Cost of Loose-Fill Insulations



At the time this publication was written, the average loose-fill per R-value per square foot was about 0.8 cents for cellulose and rock wool and 1.1 cents for fiberglass. These prices were for materials only. The average installed price per R-value per square foot was about 1.2 cents for blown-in cellulose and rock wool and 1.3 cents for fiberglass. Because prices vary in different regions, obtain bids from several contractors or suppliers to determine the specific cost in your area.
