Wall Cavity Spray Foam in Granville, OH

In Granville, 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.

The stone and frame houses in Granville's historic district were built with balloon framing, plaster walls, and open rafter attics, and the district's preservation rules generally rule out exterior work, which pushes insulation retrofits toward interior and attic-only approaches. The subdivisions built at the village's edges since the 1980s use standard batt-insulated framing with vented attics, a straightforward retrofit by comparison. Granville sits in the valley of Raccoon Creek and the South Fork Licking River, and the village's historic district limits exterior alteration on much of the pre-1950 core. That housing profile shapes our typical scope for wall cavity spray foam in Granville. We size drill-and-fill scope to the era and cavity condition identified at the in-home assessment.

Licking County's best wall-cavity candidates are the small pre-war village cores in Granville and Johnstown, where empty or settled cavities behind original plaster are common, while Pataskala's fast-growing post-1990s subdivision stock generally already has effective wall insulation.

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.
