About

This thermal liner delivers high-performance thermal insulation and drylining in a single operation, making it the preferred choice for new builds and renovation projects. It enhances your home's energy efficiency with benefits including lower heating costs and improved comfort levels.

The 57.5mm 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, from reduced utility bills to enhanced living comfort. The Unilin XT/TL-MR Thermal Liner is an effective solution for achieving these improvements and creating a more energy-efficient home.

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

What are Insulated Plasterboards?

The 57.5mm XT/TL-MR insulated plasterboards (45mm insulation + 12.5mm moisture plasterboard) combine plasterboard with an insulation layer, typically PIR insulation. The insulation layer bonds to the plasterboard, creating a single multi-functional panel that delivers both thermal performance and a finished surface. These panels improve thermal and sound insulation, whilst streamlining installation. Commonly used in walls, ceilings, and floors, they're available in various sizes and thicknesses to meet different building specifications.
