Enovate insulating foam sealants from Honeywell are designed specifically for insulating around wall penetrations and sealing air ducts. Available in eight and 20-ounce cans, the low-expansion formula minimizes mess and clean up and means contractors do not have to worry about damage that could be caused by overexpansion. A reusable straw allows the tradesman to simply snip off an inch of the straw to start the next application.
