Wall Cavity Spray Foam in Hilliard, OH

In Hilliard, 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.

Hilliard's housing stock is overwhelmingly post-1985 subdivision construction, and the newest of those homes sometimes already have closed-cell foam at the rim joist from the original build. Older Hilliard homes, concentrated in the small historic Main Street core, need fuller attic and wall retrofits to reach the Climate Zone 5A R-49 to R-60 attic target that the newer subdivisions were built closer to already. Whole-home packages are more common on the older stock, while newer subdivision homes typically need only selective attic or rim-joist work. Hilliard sits on the flat glacial till plain west of the Scioto River, with the river's Griggs Reservoir pool a few miles east of the city. That housing profile shapes our typical scope for wall cavity spray foam in Hilliard. We size drill-and-fill scope to the era and cavity condition identified at the in-home assessment.

Wall-cavity foam in Franklin County finds its strongest candidates in Bexley, Clintonville, and Grandview Heights' pre-war streetcar-suburb bungalows and foursquares, many with empty plaster cavities from the 1900s through 1930s, while Whitehall's postwar ranches typically carry original R-11 batts that benefit from the added air-seal. Blacklick's post-1995 subdivision stock rarely needs the work; the Climate Zone 5A wall target here leans toward R-20 cavity fill or R-13 plus continuous exterior R-5.

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 Hilliard routes through the local OH building department, and Climate Zone 5A R-value targets apply across the entire Columbus metro.
