Chris writes from Venetia, Pennsylvania: "I would like to add insulation to my attic on top of the existing blown-in cellulose. The plan is to use rolls run perpendicular to the floor joists. Is there a pourable product available to eliminate the need to cut 15" x 6" pieces to fit between the rafters where they meet the floor joists?"

Answer: Owens Corning does manufacture blown-in FIBERGLAS™ Insulation but it is not "pour-able." The loosefill insulation the company makes is blown in using a machine that fluffs it up to assure good thermal performance. Owens Corning loosefill or blown-in insulation is generally installed by professional contractors
