Closed-Cell Spray Foam in Westerville, OH

In Westerville, Closed-Cell Spray Foam is the right product whenever the surface sits below grade, touches masonry, or needs both R-value and vapor-barrier performance from a single material. The install is high-density (1.75-2.0 lb) closed-cell foam at R-7 per inch with vapor-barrier properties above 2 inches, applied to vapor-critical surfaces: rim joists, crawl-space walls, below-grade walls, and roof decks in conditioned-attic designs.

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 closed-cell spray foam in Westerville. We spec closed-cell at the specific vapor-critical surface identified during the assessment, whether that is the rim joist, crawl walls, basement walls, or roof deck in a conditioned-attic design.

Closed-cell foam meeting IBC and IRC ignition-barrier requirements typically holds an ICC-ES evaluation report; the closeout package should identify the specific ESR number for the product line installed. Permitting in Westerville routes through the local OH building department, and Climate Zone 5A R-value targets apply across the entire Columbus metro.
