Flame-Retardant EPS Board 20 kg/m³ — B1 Fire Class
B1-rated flame-retardant 20 kg/m³ EPS board per GB 8624, self-extinguishing with LOI ≥28%. Thermal conductivity ≤0.038 W/(m·K). Mandated for high-rise building facades, public facility insulation, and fire-code-compliant ETICS cladding systems.
// Key Features
- Class B1 flame retardancy per GB 8624 — self-extinguishing within 3 seconds of ignition source removal
- Limiting oxygen index (LOI) ≥28% providing enhanced fire resistance over standard B2 EPS
- Full insulation performance retained: thermal conductivity ≤0.038 W/(m·K) unchanged by FR additive
- Mandatory compliance for high-rise facade and public building insulation under Chinese fire codes
