Pole barns & shops
Closed-cell spray foam sprayed directly onto the steel is the most reliable way to stop a pole barn or shop roof from sweating and dripping, and it turns a cold building into one you can heat affordably. We insulate shops, garages, ag buildings and hobby barns across Isanti and the surrounding counties.
A steel roof over a heated or humid space will sweat. Snow melting off a truck, a propane heater, a concrete floor and even the ground under the slab all add moisture, and it condenses on the cold steel overhead, then drips on your equipment and rusts the fasteners.
Closed-cell foam sprayed directly on the underside of the steel keeps that warm, humid air from ever touching the cold panel. It is the most dependable condensation fix for metal buildings in a Minnesota winter.
How much foam a building needs depends on how you'll use it. An unheated machine shed may only need a thinner coat to control condensation. A heated shop you work in all winter needs more R-value on the roof and walls to keep heating costs reasonable. We match the thickness to your heating plans, not a one-size-fits-all number.
A little prep keeps spray day smooth:
Exposed spray foam is combustible. Depending on how the building is used and what your building official requires, foam may need to be covered with a thermal barrier like drywall or an approved protective coating. If you weld, grind or heat with a wood stove, plan on covering it. We'll walk through the options during the site visit.
FAQ
It depends on the building's size, the foam thickness you need for how the building is used, and access. We look at every building in person and give you a written estimate with the foam type, thickness and R-value spelled out.
Foam needs a clean, dry surface to bond to, so old blanket insulation or loose vapor barrier usually has to come out first. We'll look at what is there during the site visit and tell you exactly what needs to happen.
Yes. Closed-cell foam bonds to the steel and framing and stiffens the panels, which adds racking strength and reduces panel noise in wind and rain.
