Upgrading your home's thermal performance offers significant advantages, including reduced energy expenditure and improved living comfort. The Unilin XT/TL-MR Thermal Liner represents an efficient solution for achieving these objectives and enhancing your property's energy efficiency.

The PIR board also delivers fire resistance through continuous adhesive ribbons, particularly around openings such as windows and doors.

What are Insulated Plasterboards?

The 82.5mm XT/TL-MR insulated plasterboards ( 70mm insulation + 12.5mm Moisture plasterboard ) are building materials that integrate plasterboard with an insulation layer, typically PIR Insulation. The insulation layer bonds to the plasterboard, creating a single multi-functional panel offering both thermal performance and a finished surface. These panels improve thermal and sound insulation, streamline installation, and accelerate project timelines. Common applications include walls, ceilings, and floors, with various sizes and thicknesses available to match specific building needs.
