Open-Cell Spray Foam in Dublin, OH

In Dublin, Open-Cell Spray Foam is the right product for vented attic-floor retrofits, interior partition wall sound assemblies, and any application where vapor permeability is a design requirement rather than a defect. The install is low-density (0.5 lb) water-blown open-cell foam at R-3.7 per inch, vapor-permeable and sound-dampening, applied to interior partition walls (for sound dampening) and unconditioned attic floors (where vapor permeability matters).

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 open-cell spray foam in Dublin. We spec open-cell at the right surfaces only, such as interior partition walls for sound assemblies, attic floors over vented attics, and other vapor-permissive applications.

Open-cell foam does not function as a vapor retarder; in Climate Zone 5A, it should never be sprayed directly to roof decks unless paired with a separate vapor-control strategy designed by the project envelope engineer. Permitting in Dublin routes through the local OH building department, and Climate Zone 5A R-value targets apply across the entire Columbus metro.
