The 62.5mm Thermal Liner XT/TL-MR delivers comprehensive thermal insulation and drylining performance in a single step, making it an excellent choice for new builds and renovation work. This product enhances your home's energy efficiency while delivering multiple advantages, such as lower heating bills and enhanced comfort levels.
The 62.5mm Insulation Board is chemically stable and safe in use, manufactured with a blowing agent that has zero Ozone Depletion Potential (ODP) and minimal Global Warming Potential (GWP).
Upgrading your home's thermal performance offers substantial benefits, including reduced energy expenditure and improved comfort. The Unilin XT/TL-MR Thermal Liner is a practical solution for achieving greater energy efficiency and a warmer home.
The PIR board offers fire resistance benefits through continuous adhesive ribbons, particularly around vulnerable areas such as window and door openings.
The 62.5mm XT/TL-MR insulated plasterboards (50mm insulation + 12.5mm Moisture plasterboard) combine plasterboard with an integrated insulation layer, typically manufactured from PIR Insulation. The insulation layer is bonded to the plasterboard, creating a unified panel that delivers both thermal performance and a finished surface. These products are widely used in construction to enhance thermal and sound insulation, whilst streamlining installation and reducing build time. Common applications include walls, ceilings, and floors, with options available in various sizes and thicknesses to meet specific building needs.
