Supplier's note

  1. Breakthroughs:

    • R30 Pro Model: Triple the thermal efficiency of traditional glass wool (R11), ideal for extreme climates.
    • Class A1 Fire Rating: Exceeds industry standards, preventing combustion even at 750°C.
    • Enhanced Sound Dampening: STC 35 in Pro models reduces noise pollution in hospitals and offices.

  2. Optimal Selection:

    • Base Model: Suitable for workshops requiring basic thermal barriers (e.g., storage units).
    • Advanced Model: Balances cost and performance for residential/commercial buildings needing R19–R21 insulation.
    • Pro Model: Mandatory for high-stakes environments (e.g., data centers) demanding R30+ resistance and fire safety.

*Pro Model’s R30 rating outperforms industry benchmarks by 60%, enabling energy savings of up to 40% in HVAC systems.
