CCEWOOL® Rock Wool Board 55/65

CCEWOOL® Rock Wool Board 55/65 is a medium-density rock wool insulation product, specially designed for external and internal non-load-bearing steel firewalls, providing at least 1 hour of fire protection. CCEWOOL® Rock Wool Board 65 offers a fire rating of 1 hour, while CCEWOOL® Rock Wool Board 55 provides a 2-hour fire rating (measured from the interior side). These two products allow for more flexible building designs, enabling builders to reduce building spacing and increase usable floor area while still meeting stringent fire and thermal insulation requirements.

CCEWOOL® Rock Wool Board 55/65 offers exceptional fire protection, insulation, and durability, making it an ideal choice for meeting modern building fire protection requirements, while providing more flexible and efficient design solutions for builders.

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 Rock Wool Board 55/65

  • Lightweight Design

    The material is lightweight, easy to handle and install, making it suitable for quick construction of firewall systems.

  • Easy Installation

    Easily integrated into insulation systems and firewall designs, improving construction efficiency.

  • Zero Clearance Fire Resistance

    Provides exceptional fire resistance, effectively protecting even in close proximity to other buildings.

  • Non-Combustible

    With a melting point of 1177°C (2150°F), it provides a reliable fire barrier during a fire.

  • Dimensional Stability

    Maintains dimensional stability in high-temperature environments, ensuring long-lasting fire protection and insulation performance.

  • Wide Operating Temperature Range

    Capable of performing in a broad temperature range, meeting the demands of various building environments.

  • Energy Efficiency

    Excellent insulation properties reduce heat loss, improving building energy efficiency and saving energy costs.

  • Non-Corrosive

    Chemically inert, compatible with other building materials, and will not corrode or affect the structural performance.

  • Mold and Corrosion Resistant

    The material does not rot and will not support the growth of mold, fungi, or bacteria, ensuring a healthy building environment.
