About Columbus Spray Foam Pros

I'm Sam Reynolds, and spray foam in Central Ohio is my specialty: the product chemistry, the code sections, and the building science behind a correct install, in terms a Columbus homeowner can actually use when comparing quotes from local contractors.

Most of what I know is specific to Central Ohio. Columbus sits in IECC Climate Zone 5A with roughly 5,500 to 5,800 heating degree days a year, a full zone colder than Cincinnati, so winter air leakage rather than summer heat is where most homes here lose money. The housing stock matters just as much. Pre-1930 frame and masonry homes in German Village, Victorian Village, and Grandview Heights often have empty wall cavities, and the 1940s to 1970s ranches and capes in Clintonville, Worthington, and Whitehall usually have decades-compacted blown cellulose sitting well below the Energy Star Zone 5 attic target of R-49 to R-60. Freeze-thaw cycling and reliable snow cover also put ice damming on the list of problems a correctly detailed roof-deck assembly can solve here, which is not true in every Ohio market.

The standards I know best are the ones a homeowner can check for themselves. BPI (Building Performance Institute) credentialing is the de facto Columbus standard for foam installers because it covers blower-door testing, combustion safety, and moisture management, not just spray technique. ICC-ES evaluation reports (the ESR numbers on a product data sheet) show a foam system has been evaluated for code use. IRC R316, as adopted by the Ohio Residential Code, is the thermal-barrier rule that decides whether your attic gets drywall or an intumescent coating such as DC315. ASHRAE 62.2 is why a house tightened below roughly 5 ACH50 needs mechanical ventilation. If you read nothing else before signing a quote, read those four.
