The Blow-in-Blanket insulation system is your best choice, because it is the most energy-efficient and cost-effective insulation system available. The Blow-in-Blanket System is a patented insulation system that blows the insulation into place behind netting. A thin coating of adhesive holds the insulation in place giving the best seal possible around ducting, junction boxes and in corners.

High-quality fiberglass batting would be your insulation of choice for adding to or replacing insulation in attics, walls, floors and ducts.

Certainteed and Johns Manville both recognize the Blow-in-Blanket (BIB) system as the best way to insulate side walls.
