122.5mm Unilin XT/TL Insulated Plasterboard

Unilin Insulation | The new name for Xtratherm Insulation in the UK & Ireland.

122.5mm Thin-R Thermal Liner XT/TL Insulated Plasterboard (Dot & Dab) combines a Unilin 110mm PIR insulation core with two composite kraft facings. These facings bond to 12.5mm tapered edge plasterboard using a proprietary adhesive system.

Engineered for internal wall applications, this product features composite kraft facing on both sides with an integral vapour control layer to minimise condensation risk. The Thin-R Thermal Liner delivers superior thermal performance alongside drylining in a single installation, making it ideal for new builds and renovation work.

Upgrading your home's energy performance delivers substantial advantages, including lower heating costs and enhanced living comfort. Thin-R Thermal Liner represents an effective solution for achieving these improvements and boosting your property's thermal efficiency.

The PIR board offers fire resistance benefits through continuous adhesive ribbons, particularly around openings such as windows and doors.

What are Insulated Plasterboards?

The 122.5mm XT/TL insulated plasterboards ( 110mm insulation + 12.5mm plasterboard ) combine plasterboard with an integrated insulation layer, typically manufactured from PIR Insulation. The insulation layer bonds to the plasterboard, creating a unified, multi-purpose panel that offers both thermal performance and a finished surface. These panels are widely used in construction to enhance thermal and sound insulation, whilst streamlining and accelerating installation. Applications include walls, ceilings, and floors, with various sizes and thicknesses available to meet specific building needs.
