The most common insulation materials are fiberglass, cellulose and foam. Insulation types include loose fill, batts, rolls, foam board, spray board and vapor barriers. Tip: The type of insulation you need depends on which is currently installed and the required R-value. Blown-in/loose fill. 1  Usually made of fiberglass or cellulose (recycled paper fiber) 2  Blown or sprayed into place with pneumatic equipment. 3  Ideal for hard-to-reach areas such as attics.  Can fill wall cavities and installed over existing insulation.
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!
