Rim Joist & Band Joist Foam in Covington, KY

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 Covington 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.

Covington's residential core is 1850s-1920s row housing, single-family, and the historic MainStrasse district. Plaster walls, stone or early-brick foundations, and the dense urban grid character of the largest NKY river city. River-corridor and Licking-River-confluence proximity drives the moisture profile. That housing profile shapes our typical scope for rim joist & band joist foam in Covington. 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 Covington routes through the Kenton County KY building department, and Climate Zone 4A R-value targets apply across the entire Cincinnati metro including both sides of the river.
