87.5mm Unilin Thin-R XT/TL-MF Insulated Drylining Board

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

This 87.5mm XT/TL-MF Thin-R Thermal Liner (Mechanically Fixed) combines a 75mm PIR insulation core with a composite foil facing bonded to 12.5mm tapered edge plasterboard. It delivers thermal insulation and drylining in a single product, ideal for internal walls, sloped roofs, and ceilings where mechanical fixing is required.

The 87.5mm Insulated Plasterboard features composite foil facing on both sides with an integral vapour control layer built in, helping to minimise condensation risk. Specifically engineered for mechanically fixed applications, this Thermal Liner delivers superior thermal performance and drylining capability in a single operation, making it the ideal choice for new builds and renovation work.

About

This 87.5mm Thermal Liner XT/TL-MF combines thermal insulation with drylining in a single operation, offering an efficient solution for new construction and refurbishment projects. It enhances your home's energy performance while delivering reduced energy bills and improved comfort levels.

The 87.5mm Insulation Board is chemically stable and safe, manufactured using a blowing agent with zero Ozone Depletion Potential (ODP) and minimal Global Warming Potential (GWP).

Upgrading your home's thermal efficiency offers substantial advantages, including lower heating costs and enhanced living comfort. The Unilin XT/TL-MF Thermal Liner represents an effective investment in energy efficiency and improved home 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 87.5mm XT/TL-MF insulated plasterboards ( 75mm insulation + 12.5mm plasterboard ) are building materials that merge plasterboard with an insulation layer, typically PIR-based. The insulation is bonded to the plasterboard, creating a unified multi-purpose panel offering both thermal performance and a finished surface. These products are widely used in construction to enhance thermal and sound insulation, whilst streamlining installation. They work well in walls, ceilings, and floors, with various sizes and thicknesses available to match specific building needs.
