Ultra Liner 42.5mm Insulated Plasterboard

42.5mm Ultra Liner Insulated Plasterboard combines a high-performance PIR insulation layer with 12.5mm tapered edge plasterboard, offering thermal insulation and drylining in one product for walls, ceilings and pitched roofs. Ideal for new build and refurbishment schemes, this board delivers both insulation and finishing capability simultaneously.

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

The rigid polyisocyanurate (PIR) core is faced with kraft foil paper on both sides, featuring an integral vapour control layer. Installation is straightforward using drywall adhesive or mechanical fixings, making it adaptable for numerous internal wall and roof scenarios.

This insulated plasterboard effectively minimises heat loss, enhancing thermal performance and contributing to energy-efficient building design.

The composite kraft foil facings on both surfaces incorporate a built-in vapour control layer, reducing condensation risk whilst boosting overall thermal efficiency.

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 simple—use a sharp knife or fine-toothed saw for cutting. Always wear appropriate PPE when handling or fitting insulated plasterboard.
