One of the best high-performance insulation materials on the market today for Illinois homeowners is spray foam insulation. Made of polyurethane, and available as an ‘open’ or ‘closed’ cell foam, spray foam insulation is well-suited to retrofit situations as well as new construction projects through Peoria, Bloomington, Pekin, and Morton.
- Open cell spray foam has a slightly higher R-value as fibrous insulation, but it is better at sealing up air leakage than fiberglass batts are. Open cell spray foam insulation’s R-value is, on average, R-3.7 per inch of thickness.
- Closed cell spray foam has a much higher R-value per inch, and can act as both an air barrier and a vapor barrier. Closed cell spray foam’s R-value per inch is, on average, R-6.5 per inch of thickness.
Regardless of the kind of spray foam you choose for your insulation in Peoria, IL, both types must be installed by trained professionals.
How Is Open & Closed Cell Spray Foam Installed?
Polyurethane foam insulation is applied using a spray gun that combines two separate components which expand into a foam. You can use spray foam for wall insulation, floor insulation, or to fill ceiling cavities that need to be insulated.
Spray foams are great for getting into tight and oddly-shaped spaces. Spray foam products can provide higher insulation values in places that really need them, like the eaves in older homes, where other materials with lower R-values per inch can’t provide enough thermal protection.
Spray foams also help to reduce outside noise levels, creating a quieter, more comfortable indoor environment. In addition, the materials they are made of do not appeal to most insects and animals, meaning your home won’t inadvertently turn into a home for unwanted rodents and pests, leading to indoor air quality issues.
Closed cell foam is more expensive than open cell foam because it is denser and requires more material. However, it can be the best investment in your house since it acts as an air barrier and a vapor barrier when installed properly.

At AAA Northgate One Hour Heating & Air Conditioning®, we know there is never one solution to a cost-effective energy upgrade that leads to lower bills. That’s why we also install dense-pack and blown cellulose insulation.
In some cases, the best insulation upgrade in an attic is a combination of closed cell foam and cellulose. The expanding foam is applied in the proper thickness to provide a complete air barrier in the attic, and the cellulose ‘tops up’ the insulation level to the required R-value.
