Rockwool Comfortbatt R15 3.5"x15.25"x47"

Rockwool Comfortbatt R15 3.5"x15.25"x47"


ROCKWOOL COMFORTBATT® stands as a semi-rigid stone wool batt insulation tailored for use in exterior wood and steel stud applications, whether it's in new construction or renovation projects. This innovative insulation solution boasts a flexible edge that's ingeniously designed to compress upon insertion, then rebound to expand against the frame studs, ensuring complete coverage. This flexibility guarantees that the specified R-value is achieved and maintained.
COMFORTBATT® is recognized for its non-combustible and fire-resistant properties. It refrains from producing toxic smoke or promoting flame spread, even when directly exposed to fire. Additionally, it offers water and moisture resistance, along with excellent sound-absorbing characteristics. Installing COMFORTBATT® is a highly effective means of enhancing a home's energy efficiency. It proudly holds the GREENGUARD Gold Certification and contributes to a healthier indoor environment.
