About Cincinnati Spray Foam Pros

I'm Sam Reynolds, and spray foam in Greater Cincinnati is my specialty: the standards a correct install follows, the products on the trucks, and the housing stock the foam goes into. When a quote is sitting on the kitchen table, these are the numbers that matter: what closed-cell foam at roughly R-7 per inch buys you compared to open-cell at roughly R-3.7, why Energy Star puts the attic retrofit target at R-49 for our climate zone and R-60 for additions, and what the thermal barrier requirement means for foam that would otherwise sit exposed in a living space.

Cincinnati is IECC Climate Zone 4A under the 2021 IECC, and the housing stock here changes enough from one neighborhood to the next that the right foam answer changes with it. Those differences are where I have spent most of my time: the 1920s Hyde Park and Norwood homes with plaster walls and empty cavities, the pre-war Covington and Newport row houses on the same Cincinnati Arch geology, the Mariemont Tudors with cathedral ceilings, and the newer West Chester and Liberty Township subdivisions that often already have closed-cell foam at the rim joist. In the older stone-basement and crawl space homes around Fort Thomas and the Ohio River corridor in Anderson Township, moisture usually decides the plan before R-value does.

The standards I know best are the ones that determine whether a foam job holds up. BPI building science credentialing, which tests an installer on substrate prep, mix-ratio verification, and moisture management rather than just on running a spray gun. ICC-ES product evaluation reports, which are the documents a Hamilton, Butler, Warren, or Clermont county inspector references to confirm a specific foam is code-approved for your assembly. ASHRAE 62.2, for when the envelope gets tight enough that the house needs mechanical fresh air. And ANSI/BPI 1200-S combustion safety testing, which matters in any home with a gas furnace or water heater once the air leakage drops. Everything on this site is built to help you ask a contractor sharper questions before you sign.
