Product Overview
Insulated plasterboard combining PIR insulation with a plasterboard finish.
PIR insulated plasterboard delivers reliable thermal performance while providing a ready-to-decorate lining for internal walls and ceilings.
At 32.5mm overall thickness (20mm PIR bonded to 12.5mm plasterboard), this is the slimmest option, best suited to improving insulation in tight spaces.
Features & Benefits
- 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+.
- Board size 2400 x 1200mm: Standard plasterboard dimensions minimise joints and speed coverage.
- Thickness 32.5mm (20mm + 12.5mm): Slim option for space-constrained applications.
Applications
- 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.
Installation Guidance
- Fixing options: Suitable for dot-and-dab adhesive bonding or mechanical fixings.
- Joint treatment: Use joint tape and compound at tapered edges for a smooth finish.
- Cutting and handling: Score and snap plasterboard; use fine-toothed saw for PIR core; handle with care to avoid edge damage.
- Moisture precautions: Store flat, dry, and covered; protect from prolonged sunlight or damp before installation.
Compliance & Performance
- Thermal conductivity: 0.022 W/m·K (PIR insulation).
- Reaction to fire: Euroclass B-s1, d0 (BS EN 13501-1).
- Compressive strength: ≥120 kPa (BS EN 826).
- Environmental performance: Zero ODP, low GWP, BRE Green Guide Rating A+.
