Wall Cavity Spray Foam in Montgomery, OH

Wall Cavity Spray Foam 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. In Montgomery specifically, the service 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.

Montgomery's residential core is 1960s-1990s single-family with drywall walls, vented attics, and partial or full basements. Cathedral-ceiling great rooms became common in the 1980s-90s builds. That housing profile shapes our typical scope for wall cavity spray foam in Montgomery. We run drill-and-fill through drywall access patches into stud cavities with original R-11 fiberglass, adding both R-value and the air-seal that fiberglass alone cannot provide.

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 Montgomery routes through Hamilton County Building Department (or the local municipality where applicable), and Climate Zone 4A R-value targets apply across the entire Cincinnati metro including both sides of the river.
