Foam Matched to the Heat and Humidity
Spray foam insulation pays off in Warner Robins where heat and humidity get into a house: the underside of the roof deck over attic ducts, crawl space walls and rim joists, bonus room kneewalls and the panels of steel buildings. Foam goes on wet, expands into gaps and cures in place, so one coat insulates and stops air at the same time. That air sealing is what makes a difference in a climate where July afternoons average about 92F.
Open cell vs closed cell
Open-cell foam cures soft and light and expands to many times its liquid volume. HomeGuide rates it at R-3.5 to R-3.7 per inch. It seals air well, deadens sound and lets water vapor pass, which is why it is often used under the roof deck in a sealed attic. Closed-cell foam cures dense and rigid at R-5 to R-7 per inch, slows vapor and does not soak up water, so it goes where moisture is a concern: crawl space walls, the band joist, floors over damp ground and metal buildings.
Sealed attics over attic ductwork
A lot of Warner Robins homes have the air handler and ductwork in the attic. In August that attic can run far hotter than the outdoors, and every duct leak pulls hot, humid air into the house. Spraying foam under the roof deck and on the gable walls brings the ducts inside the insulated space. It is not always the cheapest choice, and the HVAC setup and any combustion appliances in the attic have to be checked first, but it often fixes a hot upstairs that nothing else has.
Termites and inspection access
All of Georgia has a high probability of subterranean termites, and a 2019 proposal to the state's codes committee from the Spray Polyurethane Foam Alliance recommended leaving the sill plate and the top 3 inches of the foundation wall exposed so they can be inspected. We plan crawl space and foundation foam so the sill area stays visible and tell you how we have left it.
Where foam is not the answer
Foam does not fix leaks. A roof, plumbing or foundation leak gets repaired first, or foam just hides the damage. A wide-open attic floor is usually handled for less with air sealing and blown-in insulation. We say so when that is the case.

Spray Foam Insulation Questions
Should I use open-cell or closed-cell under my roof deck?
Open-cell is the common choice under roof decks in Middle Georgia because it seals air well at lower cost. Closed-cell gives more R-value per inch. We look at your roof framing and HVAC before recommending one.
Will spray foam in my attic void my shingle warranty?
Some shingle makers have specific requirements for unvented attics. Check your roofing warranty before sealing the attic; we can tell you what to ask.
How long do we need to stay out after spraying?
HomeGuide's guidance is 24 hours or more.
Does spray foam attract termites?
Termites do not eat foam, but foam can hide their mud tubes. That is why we leave the sill area visible for inspection.
