MANNOK INSULATED SLAB 25MM + 12.5MM

Improve the thermal performance of your walls with Mannok Therm Insulated Plasterboard 25mm + 12.5mm. This high-performance insulated plasterboard combines a 25mm Polyisocyanurate (PIR) insulation core with a 12.5mm standard plasterboard, providing an effective dry-lining solution that enhances energy efficiency while maintaining a slim wall profile.

The fibre-free PIR insulation core delivers a low thermal conductivity of 0.022 W/mK, helping to reduce heat loss and improve indoor comfort without requiring excessive wall thickness. This makes it an ideal choice for projects where maximising internal space is important.

Suitable for both new build and refurbishment projects, Mannok Therm Insulated Plasterboard can be installed using direct bonding (dot and dab) or mechanical fixing, making it compatible with both solid masonry and timber or metal stud walls. The rigid insulation core features low-emissivity composite foil facings, further enhancing thermal performance.

Manufactured with sustainability in mind, the board has Zero Ozone Depletion Potential (ODP) and an A+ BRE Green Guide rating, offering an environmentally responsible solution for modern construction.
