In modern architecture, the roof is one of the most active areas for heat exchange in the building envelope. Whether preventing heat loss in cold climates or blocking heat penetration in hot environments, the thermal performance of the roof directly impacts a building’s energy efficiency and indoor comfort. High-performance Stone Wool Board is a key material for achieving these goals. CCEWOOL® Stone Wool Board HD is a high-density insulation board made from natural stone wool, specifically designed for low-slope roofs. It delivers outstanding thermal insulation, fire resistance, and acoustic performance, making it ideal for various roof systems in both residential and commercial buildings—including steel structure roofs, concrete roofs, and attic spaces.

Why Choose Stone Wool Board for Roof Insulation?

1. Reduces Heat Transfer, Enhances Year-Round Energy Efficiency

During winter, rising hot air escapes easily through poorly insulated roofs, with up to 25% of indoor heat lost this way. In summer, solar-heated roofs transfer heat inward, increasing cooling loads.
Stone wool insulation provides excellent thermal resistance, reducing heat flow through the roof and helping to maintain stable indoor temperatures.
Studies show that effective roof insulation systems can reduce heating needs by up to 70% in residential and commercial buildings.

2. Superior Fire Resistance for Safer Buildings

Roof areas are often close to external fire sources or flammable materials.
CCEWOOL® Stone Wool Board HD is made from non-combustible materials, with fire resistance exceeding 1000°C. It offers excellent passive fire protection and effectively slows fire spread, improving building safety.

3. Soundproofing for Better Living and Working Environments

Roofs are exposed to noise from wind, rain, footsteps, or mechanical equipment.
The dense structure of stone wool board absorbs sound vibrations, reducing noise intrusion into interior spaces. This is especially beneficial when converting attic spaces into bedrooms or living areas.

4. Durable and Versatile for Various Roof Structures

CCEWOOL® Stone Wool Board HD maintains excellent dimensional stability and long-term R-value, with no sagging or deformation over time. Its strong moisture resistance allows it to remain effective even when other roofing materials are replaced, adding long-term value and sustainability.

Versatile Applications in Roof Insulation

Whether for flat or sloped roofs, stone wool insulation provides precise and efficient thermal control:
•Steel structure roofs: Quick installation, strong adaptability, improved thermal and fire performance.
•Concrete roof systems: Long-lasting, high compressive strength, excellent insulation and soundproofing.
•Attic/rafter line insulation: Supports space conversion for bedrooms, offices, and other functions.
•Green roofs/terraces: Enables vegetation while regulating heat, enhancing comfort and ecological value.

Roof insulation is not just about energy saving—it’s also about space utilization, building safety, and living comfort. Choosing CCEWOOL® Stone Wool Board means choosing a core insulation material that stands the test of time. Made from natural stone, its high-performance structure meets modern building needs for thermal, fire, and acoustic control, while supporting the development of sustainable architecture.
