Steel Buildings in Florida Heat
Metal building and pole barn insulation is common on the larger lots around Palm Bay, Malabar, Grant-Valkaria and Fellsmere, where steel workshops, garages, RV covers and barns are part of the property. Bare steel in Florida sun gets very hot, and on cooler mornings humid air condenses on the inside of the panels and drips. Closed-cell foam fixes both.
Why closed-cell
Closed-cell foam bonds to the steel, fills panel ribs and fastener gaps, and slows vapor so humid air cannot reach the metal. HomeGuide lists it at R-5 to R-7 per inch. It also dampens rain noise, which in a place that gets more than 50 inches of rain a year is a noticeable bonus. Open-cell foam lets vapor through and generally needs an interior liner in a steel building.
Storms
Hurricane Jeanne in 2004 brought a 74-knot peak wind to the Palm Bay co-op station. Foam does not replace proper fastening or bracing in a steel building, but sealing the gaps at eaves and ridges does keep wind-driven rain out better. Any loose or leaking fasteners should be fixed before foam goes on.
Matching the job to the use
A workshop you air condition needs roof, walls and end walls sealed and insulated. A storage barn may only need the roof done to stop drip and cut heat. An RV or boat cover with open sides may not need foam at all. We ask how you use the building and price accordingly.
Before spraying
We check for rust, leaking screws and old faced fiberglass, which usually comes down so foam can bond to the steel. Contents get moved or covered.
Permits
Insulating an existing building is usually straightforward, but converting a steel building to living space or a conditioned office can bring permit and code requirements. Check with the City of Palm Bay, your town or Brevard County first.

Metal Building & Pole Barn Insulation Questions
Will foam stop my metal building from sweating?
Yes. Closed-cell foam keeps humid air off the cold steel.
Can foam go over old fiberglass?
Usually the old faced fiberglass comes down so foam bonds to the steel.
Does foam help with rain noise?
Yes, closed-cell foam on the panels dampens it noticeably.
Do I need a permit?
Insulating usually does not change much, but converting to living space can. Check with your building office.
