Wall Cavity Spray Foam in Westerville, OH

In Westerville, 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.

Westerville's historic Uptown core holds early-1900s balloon-frame housing with open wall cavities running from foundation to attic, a natural drill-and-fill closed-cell candidate. The subdivisions built up around Uptown from the 1960s through the 2000s carry standard fiberglass batts and OSB sheathing typical of their respective decades, with rim joists that were rarely insulated before the 1995 code update. Attic and rim-joist packages are the more common project on the older subdivision stock, while wall-cavity foam is reserved for the balloon-frame Uptown houses. Westerville's northeast edge borders Hoover Reservoir on Big Walnut Creek, and the rest of the city sits on the flat glacial till plain typical of central Ohio. That housing profile shapes our typical scope for wall cavity spray foam in Westerville. We size drill-and-fill scope to the era and cavity condition identified at the in-home assessment.

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