About

This Thermal Liner XT/TL panel delivers high-performance thermal insulation combined with drylining capabilities in a single operation, making it the preferred choice for new construction and refurbishment work. It enhances your home's energy efficiency whilst reducing heating costs and creating more comfortable living spaces.

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

Upgrading your home's energy performance delivers substantial advantages, including lower utility bills and enhanced comfort levels. Thin-R Thermal Liner represents an effective solution for achieving improved energy efficiency throughout your property.

The PIR board offers fire resistance benefits through continuous adhesive ribbons, particularly around vulnerable areas such as window and door openings.

What are Insulated Plasterboards?

The 52.5mm XT/TL insulated plasterboards (40mm insulation + 12.5mm plasterboard) combine plasterboard with an integrated insulation layer, typically PIR-based. The insulation bonds directly to the plasterboard, creating a single multi-purpose panel that delivers both thermal performance and a finished surface. These panels are widely used in construction to enhance thermal and sound insulation, whilst streamlining installation timescales. Common applications include walls, ceilings, and floors, with options available in various sizes and thicknesses to meet specific building needs.
