Rim Joist & Band Joist Foam in Hilliard, OH

In Hilliard, 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.

Hilliard's housing stock is overwhelmingly post-1985 subdivision construction, and the newest of those homes sometimes already have closed-cell foam at the rim joist from the original build. Older Hilliard homes, concentrated in the small historic Main Street core, need fuller attic and wall retrofits to reach the Climate Zone 5A R-49 to R-60 attic target that the newer subdivisions were built closer to already. Whole-home packages are more common on the older stock, while newer subdivision homes typically need only selective attic or rim-joist work. Hilliard sits on the flat glacial till plain west of the Scioto River, with the river's Griggs Reservoir pool a few miles east of the city. That housing profile shapes our typical scope for rim joist & band joist foam in Hilliard. 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.

Rim-joist foam is the highest-ROI project across Franklin County's older housing, from Bexley and Clintonville's pre-war streetcar-suburb stock through Whitehall's postwar ranches, because almost none of it was built with rim-joist insulation. Two to three inches of closed-cell foam meets the Climate Zone 5A R-13 minimum and seals the band-joist leak, one that costs more over Columbus's longer heating season than it does farther south.

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 Hilliard routes through the local OH building department, and Climate Zone 5A R-value targets apply across the entire Columbus metro.
