CertainTeed InsulSafe SP Premium Blowing Insulation is pneumatically installed fiberglass loose-fill insulation for thermal and acoustical performance. It is especially suited to open attic areas where blown fibers can fill around framing and irregular spaces to create a continuous insulation blanket.

CertainTeed lists up to 40% recycled content, resistance to moisture absorption and fungus growth, a Limited Lifetime Warranty and current BABA compliance. Installed R-value and bag coverage depend on the manufacturer's required depth/density chart, so use the current coverage table for material takeoff.
