Attic Spray Foam Insulation in Westerville, OH

In Westerville, Attic Spray Foam Insulation works hardest in older homes with settled cellulose or empty attics, and in homes with HVAC equipment in the attic where roof-deck foam converts the attic to a conditioned space. The install is closed-cell at the roof deck (R-7 per inch) or open-cell at the attic floor (R-3.7 per inch), applied to the attic plane, sealing the largest single thermal surface in most homes.

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 attic spray foam insulation in Westerville. We size the roof-deck or attic-floor scope to the specific HVAC layout in each home, identified at the in-home estimate.

IECC Climate Zone 5A target is R-49 attic minimum for retrofit (R-60 for new construction and major additions). Closed-cell at 7-8 inches or open-cell at 13-14 inches hits R-49. Permitting in Westerville routes through the local OH building department, and Climate Zone 5A R-value targets apply across the entire Columbus metro.
