Attic Spray Foam Insulation in Montgomery, OH

Attic Spray Foam Insulation 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. In Montgomery specifically, the service 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.

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 attic spray foam insulation in Montgomery. We typically spray attic-floor open-cell over the ceiling drywall to seal the largest air-leakage plane in mid-century vented-attic stock.

IECC Climate Zone 4A 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 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.
