Rim Joist & Band Joist Foam in Granville, OH

In Granville, Rim Joist & Band Joist Foam is the single highest-ROI insulation upgrade 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. The install 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.

The stone and frame houses in Granville's historic district were built with balloon framing, plaster walls, and open rafter attics, and the district's preservation rules generally rule out exterior work, which pushes insulation retrofits toward interior and attic-only approaches. The subdivisions built at the village's edges since the 1980s use standard batt-insulated framing with vented attics, a straightforward retrofit by comparison. Granville sits in the valley of Raccoon Creek and the South Fork Licking River, and the village's historic district limits exterior alteration on much of the pre-1950 core. That housing profile shapes our typical scope for rim joist & band joist foam in Granville. 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.

Licking County rim-joist scope covers Granville and Johnstown's small pre-war village cores, almost universally bare at the rim joist, and Pataskala's fast-growing post-1990s subdivisions, where coverage often already exists from original construction and the job is verification and top-up.

IECC R402.1.1 requires R-13 minimum at the rim joist for Climate Zone 5A. Two inches of closed-cell foam delivers R-13+ and seals the band joist air leakage path in one pass. Permitting in Granville routes through the local OH building department, and Climate Zone 5A R-value targets apply across the entire Columbus metro.
