Unilin Insulation | The new name for Xtratherm Insulation in the UK & Ireland.
62.5mm Thin-R Thermal Liner XT/TL Insulated Plasterboard (Dot & Dab) combines a Unilin 50mm PIR insulation core with two composite kraft facings. The facings bond to 12.5mm tapered edge plasterboard using a proprietary adhesive system.
Engineered for internal wall installation, this composite panel features an integral vapour control layer on both sides to minimise condensation risk. The Thin-R Thermal Liner delivers substantial thermal performance alongside drylining in a single step, making it an excellent choice for new builds and renovation work.

This 62.5mm Thermal Liner XT/TL delivers comprehensive thermal insulation and drylining simultaneously, offering an ideal solution for new construction and refurbishment schemes. It enhances your home's energy performance whilst reducing heating expenses and creating more comfortable living spaces.
The 62.5mm Insulation Board is chemically stable and manufactured with a blowing agent featuring zero Ozone Depletion Potential (ODP) and minimal Global Warming Potential (GWP).
Upgrading your home's thermal efficiency delivers substantial advantages, including lower utility bills and enhanced comfort levels. Thin-R Thermal Liner represents an effective approach to achieving superior energy performance in your property.
The PIR board offers fire resistance benefits through continuous adhesive ribbons, particularly around vulnerable areas such as window and door openings.
The 62.5mm XT/TL insulated plasterboards (50mm insulation + 12.5mm plasterboard) are composite building panels that integrate plasterboard with an insulation layer, typically PIR-based. The insulation layer adheres to the plasterboard, creating a unified panel delivering both thermal performance and a finished surface. These panels are widely used in construction to enhance thermal and sound insulation, whilst streamlining installation. Common applications include walls, ceilings, and floors, available in various dimensions and thicknesses to meet specific building needs.
