59.5mm Unilin XT/TL Insulated Plasterboard

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

The 59.5mm Thin-R Thermal Liner XT/TL Insulated Plasterboard combines a 50mm PIR insulation core with 9.5mm tapered edge plasterboard, bonded together using a proprietary adhesive system. Composite kraft facings on both sides include an integral vapour control layer to minimise condensation risk. This composite panel delivers thermal insulation and drylining in a single installation, making it ideal for internal wall applications in new builds and renovation projects.

About

This Thermal Liner XT/TL system delivers high-performance thermal insulation alongside drylining in a single operation, offering an efficient solution for new construction and refurbishment work. By enhancing your home's energy efficiency, you'll benefit from lower heating costs and improved comfort levels.

The Insulation Board is chemically inert and manufactured with a blowing agent featuring zero Ozone Depletion Potential (ODP) and low Global Warming Potential (GWP), making it environmentally responsible.

Upgrading your home's energy performance offers significant advantages, from reduced utility bills to enhanced living comfort. Thin-R Thermal Liner is an excellent choice for achieving these improvements and creating a more energy-efficient property.

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

What are Insulated Plasterboards?

Insulated plasterboards like the 59.5mm XT/TL (comprising 50mm insulation plus 9.5mm plasterboard) combine plasterboard with an insulation layer, typically made from PIR Insulation. The bonded insulation layer creates a single, multi-functional panel offering both thermal performance and a finished surface. These panels are widely used in construction to enhance thermal and sound insulation, whilst streamlining installation. Commonly applied to walls, ceilings, and floors, they're available in various sizes and thicknesses to meet different building specifications.
