Supplier's note

  1. Technical Breakthroughs:

    • The B2 flammability rating ensures compliance with EU fire safety standards, enabling use in hospitals and schools.
    • The -50°C to +75°C operating range outperforms standard XPS boards, ideal for Arctic or tropical climates.
    • Dual EPR certifications simplify regulatory compliance for European construction projects.

  2. Version Selection Guide:

    • Base Model: Suitable for residential bathrooms and standard exterior walls where cost efficiency is prioritized.
    • Advanced Model: Recommended for gyms and commercial buildings needing enhanced thermal resistance and moisture control.
    • Pro Model: Optimal for extreme environments (e.g., coastal warehouses, Arctic warehouses) due to its 30% higher R-value and 40% reduced water vapor permeability. With the Pro’s triple-certified chemical resistance, it safely handles corrosive marine environments when paired with its UV-resistant surface coating, ensuring long-term durability.

*Comparative benchmarks: Industry-standard XPS boards typically achieve R-values between 4.0–4.5 m²·K/W.
