Wall Cavity Spray Foam in Cincinnati, OH

In Cincinnati, Wall Cavity Spray Foam is most impactful in pre-1950 homes with empty plaster wall cavities or settled fiberglass, and in 1950s-1970s drywall homes with original R-11 batts that have lost their air-seal. The install is drill-and-fill closed-cell foam through 1.5-inch access holes in each stud cavity, applied to the wall plane, the second-largest thermal surface after the attic.

Cincinnati proper spans pre-Civil-War brick rowhouses in Over-the-Rhine through 2010s infill in Northside and Pleasant Ridge. Most owner-occupied stock is 1920s-1960s with plaster or early drywall walls, basement furnaces, and partially-finished attics. The Cincinnati Arch geology under the city is fractured limestone and shale, which drives the radon and basement-moisture profile that shapes most retrofit decisions. That housing profile shapes our typical scope for wall cavity spray foam in Cincinnati. We size drill-and-fill scope to the era and cavity condition identified at the in-home assessment.

Wall-cavity foam in Hamilton County finds its best candidates in Hyde Park, Norwood, and Mt. Lookout's pre-war plaster-wall homes, many with empty stud cavities behind original lath and plaster, while Anderson Township, Blue Ash, and Montgomery's mid-century drywall homes typically hold original R-11 fiberglass batts that have settled and lost their air-seal. Both drill-and-fill through a small access patch, adding the R-19 to R-21 the Climate Zone 4A wall target calls for along with the air-seal fiberglass alone cannot provide.

Pre-1995 wall assemblies typically have no air barrier; drill-and-fill closed-cell adds both R-19 to R-21 in a 2x4 cavity and the integrated air seal that fiberglass cannot provide. Permitting in Cincinnati routes through Hamilton County Building Department (or the local municipality where applicable), and Climate Zone 4A R-value targets apply across the entire Cincinnati metro including both sides of the river.
