Why Steel Buildings Sweat
Pole barn and shop insulation solves a problem every steel-building owner in the Fox Valley knows: condensation. Steel panels get as cold as the outside air. When you run a heater, or when warm, humid air drifts in on a spring day, that air hits the cold steel and condenses. The water drips on equipment, rusts fasteners and soaks anything stored below.
Closed-cell foam on the steel
Closed-cell spray foam bonds directly to the inside of the steel, so there is no air gap where condensation can form. It also adds rigidity and seals the seams and fastener holes. HomeGuide lists closed cell at $3.00 to $5.00 per square foot installed.
Sized to how you use it
A cold storage building that just needs to stop dripping can use a thinner layer. A heated workshop or a garage you work in all winter needs more. We ask how you use the building and plan the thickness around that.
Doors, coatings and rules
Large doors leak air, so we seal around frames. Depending on how the building is used, exposed foam may need a thermal or ignition barrier coating, and some towns have permit rules for heated outbuildings. We explain what applies to yours.
Outbuilding Work
Steel, wood and garage spaces.
Steel roofs and walls
Closed cell directly on panels.
Wood-framed shops
Foam or blown-in in walls and ceilings.
Heated garages
Walls, ceiling and the shared wall with the house.
Coatings
Barrier coatings where the use requires them.

Pole Barn & Shop Insulation Questions
How much does it cost to spray foam a pole barn?
Closed cell runs $3.00 to $5.00 per square foot installed by HomeGuide's figures. A building's total depends on wall and roof area and thickness; we measure and quote in writing.
Will foam stop my shop from dripping?
Yes, closed-cell foam sprayed on the steel stops the warm air from reaching the cold metal, which is what causes condensation.
Can you foam a building in winter?
The steel needs to be warm enough for foam to bond, so we may heat the building first or wait for a milder day.
Do I need a permit?
It depends on the town and how the building is used. Check with your local building office.
