CCEWOOL® Rock Wool Board 80

CCEWOOL® Rock Wool Board 80 is a high-performance rigid stone wool insulation board designed for exterior continuous insulation systems in both residential and commercial buildings. It offers exceptional thermal, fire-resistant, and acoustic performance.

This product is fire-resistant and does not produce smoke or propagate flames, providing a critical line of defense that keeps occupants safe and reduces property damage during a fire. It helps delay the spread of fire and offers valuable extra time for evacuation and firefighting efforts, minimizing damage.

CCEWOOL® Rock Wool Board 80 integrates thermal insulation, fire safety, and soundproofing into a comprehensive solution that ensures safe, comfortable, and energy-efficient buildings.

Benefits

  • Noise Reduction and Enhanced Comfort

    Rock wool materials provide excellent sound absorption, effectively reducing noise and creating a quiet and productive environment.

  • Vapor Permeable, Reduces Moisture Risk

    The product's vapor permeability enhances the drying ability of wall systems, reducing the potential for condensation and water accumulation that could cause structural damage.

  • Superior Fire Protection for Safety

    With exceptional fire resistance, it can withstand extreme temperatures up to 2,150°F (1,177°C), creating a robust protective barrier.

  • Minimizes Thermal Bridging, Improves Energy Efficiency

    Effectively reduces thermal bridging in wood-framed buildings, significantly improving the overall thermal performance and energy efficiency of the structure.

Features of Rock Wool Board 80

  • Easy to Cut

    Can be easily cut using a bread knife, making installation and construction quick and convenient.

  • Non-Combustible

    With a melting point of up to 1,177°C (2,150°F), it provides excellent high-temperature performance, ensuring fire safety.

  • Excellent Sound Absorption

    Offers superior sound absorption, effectively reducing noise transmission and enhancing the acoustic environment of buildings.

  • Good Vapor Permeability

    The breathable design allows moisture to escape, preventing water accumulation and promoting a dry building envelope.

  • Durable and Corrosion-Resistant

    Will not rot, nor promote the growth of fungi or mildew, ensuring long-term durability.

  • Low Moisture Absorption

    The material has extremely low water absorption, maintaining its thermal performance over time.

  • Chemically Inert

    Does not corrode, ensuring no detrimental effects on surrounding materials or systems.

  • Water-Repellent

    Effectively prevents moisture penetration, making it suitable for various environmental conditions.

  • Eco-Friendly Manufacturing

    Free of CFCs and HCFCs, made from natural and recycled materials, providing a sustainable, environmentally friendly solution.
