Unilin Thin-R XT/TL-MF 112.5mm Insulated Drylining Board

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

The 112.5mm XT/TL-MF Thin-R Thermal Liner (Mechanically Fixed) features a Unilin 100mm PIR insulation core bonded to 12.5mm tapered edge plasterboard with composite foil facing. This composite panel delivers both insulation and drylining for internal walls, sloped roofs, and ceilings, though it is designed exclusively for mechanically fixed applications.

The 112.5mm Insulated Plasterboard incorporates a composite foil facing on both sides with an integral vapour control layer to minimise condensation risk. This mechanically fixed thermal liner combines high-performance thermal insulation with drylining in a single operation, making it the ideal choice for new builds and renovation work.

About

The 112.5mm Thermal Liner XT/TL-MF combines thermal insulation and drylining in a single operation, delivering an excellent solution for newbuild and refurbishment schemes. It enhances your home's energy performance while delivering multiple advantages, such as lower heating bills and enhanced comfort levels.

The 112.5mm Insulation Board is chemically stable and safe to handle, 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 benefits, including reduced energy expenditure and better living comfort. The Unilin XT/TL-MF Thermal Liner represents an effective way to achieve these objectives and enhance your property's energy performance.

The PIR board also delivers fire resistance through continuous adhesive ribbons, particularly around vulnerable areas such as window and door openings.

What are Insulated Plasterboards?

The 112.5mm XT/TL-MF insulated plasterboards ( 100mm insulation + 12.5mm plasterboard ) combine plasterboard with an insulation layer, typically PIR Insulation. The insulation is bonded to the plasterboard to form a single, multi-purpose panel that offers both thermal performance and a finished surface. These boards are widely used in construction to enhance thermal and sound insulation, whilst streamlining and accelerating installation. They feature across walls, ceilings, and floors, and are available in multiple sizes and thicknesses to meet varying building specifications.
