In regions with significant temperature fluctuations, pitched roofs are among the most critical areas for heat loss in buildings. Studies show that uninsulated pitched roofs can account for up to 25% of total heat loss, significantly compromising indoor comfort and overall building energy efficiency.

To address this issue, CCEWOOL® Stone Wool Insulation Board HD offers an R-value of 19 at a thickness of 5 inches, meeting energy efficiency standards for pitched roof insulation systems across many regions in North America. It is ideal for both new construction and renovation projects, helping improve the overall energy performance of buildings.

CCEWOOL® Stone Wool Insulation Board HD features high density, excellent breathability, and dimensional stability, making it a reliable solution for pitched roof systems:
Superior thermal insulation: The low thermal conductivity fiber structure retains heat in winter and blocks heat in summer, consistently reducing HVAC energy consumption.
Class A non-combustible, fire safe: Made from natural basalt, it withstands temperatures up to 1000°C and meets stringent building fire safety codes.
No sagging or deformation: With uniform density and structural integrity, the board adapts to varying roof slopes and remains stable over time.
Moisture-resistant and mold-proof: Its breathability and hydrophobic properties minimize condensation risks and enhance overall roof system durability.
