Phenolic Foam Board 40 kg/m³ Lightweight B1 Roof Insulation
Lightweight phenolic foam board at 40 kg/m³ with B1 fire rating and λ≤0.021 W/m·K. Optimised for flat roof insulation, metal deck roofing systems, and industrial building envelopes where minimising dead load is critical.
// Key Features
- Ultra-low density 40 kg/m³ reduces structural dead load on long-span roof systems
- Lowest thermal conductivity ≤0.021 W/m·K across the phenolic foam board range
- B1 fire-rated compliance for roof assemblies under national building codes
- No fiber content — no skin irritation during on-site cutting and handling
