Attic Spray Foam Insulation in Dublin, OH

In Dublin, 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.

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 attic spray foam insulation in Dublin. 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 Dublin routes through the local OH building department, and Climate Zone 5A R-value targets apply across the entire Columbus metro.
