Product Information

Insulated plasterboard, measuring 37.5mm in overall thickness for use on internal walls and ceilings.
Combines a rigid polyisocyanurate (PIR) insulation core with a 12.5mm tapered-edge plasterboard lining. This dual-purpose construction improves thermal performance while providing a surface that is ready for direct decoration.
The bonded plasterboard eliminates the need for a separate lining, saving time on site and ensuring a neat internal finish.

  • 2-in-1 board (insulation + plasterboard): Speeds up installation by combining thermal lining and finishing in a single sheet.
  • PIR insulation core (0.022 W/m·K): Reduces heat loss while limiting required build-up depth.
  • Tapered edge plasterboard: Allows for neat jointing, skim finishing, and a paint-ready surface.
  • Inbuilt vapour control layer: Provides moisture resistance and helps limit condensation risk.
  • Lightweight but rigid: Easy to cut, handle, and install with standard tools.
  • Environmental credentials: Zero ODP, low GWP blowing agent, and BRE Green Guide Rating A+.
  • BBA certified (16/5357): Approved for use in roofs and internal wall applications.
  • Board size 2400 x 1200mm: Standard plasterboard dimensions minimise joints and speed coverage.
  • Thickness 37.5mm (25mm + 12.5mm): Versatile choice for refurbishments and meeting minimum Building Regulations.
  • Solid masonry walls: Upgrading thermal performance with a drylined finish.
  • Roofs (pitched/flat): Used as the underneath layer of insulation between or under rafters and joists.
  • Timber frame lining: Provides thermal lining and ready-to-finish surfaces in frame constructions.
  • Internal wall and ceiling linings: Fast, efficient upgrade in both new-build and refurbishment projects.
