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

The 27.5mm XT/TL-MR Thin-R Thermal Liner (Moisture Resistant) combines a Unilin 15mm PIR insulation layer with a composite foil facing, bonded to 12.5mm tapered edge moisture resistant plasterboard. This composite panel works as an insulated solution for internal walls, sloped roofs, and ceilings. Installation options include both Dot&Dab and Mechanically Fixed methods.

The 27.5mm Insulated Plasterboard features a PIR rigid insulation foam core bonded to 12.5mm green moisture resistant plasterboard. This design makes it ideal for internal building areas with high humidity conditions, such as kitchens and bathrooms, and accepts plaster finishes or direct decoration.

What are Insulated Plasterboards?

The 27.5mm XT/TL-MR insulated plasterboards ( 15mm insulation + 12.5mm Moisture 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 delivers both thermal performance and a finished surface. These products are widely used in construction to enhance thermal and sound insulation, whilst streamlining the installation process. Common applications include walls, ceilings, and floors, with options available in various dimensions and thicknesses to meet specific building needs.
