Attic Spray Foam Insulation in Madeira, 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 Madeira 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.

Madeira's owner stock is mostly 1950s-1970s ranch and split-level with drywall walls, vented attics, and crawl spaces or partial basements. Original R-11 fiberglass batts are common in both attic and wall cavities; rim joists are typically uninsulated. That housing profile shapes our typical scope for attic spray foam insulation in Madeira. 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 Madeira 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.
