As energy efficiency and environmental sustainability become central themes in modern construction, the thermal performance of building envelopes has emerged as a critical factor in improving overall building efficiency. In this context, continuous exterior insulation systems are increasingly replacing traditional cavity-fill methods, becoming a key component in both residential and commercial building designs. CCEWOOL® has developed Basalt Wool Board 80 specifically for such applications—a high-performance insulation product engineered for use in above-grade walls, foundation perimeters, sloped roof areas, and under concrete slabs.
Focused on Effective R-Value: The Right Solution for Evolving Building Codes
Today, building regulations in regions like Europe and North America are shifting from specifying nominal R-values of materials to emphasizing the effective R-value of the entire envelope system. This calls for insulation solutions that not only offer strong thermal resistance but also eliminate thermal bridging to ensure continuous protection.
In conventional 2x4 or 2x6 wood-frame constructions, the cavity space is often already maximized. Therefore, the most effective way to enhance the thermal efficiency of the envelope is to install a continuous insulation layer on the exterior. As one of the leading rock wool manufacturers in China, CCEWOOL® offers Basalt Wool Board 80—a premium choice that meets these modern demands with its low thermal conductivity, high compressive strength, and excellent compatibility with various construction systems.
Key Advantages of Basalt Wool Board 80
Manufactured using high-purity basalt rock and advanced production processes, CCEWOOL® Basalt Wool Board 80 delivers the following core benefits:
1. Excellent Thermal Performance – Effective Thermal Bridge Mitigation
Its high-density structure provides stable thermal resistance, forming a continuous barrier on the exterior of the system to significantly reduce heat loss caused by framing members and other structural elements.
2. Non-Combustible and Fire-Resistant – Enhanced Facade Protection
With no organic content and a melting point of 1177°C, the product is classified as A1 non-combustible. In the event of fire, it acts as a thermal barrier that slows flame spread and improves safety.
3. Vapor Permeable – Promotes Healthier Building Envelopes
Unlike traditional foam insulation boards, basalt wool offers natural vapor permeability. This helps release trapped moisture, preventing mold growth and structural decay, thereby extending the life of the building envelope.
4. Environmentally Friendly – Aligned with Sustainable Building Goals
Basalt Wool Board 80 contains a high proportion of recycled content, aligning with green building standards that prioritize low environmental impact and recyclability.
Highly Compatible – Designed for Versatility Across Structural Systems
CCEWOOL® Basalt Wool Board 80 can be directly installed on the exterior of structural sheathing using special fasteners anchored into the framing. It is compatible with both wood and steel framing systems. The product is also widely used around foundations, in basement walls, behind sloped roofing assemblies, and underneath concrete slabs, offering comprehensive thermal protection throughout the building envelope.
Building Safer, More Energy-Efficient Walls with Basalt Wool
With its consistent thermal insulation, fire resistance, and moisture control properties, CCEWOOL® Basalt Wool Board 80 delivers outstanding performance in exterior wall systems. Whether used in new energy-efficient buildings or retrofit upgrades of older structures, it is a highly effective solution for improving the energy performance and resilience of building envelopes.
