CCEWOOL® Curtain Wall Insulation Board 40/80

CCEWOOL® Curtain Wall Insulation Board is a high-performance semi-rigid stone wool insulation board designed for curtain wall systems. It offers outstanding fire protection and thermal performance. Its non-combustible properties ensure that it will not produce smoke or contribute to flame spread when exposed to fire, providing reliable safety for buildings. Additionally, this product features moisture resistance and corrosion protection, ensuring long-term thermal efficiency for wall components.

We offer two specifications to meet different curtain wall design needs:
CCEWOOL® Curtain Wall Insulation Board 40: With a minimum nominal density of 4 PCF, it is suitable for standard curtain wall insulation needs and meets relevant insulation standards.
CCEWOOL® Curtain Wall Insulation Board 80: With a minimum nominal density of 8 PCF, it provides higher density and compressive strength, making it suitable for curtain wall systems with higher performance requirements.
Choosing the appropriate product depends on the specified perimeter fire containment system requirements of the project.

CCEWOOL® Curtain Wall Insulation Board is a high-performance solution designed for modern curtain wall systems, combining fire protection, thermal insulation, moisture resistance, and durability, providing greater safety and long-lasting protection for buildings.

Benefits

  • Outstanding Fire Protection

    Will not burn, produce toxic smoke, or contribute to flame spread, providing a reliable fire barrier for buildings.

  • Excellent Acoustic Performance

    Effectively absorbs sound and reduces noise transmission, improving workplace quietness and productivity.

  • Water Resistance

    Does not absorb moisture and allows vapor to pass through, preventing the buildup of moisture that could affect the structure.

  • Long-lasting Durability

    Maintains stable performance over time, resistant to mold growth, providing long-term protection for the building.

Features of Curtain Wall Insulation Board 40/80

  • Low Moisture Absorption

    Effectively expels moisture from the exterior wall system, preventing damp buildup.

  • Superior Thermal Protection

    Provides a higher R-value, ensuring long-term stable insulation performance.

  • Non-Combustible

    With a melting point of approximately 2,150°F (1,177°C), it provides a strong protective barrier in case of fire.

  • Sound Absorption

    Excellent sound absorption performance, reducing noise transmission and enhancing indoor environmental quality.

  • Chemically Inert

    Stable material properties with no corrosive effects, ensuring no impact on surrounding structures and components.

  • Water-Resistant

    Resistant to water penetration, will not rot or promote mold, fungi, or bacteria growth, ensuring a healthy building environment.

  • Reinforced Foil Facing

    Optional reinforced foil surface enhances the product’s strength and application flexibility.
