Description
37.5mm PIR Insulated Plasterboard (25mm PIR + 12.5mm Board)
Achieve superior thermal efficiency and complete a two-step job in a single application with our high-performance 37.5mm PIR Insulated Plasterboard. This premium, 2-in-1 thermal laminate features a 25mm rigid polyisocyanurate (PIR) insulation core factory-bonded to a 12.5mm standard gypsum plasterboard face.
Engineered for both internal wall linings and ceiling applications, it offers an exceptionally thin profile that maximizes thermal performance while retaining valuable indoor floor space.
Key Features & Benefits
-
- Space-Saving Design: At just 37.5mm overall thickness, it provides excellent insulation without severely encroaching on room dimensions—perfect for tight corridors, window reveals, and small bedrooms.
- Advanced PIR Core: Delivers ultra-low thermal conductivity (approx. 0.022 W/mK), offering up to double the heat retention of standard polystyrene (EPS) alternatives at the same thickness.
- Integrated Vapour Control: Features an internal foil backing that acts as a highly effective vapour barrier, preventing interstitial condensation and protecting your wall structure from damp.
- Fast, Dual-Action Installation: Cuts project timelines in half by allowing you to insulate and dryline internal walls, loft conversions, or rafters in one single step.
- Highly Versatile Fixing: Fully compatible with mechanical screw-fixings onto timber studwork and metal framing, or direct application to solid masonry using perimeter foam adhesive.
