Meets Global Building Codes | 50% Faster Installation | 25+ Years Service Life

Core Advantages

1. Superior Thermal Insulation: Thermal conductivity of ≤0.023 W/(m·K) and a closed-cell rate ≥90% ensure minimal heat transfer, significantly reducing HVAC energy consumption.
2. Reliable Fire Safety: The self-extinguishing core provides a fire resistance rating of up to 3 hours with low smoke and toxicity, ensuring occupant safety.
3. High Strength-to-Weight Ratio: With a core density of 40 kg/m³ and compressive strength of 2.0-2.7 kg/cm², it reduces structural load and foundation costs.
4. Excellent Air & Weather Tightness: Precision interlocking joints and full-surface lamination prevent air leakage, rain penetration, and dust ingress.
5. Fast & Flexible Installation: Factory-prefabricated panels enable dry construction, cutting project time by up to 50%. Adaptable to horizontal or vertical installation.
