The 32.5mm Thermal Liner XT/TL delivers thermal insulation and drylining simultaneously, making it the preferred choice for new construction and refurbishment work. This solution enhances your home's energy performance, reducing heating costs and creating a more comfortable living environment.
The 32.5mm Insulation Board is chemically stable and manufactured with a blowing agent featuring zero Ozone Depletion Potential (ODP) and minimal Global Warming Potential (GWP), ensuring environmental responsibility.
Upgrading your home's energy efficiency delivers tangible advantages, including lower utility bills and enhanced comfort. Thin-R Thermal Liner is an effective solution for achieving superior energy performance in your property.
The PIR board offers fire resistance benefits through continuous adhesive ribbons, particularly around vulnerable areas such as window and door openings.
The 32.5mm XT/TL insulated plasterboards (combining 20mm insulation with 12.5mm plasterboard) are composite building materials that integrate insulation with plasterboard, typically using PIR technology. The insulation layer bonds to the plasterboard, creating a single multi-purpose panel offering 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 various sizes and thicknesses available to meet specific building needs.
