Mannok Therm PIR Floor Insulation 25mm is a high-performance insulation board designed to improve the thermal efficiency of solid and suspended floors in both residential and commercial buildings.
With an impressively low thermal conductivity of 0.022 W/m²K, it effectively reduces heat loss while maintaining a slim profile. Its rigid, fibre-free core is faced with a low-emissivity composite foil, enhancing performance, particularly in underfloor heating systems.
Mannok Therm PIR Floor Insulation features high compressive strength, allowing it to withstand heavy loads over time.
Environmentally conscious, it holds an A+ rating in the BRE Green Guide, has zero ozone depletion potential (ODP), and a low global warming potential (GWP) of less than 5. It meets BS EN 13165 standards and is CE marked for quality assurance.
- High Thermal Performance with a low thermal conductivity of 0.022 W/m²K
- Designed with high compressive strength, it withstands heavy loads, ensuring long-term stability in both solid and suspended floor applications
- The rigid PIR core with a low emissivity composite foil enhances the efficiency of underfloor heating systems by improving heat distribution
- Achieves an A+ rating in the BRE Green Guide, has zero ozone depletion potential (ODP), and a low global warming potential (GWP) of less than 5
