Attic Protector®
Johns Manville Attic Protector® blown-in fiber glass insulation is a premium alternative to cellulose. It's blown in to cover attics and hard-to-reach areas within attics, like corners, edges and around framing. When it's applied to the recommended thickness and specifications, you can be assured that your home is energy-efficient, with minimal heat loss. And unlike cellulose, it won't settle, decay or provide food for animals or microbes. It's effective for the life of your home.
