Wall Cavity Spray Foam in Bexley, OH

In Bexley, 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.

Bexley was built out mostly between 1908 and 1940 with large Tudor Revival, Colonial Revival, and American Foursquare houses along Main Street and Broad Street, on lath and plaster walls with full basements and steep original rafter attics. Wall cavities behind that original plaster are frequently empty, and the closed attic construction on many of the largest homes limits blown-in access from above. A drill-and-fill retrofit through the exterior siding is the common approach that avoids disturbing the original plaster. Bexley's eastern edge runs along Alum Creek on the flat glacial till plain typical of Franklin County, without the ravine lots found along the Olentangy corridor to the north. That housing profile shapes our typical scope for wall cavity spray foam in Bexley. We typically run drill-and-fill closed-cell foam through plaster access patches, preserving the historic interior surfaces while filling empty stud cavities.

Wall-cavity foam in Franklin County finds its strongest candidates in Bexley, Clintonville, and Grandview Heights' pre-war streetcar-suburb bungalows and foursquares, many with empty plaster cavities from the 1900s through 1930s, while Whitehall's postwar ranches typically carry original R-11 batts that benefit from the added air-seal. Blacklick's post-1995 subdivision stock rarely needs the work; the Climate Zone 5A wall target here leans toward R-20 cavity fill or R-13 plus continuous exterior R-5.

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