PRODUCT DESCRIPTION

About This Product
ROCKWOOL R-23 Rockwool 5-1/2 in. x 15-1/4 in. x 47 in. (39.8 sq. ft.) Comfort Stone Wool Insulation Batt is a high-performance stone wool insulation designed for use in exterior wood and steel stud walls, as well as exposed floors, basements, crawlspaces, and attic applications. It provides reliable thermal performance while helping improve overall energy efficiency.


Featuring a flexible edge, Comfortbatt compresses during installation and expands to fit snugly within stud cavities, ensuring a tight friction fit without gaps. This helps maintain consistent R-value over time. Made from durable stone wool, it offers excellent fire resistance, moisture resistance, and sound absorption, making it a versatile solution for residential and commercial insulation needs.




Key Features



  • Flexible edge design expands to fit tightly in stud cavities for optimal thermal performance

  • Easy to install and cut with a serrated knife for a precise fit around obstructions

  • Friction-fit installation prevents sagging over time

  • Noncombustible and fire-resistant with a melting point above 1000°C

  • Water-resistant material repels moisture for added durability

  • Excellent sound absorption due to high-density fiber structure

  • Made from natural stone wool, a sustainable and abundant material

  • GREENGUARD Gold certified for low emissions

  • Chemically inert and free of CFCs and HCFCs

  • Inorganic material resists mold, mildew, and fungal growth
