Rim Joist & Band Joist Foam in Blue Ash, OH

Rim Joist & Band Joist Foam is 2-3 inches of closed-cell foam at the rim and band joist where the foundation meets the framing, applied to the rim joist, which sits at the worst air-infiltration band in most homes. In Blue Ash specifically, the service is the single highest-ROI insulation project for any home built before 1995, where the rim joist is almost always uninsulated and acts as the stack-effect chimney that drives winter heat loss.

Blue Ash housing skews to 1960s-1990s single-family built for the corporate-corridor workforce. Drywall walls, vented attics, partial basements. Many homes have had at least one HVAC replacement that left ductwork in the attic. That housing profile shapes our typical scope for rim joist & band joist foam in Blue Ash. We spray full closed-cell coverage at the rim and band joist, the highest-ROI single project on virtually every pre-1995 home in the metro.

IECC R402.1.1 requires R-13 minimum at the rim joist for Climate Zone 4. Two inches of closed-cell foam delivers R-13+ and seals the band joist air leakage path in one pass. Permitting in Blue Ash 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.
