Unilin Thin-R XT/TL PIR thermal liner boards are designed to improve the thermal performance of internal walls while providing a smooth plasterboard finish ready for decoration. Combining rigid PIR insulation with high-quality plasterboard, they offer an effective drylining solution for both new build and refurbishment projects.

Available in a range of thicknesses and board specifications, the Thin-R XT/TL range includes options suitable for both Dot & Dab adhesive installation and mechanically fixed applications, allowing the correct solution to be selected based on the wall construction and project requirements.

Featuring a low thermal conductivity of 0.022 W/mK, these high-performance PIR insulated plasterboards deliver excellent thermal efficiency while helping to minimise the loss of valuable internal floor space. The boards are commonly used for upgrading solid walls, masonry walls and other internal wall constructions in domestic and commercial buildings.

Available Thicknesses & Applications

The Unilin Thin-R XT/TL range is available in multiple insulation thicknesses, making it suitable for a variety of thermal performance requirements. These PIR thermal liner boards are ideal for internal wall insulation projects where space-saving, ease of installation and long-term thermal performance are key considerations.
