Closed-cell spray foam stops the heat and the condensation that make a steel shell sweat and rust in humid West Tennessee — turning a shop or barn into conditioned space.
Tell us what the space is doing and we’ll come take a look — no charge, no pressure.
A metal building in humid West Tennessee has two problems no batt can solve: it conducts heat straight through the steel, and it sweats. If your shop, pole barn, or barndominium is an oven in summer and dripping condensation in the shoulder seasons, closed-cell spray foam is the standard fix — and it’s a big part of what we do around Jackson.
Steel is a superb conductor, so a metal roof and walls take on the outdoor temperature fast. When our warm, humid air touches that cooler metal, water condenses on the surface — the same way a cold drink sweats on a muggy day. In a climate as humid as ours, that condensation is relentless: it drips onto whatever’s below, rusts the structure, and ruins insulation that isn’t designed for it. The more humid the climate, the worse a bare or batt-insulated metal building sweats — and West Tennessee is plenty humid.
Closed-cell spray foam applied directly to the underside of the metal does two things at once. It insulates — at about R-7 per inch it slows the heat conducting through the steel — and because it’s a vapor and air barrier that adheres tightly to the surface, it keeps humid air from ever reaching the cold metal. No exposed cold surface means no condensation. That’s why closed-cell is the industry-standard treatment for metal buildings, and why batts, which leave gaps and don’t stop vapor, so often fail in them.
Pole barns and barndominiums especially benefit, because you’re asking a steel shell to perform like a home. Spray foam is what makes that realistic in a humid climate. New build or existing structure, we’ll assess it and tell you what it takes to seal it.
