✔ Eco-Friendly – 100% CFC-free, recyclable, and compliant with international green building certifications
✔ Moisture & Mold Resistant – Closed-cell structure prevents water absorption (<1%)
- Excellent waterproof and moisture-proof
  Closed porosity rate > 99%, water absorption rate < 1%, completely blocking rainwater penetration and solving the problem of mold and water seepage on the wall. Anti-freeze-thaw cycle: The strength does not decay in humid environments, especially suitable for rainy areas
- Efficient insulation and energy saving
  Ultra-low thermal conductivity (0.028~0.034W/(m·K)), thermal insulation performance is more than 20% higher than EPS, significantly reducing building energy consumption
  Temperature stability: -30℃~70℃ performance without attenuation, adapting to severe cold and high temperature climates.
- Fire safety upgrade
  Level B1 flame retardant (composite fire-resistant coating can reach level A2), meeting building fire protection specifications.
  Smoke-free and non-toxic: No melting droplets at high temperatures, reducing the risk of fire spread.
- High strength protection
  Compressive strength 300-700kPa, wind pressure and impact resistance, protecting the external wall structure from external damage
  Resistant to creep: Use it for a long time without deformation, and avoid cracking and falling off the insulation layer.
