62.5mm Unilin Thin-R XT/TL-MF Insulated Drylining Board

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

The 62.5mm XT/TL-MF Thin-R Thermal Liner (Mechanically Fixed) features a Unilin 50mm PIR insulation core bonded to 12.5mm tapered edge plasterboard with composite foil facing. This insulated composite panel delivers both thermal performance and drylining in a single product, ideal for internal walls, sloped roofs, and ceilings where mechanical fixing is required.

The 62.5mm Insulated Plasterboard incorporates composite foil facing on both sides with an integral vapour control layer to minimise condensation risk. Engineered specifically for mechanically fixed applications, the XT/TL Thermal Liner combines high thermal insulation with drylining in one operation, making it a practical choice for new builds and renovation work.

About

The 62.5mm Thermal Liner XT/TL-MF combines thermal insulation with drylining in one step, offering an efficient solution for new construction and refurbishment projects. This product enhances your property's energy performance whilst reducing heating costs and creating a more comfortable living environment.

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 significant advantages, including lower energy bills and enhanced comfort levels. The Unilin XT/TL-MF Thermal Liner is an effective choice for achieving improved energy efficiency in your property.

The PIR board also delivers fire resistance benefits through continuous adhesive ribbons, particularly around openings such as windows and doors.

What are Insulated Plasterboards?

The 62.5mm XT/TL-MF insulated plasterboards ( 50mm insulation + 12.5mm plasterboard ) combine plasterboard with an insulation layer, typically manufactured from PIR Insulation. The insulation core is bonded to the plasterboard, creating a unified multi-functional panel that provides both thermal performance and a finished surface. These products are widely used in construction to enhance thermal and sound insulation whilst streamlining installation. They suit walls, ceilings, and floors in various sizes and thicknesses to match specific building needs.
