Unilin XT/TL 72.5mm Insulated Plasterboard

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

The 72.5mm Thin-R Thermal Liner XT/TL Insulated Plasterboard (Dot & Dab) combines a 60mm PIR insulation core with two composite kraft facings, bonded to 12.5mm tapered edge plasterboard using a proprietary adhesive system.

Engineered for internal wall applications, this composite panel features an integral vapour control layer on both sides to minimise condensation risk. The Thin-R Thermal Liner delivers comprehensive thermal insulation and drylining performance in a single installation, making it an excellent choice for new builds and refurbishment work.

About

This Thermal Liner XT/TL system delivers comprehensive thermal insulation alongside drylining in a single operation, making it the preferred choice for new construction and refurbishment schemes. It enhances your home's energy performance with multiple advantages, including lower heating bills and improved comfort levels.

The Insulation Board is chemically stable and manufactured using a blowing agent with zero Ozone Depletion Potential (ODP) and minimal Global Warming Potential (GWP), ensuring safe handling and environmental responsibility.

Upgrading your home's energy efficiency offers substantial benefits, from reduced utility expenses to enhanced living comfort. Thin-R Thermal Liner represents an effective solution for achieving these improvements and boosting overall energy performance.

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

What are Insulated Plasterboards?

The 72.5mm XT/TL insulated plasterboards (60mm insulation + 12.5mm plasterboard) combine plasterboard with an integrated insulation layer, typically manufactured from PIR. This bonded construction creates a single, versatile panel offering 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 timescales. Common applications include walls, ceilings, and floors, with options available in multiple sizes and thicknesses to meet specific building needs.
