Why Steel Buildings Sweat
Metal building and shop insulation solves two problems at once on the coast. Bare steel turns into a radiator in summer, so the inside of a shop can be hotter than outdoors by mid-afternoon. And when humid air touches steel that has cooled overnight or after a storm, water condenses on the panels and drips on tools, vehicles and stored goods. Closed-cell spray foam sticks directly to the steel, insulates it and keeps humid air from reaching the cold surface.
Where we see them
Inland from the beach, around Lyman, Saucier, Kiln and north toward Wiggins, larger lots mean more metal shops, garages, carports with enclosed bays, barns and storage buildings. Businesses in Gulfport's industrial areas run metal warehouses and work bays too.
What we spray
Closed-cell foam goes on the underside of the roof panels and on the wall panels, usually one to two inches or more depending on how much heat control you want. Foam also locks down loose seams and fills gaps at the eaves, which keeps wasps and dust out. An optional coating can go over exposed foam where code or appearance calls for it.
Before you build
If the building is not up yet, ask us before you order. Knowing the panel profile and framing helps us price it, and it may change what you order for vapor control.

Metal Building & Shop Insulation Questions
How thick should foam be on a metal shop?
One inch of closed-cell foam usually stops condensation; two inches or more gives better heat control if you plan to cool the space. We price the options.
Can you foam a building that is full of stuff?
Yes, but contents need to be moved away from the walls or covered. We can talk through what needs to move before the job.
Does foam on the roof panels cause leaks to hide?
It can make small leaks harder to spot, so we check the roof for leaks and loose fasteners first.
Is open-cell foam OK for metal buildings?
Closed cell is the usual choice because it slows vapor and handles moisture better. Open cell can make sense on the roof of a building that will be fully conditioned.
Do I need a permit to insulate a shop?
Rules vary by city and county and by how the building is used. Check with Gulfport, Harrison County or your local building office before major work; we can give you the details they may ask for.
