Performance attributes

Owens Corning’s blown-in fiberglass insulation is designed for fast and easy installation, allowing most attics to be insulated in as little as two hours with the AttiCat® machine. Its expanding fiberglass material fills gaps and hard-to-reach spaces with minimal mess; the loose-fill insulation releases and finishes conditioning and expansion while traveling through the hose inside the machine before application. Once installed, AttiCat® insulation has virtually no settling, which helps to maintain its R-value over time.
