Stop the Drip, Keep the Heat
Pole barn and garage insulation is a different job from insulating a house. A steel building has no cavities to fill, the metal goes cold fast, and any warm, damp air that touches it condenses and drips. That happens in shops, machine sheds and detached garages all over the farm country around Davenport, Eldridge, DeWitt and Geneseo, and in plenty of town garages too.
Why closed-cell foam on steel
Closed-cell spray foam sticks directly to metal, insulates at R-5 to R-7 per inch according to HomeGuide, and seals the seams and fastener holes where air sneaks in. Because it keeps warm air off the cold steel, it stops the condensation that rusts fasteners and drips on equipment. One layer does three jobs: insulation, air seal and condensation control.
How thick
It depends on what you use the building for. A cold storage shed may only need enough foam to stop condensation. A heated shop that you use through a Quad Cities winter needs more. We ask how you plan to heat it and to what temperature, then size the thickness and write it on the quote. HomeGuide's closed-cell range is $3.00 to $5.00 per square foot installed.
Wood-framed garages
An attached or detached garage with stud walls and a truss ceiling can be done with spray foam, blown-in or a mix. If there is a room above the garage, the ceiling and the shared wall with the house are the most important parts to seal, both for comfort and to keep exhaust out of the house. Open-cell foam is often enough in a garage that is not heated.
Code and permits
Agricultural buildings are often treated differently from homes under building codes, but a heated shop, a garage with living space above or a building that is partly commercial may not be. Check with your city or county before work starts. We can tell you what we will install so you can answer their questions.
Getting ready
Foam needs to go on clean, dry steel within a working temperature range. In winter, an unheated building may need temporary heat before we spray. We mask doors, windows and anything you do not want foam on. Get a free estimate

Pole Barn & Garage Insulation Questions
Will spray foam stop my pole barn from sweating?
Yes, closed-cell foam on the steel keeps warm, moist air from touching the cold metal, which is what causes the drip.
Can foam go on bare metal?
Closed-cell foam bonds to clean, dry steel. We check for oil, rust and moisture first.
Do I need a permit to insulate a pole barn?
Rules vary by city and county, and heated or partly residential buildings may be treated differently from farm storage. Check with your local building office.
Can I insulate a garage that is not heated?
Yes. Many people insulate to keep the garage warmer or to protect the room above. Open-cell or blown-in can be enough.
