Ultra Liner 37.5mm Insulated Plasterboard

37.5mm Ultra Liner Insulated Plasterboard combines a high-performance PIR insulation layer bonded to 12.5mm tapered edge plasterboard, engineered for internal walls, ceilings and pitched roofs. This integrated solution delivers both thermal insulation and drylining in a single installation, making it ideal for new build and refurbishment applications alike.

The PIR insulation core achieves a thermal conductivity of 0.022 W/mK, supporting improved U-values and enhanced energy efficiency across a variety of wall and roof constructions.

The rigid polyisocyanurate (PIR) insulation layer is faced with kraft foil paper on both sides, enabling installation via drywall adhesive or mechanical fixings. This adaptable approach suits numerous internal wall and roof scenarios.

The laminated board features composite kraft foil facings with an integral vapour control layer, which minimises condensation risk whilst enhancing the system's thermal performance.

37.5mm Ultra Liner insulated plasterboards effectively reduce heat loss, boosting thermal performance and supporting energy-conscious building practices.

Ultra Liner boards serve as a practical alternative to Sopratherm PL4000, Quinn Therm Laminate, XT/TL Thermal Liner, Gyproc Thermaline and Knauf Laminates.

Installation is straightforward—simply cut using a sharp knife or fine-toothed saw. Always wear appropriate PPE when handling or fitting insulated plasterboard.
