Expert Verdict — Reviewed by the SuperArbor Pro Desk
Blown fiberglass is a fast way to top up an attic to a modern R-value, but performance depends on even depth, so use depth rulers or marked stakes while blowing. Keep insulation off recessed fixtures rated for contact and maintain baffled airflow at the soffit. Order about 10 percent more bags than the chart indicates to cover settling and irregular attic shapes.
Wear a respirator, eye protection and coveralls when blowing fiberglass insulation, and keep the material away from non-IC-rated recessed light fixtures and heat sources.
Order Owens Corning AttiCat fiberglass blow-in insulation by the 33 lb bag for your attic project.
