Steel Gets Hot and Steel Sweats
Metal building and shop insulation is a common request around Shreveport, where shops, barns, garages and steel buildings dot the rural parts of Caddo, Bossier and DeSoto. A bare steel roof under a north Louisiana sun gets far hotter than the air, and with Shreveport averaging about 91 days a year at 90F or above, an uninsulated shop can be unusable on summer afternoons. In cooler months, humid air meeting cold steel overnight leaves condensation that drips on tools, vehicles and stored hay.
Why closed-cell foam
Closed-cell foam sticks directly to steel panels, insulates at about R-5 to R-7 per inch, and at typical thickness slows vapor so condensation does not form on the steel behind it. It also seals the seams, fastener holes and gaps at the eaves and base that let dust, wasps and wind in. Open cell is sometimes used where budget matters more and the space will be conditioned, with a vapor plan.
Other options
For some buildings, blown-in over a ceiling, or batts with a facing, can do the job for less. If the building has a finished ceiling or a loft, we look at whether foam everywhere makes sense or only on the walls and roof slopes.
Before spraying
We check for roof leaks and loose panels, since foam will hide them. Wiring, lights and anything mounted on the walls get masked or moved. Equipment and vehicles need to come out of the spray area.
Signs you need it
A shop too hot to work in after noon, water dripping from the roof on cool mornings, rust starting on the purlins, or a building you want to heat or cool. Get a free estimate

Metal Building & Shop Insulation Questions
Will spray foam stop condensation in a metal building?
Closed-cell foam at proper thickness keeps humid air off the cold steel, which is what causes the drip. It works best when the seams and eaves are sealed too.
How thick should foam be on a shop?
It depends on whether you will heat and cool the space. For drip control alone, a thinner coat can work; for a conditioned shop, more. We quote by thickness and R-value.
Can you foam a barn with animals or hay in it?
The building has to be cleared of animals, feed and equipment during spraying and while the foam cures.
Does foam add strength to a metal building?
Closed-cell foam can stiffen panels somewhat, but we sell it for insulation and condensation control, not as structural repair.
Can I air condition a shop after it is foamed?
Yes, that is one of the main reasons people foam a shop. Sealing the seams, eaves and base and adding foam to a planned thickness keeps a window unit or mini-split from fighting the sun all afternoon. Tell us how you plan to cool the building so we can size the thickness.
