Wall Cavity Spray Foam in Dublin, OH

In Dublin, Wall Cavity Spray Foam is most impactful in pre-1950 homes with empty plaster wall cavities or settled fiberglass, and in 1950s-1970s drywall homes with original R-11 batts that have lost their air-seal. The install is drill-and-fill closed-cell foam through 1.5-inch access holes in each stud cavity, applied to the wall plane, the second-largest thermal surface after the attic.

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 wall cavity spray foam in Dublin. We size drill-and-fill scope to the era and cavity condition identified at the in-home assessment.

Pre-1995 wall assemblies typically have no air barrier; drill-and-fill closed-cell adds both R-19 to R-21 in a 2x4 cavity and the integrated air seal that fiberglass cannot provide. Permitting in Dublin routes through the local OH building department, and Climate Zone 5A R-value targets apply across the entire Columbus metro.
