Bob writes from Ft. Mitchell, Kentucky: "I have 5 inches of blown in insulation in my home. My home was built in 1972. What kind of insulation can I put down over this insulation?"

Answer: You can have more fiberglass insulation blown into the attic or lay fiberglass batts over the existing insulation. For more information on this topic, check the Owens Corning Web site page for Adding Insulation to an Attic.
