In a standard 16" oc Wall, what is the yield of this can?

Thank you for the question. Unfortunately, OSI QUAD 16oz. Foam is not designed or intended to fill wall cavities as described but instead to fill or seal gaps, cracks and holes that are commonly found around the home. Coverage for this product is measured only in lineal feet of dispense bead. The yield for a 16 oz. can when used with a gun application is approximately 508 feet (154 meters) based on a ½” x ½” joint. When used with the accompanying straw the yield is approximately 386 feet (117 meters) based on a ½” x ½” joint.
