109.5mm Unilin XT/TL Insulated Plasterboard

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

109.5mm Thin-R Thermal Liner XT/TL Insulated Plasterboard combines a Unilin 100mm PIR insulation core with composite kraft facings bonded to 9.5mm tapered edge plasterboard using a proprietary adhesive system. This composite panel delivers both thermal performance and drylining in a single installation.

Engineered for internal wall applications, the integral vapour control layer in the composite kraft facings helps manage moisture and prevent condensation buildup. The Thin-R Thermal Liner offers substantial thermal insulation alongside drylining capabilities, making it an excellent choice for new builds and refurbishment work.

About

This 109.5mm Thermal Liner XT/TL delivers comprehensive thermal insulation and drylining in a single operation, making it the preferred choice for new construction and renovation projects. It enhances your home's energy efficiency whilst reducing heating costs and creating more comfortable living spaces.

The 109.5mm Insulation Board is chemically inert and manufactured with a blowing agent featuring zero Ozone Depletion Potential (ODP) and minimal Global Warming Potential (GWP), ensuring environmental responsibility.

Upgrading your home's thermal performance delivers significant advantages, including lower energy bills and enhanced comfort levels. Thin-R Thermal Liner is an effective solution for achieving these improvements and boosting 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 109.5mm XT/TL insulated plasterboards (100mm 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 and accelerating installation. Common applications include walls, ceilings, and floors, with various sizes and thicknesses available to meet specific building needs.
