About

This Thermal Liner XT/TL system delivers high-performance thermal insulation and drylining in a single operation, making it the preferred choice for new construction and renovation work. By upgrading your home's energy efficiency, you'll benefit from lower heating bills and enhanced comfort levels.

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

Improving your property's energy performance delivers substantial advantages, from reduced utility expenses to better indoor comfort. Thin-R Thermal Liner is an effective solution for achieving these improvements and enhancing your home's thermal efficiency.

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

What are Insulated Plasterboards?

The 119.5mm XT/TL insulated plasterboards (110mm insulation + 9.5mm plasterboard) combine plasterboard with an insulation layer, typically PIR, creating a single multi-functional panel. This integrated construction provides both thermal performance and a finished surface, streamlining installation. Commonly applied in walls, ceilings, and floors, these panels are available in various sizes and thicknesses to meet diverse building specifications and improve both thermal and sound insulation.
