Pole barns, shops and metal buildings
Pole barns, shops and metal buildings
A steel shell sweats, drips and swings with the weather. Closed cell foam on the roof and walls stops the dripping and holds the heat. Pole barns, shops, cabins and a round house so far.

Why steel buildings drip
Bare metal gets cold fast. When warm, damp air inside touches it, the water comes out of the air right on the steel and drips onto whatever is under it. Closed cell foam keeps that air off the metal. The foam has to be thick enough for the climate so its inside face stays warm, the same rule the DOE gives for foam on roofs: it must be thick enough to prevent dewpoint condensation on its interior surface
[1].
What we foam
- Pole barn and post frame walls and roofs
- Metal shops
- Cabins, sun rooms and round houses
- Under the slab on new builds, before the pour
Flood prone sites
FEMA rates closed cell and sprayed polyurethane foam Class 5, highly resistant to floodwater damage
[2]. If your building sits low, that matters.





Questions about this job
Why closed cell in a metal building?
It sticks to the metal, seals the seams, and is a vapor retarder at about 2 inches, so warm, damp inside air does not reach the cold steel and drip. The DOE rates closed cell under 1 perm at 2 inches [1].
Does it make the building stronger?
Closed cell does. The DOE says the racking strength of frame walls is substantially increased when closed cell foam fills the cavities, and roof structure and wind resistance are enhanced with closed cell on the roof deck [1].
Can you do just the roof?
Yes. We can price the roof and the walls separately so you can see both.
