Unilin Thin-R 102.5mm XT/TL-MF Insulated Drylining Board

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

The 102.5mm XT/TL-MF Thin-R Thermal Liner (Mechanically Fixed) features a Unilin 90mm PIR insulation core bonded to 12.5mm tapered edge plasterboard with composite foil facing on both sides. This insulated composite panel delivers thermal insulation and drylining in a single application, suitable for internal walls, sloped roofs, and ceilings using mechanical fixing methods.

The dual-sided composite foil facing incorporates an integral vapour control layer to minimise condensation risk. The XT/TL Thermal Liner is engineered to deliver superior thermal performance and drylining capability simultaneously, making it an ideal choice for both new builds and refurbishment schemes.

About

The 102.5mm Thermal Liner XT/TL-MF combines thermal insulation and drylining capabilities in one operation, offering a practical solution for new construction and refurbishment projects. This product enhances your property's energy efficiency whilst delivering cost savings and improved comfort levels.

The 102.5mm Insulation Board is chemically inert and manufactured with a blowing agent featuring zero Ozone Depletion Potential (ODP) and low Global Warming Potential (GWP).

Upgrading your home's energy performance offers substantial advantages, including reduced heating bills and enhanced living comfort. The Unilin XT/TL-MF Thermal Liner represents an effective investment in achieving these objectives and improving your property's thermal efficiency.

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 102.5mm XT/TL-MF insulated plasterboards (90mm insulation + 12.5mm plasterboard) combine plasterboard with an integrated insulation layer, typically PIR-based. The insulation bonds to the plasterboard, creating a unified multi-purpose panel offering both thermal performance and finished surface in one product. These panels enhance thermal and sound insulation whilst streamlining installation timescales. Commonly specified for walls, ceilings, and floors, they are available in various dimensions and thicknesses to match specific building needs.
