Blow-in cellulose insulation has been around since the 1920âs and consists predominantly of recovered or recycled newsprint and/or corrugated cardboard, treated with a fire retardant. Three main types of blow-in cellulose insulation are used in residential application: loose fill, stabilized, and wall-cavity spray.

There are a number of different materials such as fiberglass and cellulose as well as a number of different forms such as batting and blown in. The common denominator among varieties of insulation is the R-value. R-value is a measurement of thermal resistance and measures the ability of heat to transfer from one side of an object to another. As a benchmark, one inch of solid wood has an R-value of 1.
