24.5mm Unilin XT/TL Insulated Plasterboard

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

24.5mm Thin-R Thermal Liner XT/TL Insulated Plasterboard (Dot & Dab) is a composite insulated panel featuring a Unilin 15mm PIR insulation core with two composite kraft facings. These facings bond to 9.5mm tapered edge plasterboard using a proprietary adhesive system.

Engineered for internal wall applications, this product combines kraft facings with an integral vapour control layer to reduce condensation risk. The Thin-R Thermal Liner delivers substantial thermal performance alongside drylining in a single application, making it ideal for new builds and renovation work.

About

The 24.5mm Thermal Liner XT/TL combines thermal insulation with drylining in a single operation, offering an excellent choice for new construction and refurbishment schemes. This solution enhances your home's energy performance whilst delivering reduced heating expenses and enhanced comfort levels.

This 24.5mm Insulation Board is chemically inert and manufactured using a blowing agent with zero Ozone Depletion Potential (ODP) and minimal Global Warming Potential (GWP).

Upgrading your home's thermal efficiency offers significant advantages, including lower energy bills and improved indoor comfort. Thin-R Thermal Liner represents an effective solution for achieving these improvements and enhancing your property's overall energy performance.

The PIR board delivers fire resistance through continuous adhesive ribbons, particularly around vulnerable areas such as window and door openings.

What are Insulated Plasterboards?

The 24.5mm XT/TL insulated plasterboards (15mm insulation + 9.5mm plasterboard) combine plasterboard with an insulation layer, typically manufactured from PIR. The insulation bonds to the plasterboard, creating a unified, multi-purpose panel delivering both thermal performance and a finished surface. These materials are widely used in construction to enhance thermal and sound insulation, whilst streamlining installation. Common applications include walls, ceilings, and floors, with options available in various sizes and thicknesses to meet specific building requirements.
