PIR (77.5mm overall)

Upgrade solid wall thermal performance with the Sopratherm PL4065 thermal laminate insulation board, supplied in a 400 x 1200mm size with a 77.5mm overall thickness (65mm PIR bonded to 12.5mm plasterboard). Engineered from rigid polyisocyanurate (PIR) foam bonded to tapered edge plasterboard, this high-performance board installs both insulation and drylining in one operation.

Delivering a low thermal conductivity of 0.022 W/m.K, the board provides excellent thermal resistance for solid wall and roof applications while featuring zero ozone depletion and a low global warming impact. The plasterboard facing is defined as Class O in accordance with building regulations.

BBA and OFGEM approved, this board is suitable for pitched roof, flat roof, and wall projects. It accommodates both direct bonding "dot and dab" and mechanically fixed installation techniques.

• 77.5mm overall thickness – combines 65mm PIR foam with 12.5mm tapered edge plasterboard
• 400 x 1200mm sheet size – specialized narrow dimensions ideal for reveals and tight wall spaces
• 0.022 W/m.K thermal conductivity – reduces heat loss significantly in solid wall constructions
• Single-operation installation – applies insulation and ready-to-finish plasterboard together
• Dual-fixing compatibility – install using "dot and dab" adhesive or mechanical fixings
• BBA and OFGEM approved – verified compliance for roof and wall thermal upgrades
• Available in various sizes – including 37.5mm, 52.5mm, 62.5mm, and 72.5mm overall thicknesses
