Attic Spray Foam Insulation in Columbus, OH

In Columbus, 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.

Columbus proper spans German Village and Italian Village brick rowhouses from the 1880s through Hilltop and Linden housing built for early-1900s streetcar and factory workers, mid-century ranch neighborhoods further out, and 2000s condo and infill construction downtown and in the Short North. The oldest brick rowhouse stock typically has masonry walls with little to no cavity insulation, while the mid-century ranch belt carries whatever fiberglass batts the original builder installed. Rim joists across the pre-1995 majority of the city are a near-universal retrofit gap regardless of neighborhood. Downtown Columbus sits at the confluence of the Scioto and Olentangy rivers, with the rest of the city spread across the flat glacial till plain typical of central Ohio. That housing profile shapes our typical scope for attic spray foam insulation in Columbus. We size the roof-deck or attic-floor scope to the specific HVAC layout in each home, identified at the in-home estimate.

Franklin County attic conditions track Columbus's own housing range: Bexley, Clintonville, and Grandview Heights' pre-war streetcar-suburb bungalows and foursquares often have thin original attic insulation, Whitehall's postwar ranches typically carry settled fiberglass batts, and Blacklick's post-1995 subdivision stock usually already meets a code-era baseline. All three need to reach the Climate Zone 5A retrofit target of R-49 (R-60 for additions), the same numeric target as the Cincinnati market but driven by a longer heating season.

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 Columbus routes through the local OH building department, and Climate Zone 5A R-value targets apply across the entire Columbus metro.
