Rim Joist & Band Joist Foam in Hyde Park, 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 Hyde Park 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.

Hyde Park's owner-occupied stock skews heavily 1910-1940 with lath-and-plaster walls, full basements with stone or early-concrete foundations, and steep-pitched attics with rafter cavities open to the roof deck. Wall cavities are frequently empty or hold settled fiberglass batts from a 1970s-80s retrofit. That housing profile shapes our typical scope for rim joist & band joist foam in Hyde Park. 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 Hyde Park 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.
