Spray foam insulation is a type of insulation that’s applied on-site as liquid, then expands to fill and seal all the nooks and crannies in your walls, ceilings and foundation. It also conforms to the unique design of your home, allowing you to create an airtight seal that reduces energy loss and keeps heat in during colder months and out during warmer ones.

It impacts the conduction and the convection that are the two forces that impact your home’s energy efficiency. This makes it more effective than fiberglass and cellulose insulation.

During installation, your spray insulation expert will hose down the area to be sprayed and then apply a thin layer of the foam to studs, joists and wall cavities. The foam expands as it dries, sealing air leaks and creating an insulating barrier that’s more effective than traditional fiberglass.

Top Reasons to Choose 316 Insulation for Your Spray Foam Projects

Open and closed-cell spray foam are available, and each has its own advantages and disadvantages. Open-cell spray foam, which uses carbon dioxide or water as its propellant, has small pockets that help it resist heat flow and absorb sound. It can provide a high R-value, up to about R-13 in 2×4 walls and up to R-19 in 2×6 walls. It does not repel moisture or vapor, so it may require the addition of a vapor barrier in certain applications.

Closed-cell spray foam has much higher R-values and acts as a vapor barrier, but it is more expensive per board foot than open-cell. This type of spray foam can be used in new construction and retrofitting existing walls. It can be sprayed into attics, crawl spaces and rim joist in existing homes and pole barns. It will off-gas large amounts of volatile organic compounds during spraying and curing, so it’s best for professional technicians to install this type of insulation.
