74.5mm Unilin Thin-R XT/TL-MF Insulated Drylining Board

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

The 74.5mm XT/TL-MF Thin-R Thermal Liner (Mechanically Fixed) features a Unilin 65mm PIR insulation layer combined with composite foil facing, bonded to 9.5mm tapered edge plasterboard. This composite panel delivers both insulation and drylining for internal walls, sloped roofs, and ceilings, though it is designed exclusively for mechanical fixing applications.

The 74.5mm Insulated Plasterboard incorporates composite foil facing on both sides with an integrated vapour control layer, helping to minimise condensation risk. This mechanically fixed thermal liner delivers substantial thermal performance alongside drylining in a single installation step, making it the ideal choice for new builds and renovation work.

About

This 74.5mm Thermal Liner XT/TL-MF combines thermal insulation with drylining in a single step, offering an efficient solution for new construction and refurbishment projects. It enhances your home's energy performance whilst delivering benefits such as lower heating costs and improved comfort levels.

The 74.5mm 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 brings substantial advantages, including reduced energy bills and enhanced living standards. The Unilin XT/TL-MF Thermal Liner represents a practical solution for achieving these improvements and boosting your property's energy efficiency.

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 74.5mm XT/TL-MF insulated plasterboards ( 65mm insulation + 9.5mm plasterboard ) combine plasterboard with an integrated insulation layer, typically PIR-based. The insulation bonds to the plasterboard, creating a unified panel that provides both thermal performance and a finished surface. These panels are widely used in construction to enhance thermal and sound insulation, whilst streamlining installation. They suit walls, ceilings, and floors, available in various sizes and thicknesses to match specific building needs.
