You can expect to get about 3.5 sqft of coverage from the average 16oz can of canned foam. Our Foam Beaks are made in the USA out of ABS plastic, so they are tough and durable.

The Foam Beak works great when you want to add more foam insulation to your hot tub, or spa. We have used these to insulate the back-side of a bathtub before installation (takes approximately 4-5 cans to cover the back-side of an average size bathtub). Use the Foam Beak to insulate just about anywhere you wish. Have a cold attic access panel? Or how about that drum that you use at parties to keep a keg cold? The uses are endless
