Product Description

Johns Manville Formaldehyde-free Climate Pro blow-in loose-fill fibreglass insulation is a premium alternative to cellulose. It‘s blown into attics, nonconforming spaces and hard-to-reach areas, like corners, edges and around framing. When it’s applied to the recommended thickness and specifications, it improves energy efficiency. And unlike cellulose, it won’t settle, decay or provide food for animals or microbes. It’s effective for the life of the home.
