Spray insulation consists of closed- and open-cell polyurethane foam that’s applied by spraying it into the space to be insulated. It can be sprayed into attics, crawl spaces and basement rim joist in existing homes; stud cavities, knee walls, eaves, overhangs and pole barns in new construction; and concrete block and poured wall foundations in addition to garages. The foam comes in a variety of R-Values and density levels. Open-cell spray foam generally costs less than closed-cell foam. Holt MI

Homeowners can purchase DIY kits to install spray foam themselves, but these typically only include the foam and the machinery to apply it, and exclude labor, protective equipment and plastic sheeting. The foam gives off volatile organic compounds (VOCs) as it dries, and homeowners should use masks and full-face respirators during application.
