Mannok Therm PIR Floor Insulation 100mm is a high-performance PIR insulation board designed to enhance the thermal efficiency of solid and suspended floors in residential and commercial buildings.
With a low thermal conductivity of 0.022 W/m²K, this floor insulation minimises heat loss while maintaining a slim profile. Its rigid, fibre-free core is faced with a low emissivity composite foil, optimising performance and making it particularly effective for underfloor heating systems.
Boasting high compressive strength, it withstands heavy loads, ensuring long-term durability.
Environmentally friendly, it holds an A+ rating in the BRE Green Guide, features zero ozone depletion potential (ODP), and has a low global warming potential (GWP) of less than 5. Complies with BS EN 13165 standards and is CE marked.
- 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
