Blown-In Insulation Costs. Blown-in insulation is one of the most common ways to insulate the attic, crawl space, or walls of a home. The average cost is about $1,358, with most homeowners spending between $889 and $1,896, but this is dependent on whether the work is done by the homeowner or by a professional.
The R-factor of blown-in fiberglass is usually 2.3 to 2.8 per inch of material. Once installed and expanded to the uniform, manufactured thickness, batts offer a known R-factor. Blown-in insulation thickness can vary in an attic space. This will lead to non-uniform R-values.he total cost to have the fiberglass blown-in by professionals was $0.40 per square foot or $600. I then called the local retail outlet to price batt insulation. The cost of just the material was $0.45 per square foot!
