In building thermal management systems, the roof is one of the most critical areas for heat exchange. This is especially true for sloped roof structures, which, without a continuous and reliable insulation layer, can easily lead to heat loss and external noise infiltration. The high-density, high-performance Rock Wool Insulation Board, with its excellent thermal insulation, acoustic absorption, and fire resistance, has become the preferred insulation material for sloped roof systems in modern residential and commercial buildings.

CCEWOOL® Rock Wool Insulation Board is made from natural rock wool with a dense structure and outstanding thermal stability, specifically designed for sloped roofs and attic spaces. It can be installed between, beneath, or above the rafters, allowing flexible adaptation to various roofing structures and effectively building a continuous insulation layer. Whether for attic renovations, storage space insulation, or green roof upgrades, this product delivers long-term and effective thermal protection.

Why Choose Rock Wool Insulation Board for Sloped Roof Insulation?

1.Improved Energy Efficiency, Year-Round Indoor Temperature Balance
In cold or temperate climates, uninsulated sloped roofs can cause up to 25% of a building’s heat loss. In hot climates, roof radiation increases cooling loads and reduces air conditioning efficiency.
CCEWOOL® Rock Wool Insulation Board has a very low thermal conductivity, significantly reducing heat transfer through roof structures. It helps retain indoor warmth in winter and blocks external heat in summer, effectively reducing HVAC operation, enhancing thermal comfort, and lowering energy consumption.
2.Excellent Acoustic Performance for a Quieter Environment
With increased urbanization comes more noise from traffic and industry. Roof areas are particularly exposed to disturbances from wind, rain, equipment, and ambient noise.
Natural rock wool has an open fiber structure that provides excellent sound absorption. It effectively reduces structure-borne and airborne noise, making it ideal for buildings near highways, railways, or airports, and helps create quieter and more focused residential and working environments.
3.Superior Fire Resistance Enhances Roof System Safety
The roof, being the upper part of a building, is a critical area for fire spread. Fire resistance is essential.
CCEWOOL® Rock Wool Insulation Board is a non-combustible material withstanding temperatures over 1000°C. In case of fire, it forms an effective fire-resistant barrier, preventing flames from spreading to roof structures. It is ideal for residential and commercial buildings with high fire safety requirements and significantly improves the fire rating of the overall structure.
4.Durable and Moisture-Resistant
Moist environments can cause insulation layers to absorb water, mold, or corrode, compromising insulation performance and building longevity.
Rock wool has excellent moisture resistance and dimensional stability. It does not absorb water or decay and maintains its integrity and thermal resistance in all climates. For complex shapes or special installation conditions, it can be reinforced and secured using rock wool insulation with wire mesh, increasing strength and durability—ideal for heavy-load or long-maintenance roof structures.

Typical Applications for Sloped Roof Insulation:

•Between-rafter insulation: Suitable for new or retrofit projects, filling insulation between rafters to form a continuous insulation layer.
•Above-rafter/below-rafter insulation: Can be applied above the structural layer or below the ceiling layer, ideal for attic space conversions.
•Attic floor insulation: For non-livable attic spaces requiring only thermal protection without heating.
•Metal roof sandwich structures: Enhanced with rock wool insulation with wire mesh for better fixation and long-term structural performance.
Roof insulation performance directly affects the building's overall energy efficiency, comfort, and safety. With comprehensive advantages in thermal insulation, sound absorption, fire resistance, and moisture durability, CCEWOOL® Rock Wool Insulation Board is a reliable solution for sloped roof insulation systems.
Whether for energy-saving retrofits, space expansion, or improving acoustic and fire protection performance, CCEWOOL® provides stable, efficient, and long-lasting insulation support for your projects—helping create more livable and secure modern spaces.
