77.5mm Ultra Liner Insulated Plasterboard combines a high-performance PIR insulation layer with 12.5mm tapered edge plasterboard, engineered for 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.
The PIR insulation core achieves a thermal conductivity of 0.022 W/mK, supporting improved U-values and enhanced energy efficiency across various wall and roof constructions.
The rigid polyisocyanurate (PIR) core features kraft foil paper facings on both sides, enabling installation via drywall adhesive or mechanical fixings. This adaptability suits numerous internal wall and roof scenarios.
The laminated board incorporates composite kraft foil facings with an integral vapour control layer, which minimises condensation risk whilst boosting thermal system performance.
77.5mm Ultra Liner insulated plasterboards effectively minimise heat loss, enhancing thermal performance and supporting energy-efficient building standards.
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 using a sharp knife or fine-toothed saw. Always wear appropriate PPE when handling or fitting insulated plasterboard.
