Pole Barn & Garage Insulation That Holds Heat
Pole barn and garage insulation turns a cold steel building into a space you can heat. Across Saginaw County's farms and acreages, pole barns and detached garages are used as shops, storage and hobby space, and most were built with bare steel or a thin blanket. Heating one without insulation burns fuel, and warm, moist air meeting cold steel drips water onto everything inside.
Closed-cell foam on steel
Sprayed directly on the steel or onto the inside of the panels, closed-cell foam bonds to the metal, insulates it and blocks moist air from reaching it. That stops condensation and drip. One to two inches handles condensation on many buildings; a building heated all winter usually gets more.
Wood-framed garages
Detached garages with wood framing can be sprayed between the studs and rafters, or the walls can be foamed and the ceiling blown with loose fill if there is an attic.
Barriers and codes
Some uses need an ignition or thermal barrier over the foam. A garage or shop with living space nearby may also need to meet code. We tell you what applies and price it.
Cold-weather scheduling
Spray foam needs workable surface temperatures, so unheated buildings are warmed before spraying or scheduled for milder days.

Pole Barn & Garage Insulation Questions
How thick should foam be in a pole barn?
One to two inches stops condensation on many buildings; heated shops usually get more. We match it to your use.
Can you spray in winter?
Yes, if the building and surfaces are warmed enough for the foam to cure properly.
Do I have to empty the barn?
Large items can stay if moved away from the walls and covered.
Can you insulate just the roof?
Yes. The roof is where most heat escapes and most drip happens.
