Closed-Cell Spray Foam in Dublin, OH

In Dublin, 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.

Dublin's post-1995 subdivision stock was built to the era's energy code with builder-grade fiberglass batts in the walls and attic floor, OSB wall sheathing, and largely uninsulated rim joists that are a common closed-cell foam retrofit target. The small Historic Dublin core along the Scioto holds a handful of older frame structures with balloon framing and empty wall cavities that need a drill-and-fill approach rather than a standard batt replacement. Attic-mounted HVAC equipment is common in the newer subdivisions, which changes where the conditioned-attic boundary needs to sit. Dublin straddles the Scioto River, and much of its post-1995 subdivision growth sits on the river's floodplain terraces and the bluffs above them. That housing profile shapes our typical scope for closed-cell spray foam in Dublin. 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 Dublin routes through the local OH building department, and Climate Zone 5A R-value targets apply across the entire Columbus metro.
