1.2 cu. ft. Approximate Coverage—Insulation that covers 1.2 cu. ft. is best for touch-up and repair jobs.

12 cu. ft. Approximate Coverage—Insulation that covers 12 cu. ft. comes out in a smooth line, so they're useful for filling and sealing gaps to prevent airflow.

12.3 cu. ft. Approximate Coverage—Insulation that covers 12.3 cu. ft. sprays farther and more thoroughly than other foam insulation. Use them to fill cavities, channels, framing, and hollow tubing.
