Machine shed spray foam insulation in Wainwright is bought for the machinery, not for comfort. Nobody spends the winter in a machine shed. What they want is for the combine, the air seeder and the sprayer to come out in spring in the condition they went in, and for the shed to stop raining on them in the meantime.
Why an unheated shed still gets wet
The question we get asked most is how a building with no heat in it can have a condensation problem. The moisture does not need a furnace. It comes in on equipment that was working in a damp field, off a gravel or dirt floor, off anything stored in the building, and in on every exchange of outdoor air. The steel does not have to be cold in absolute terms, only colder than the dew point of the air touching it. On a clear prairie night a steel roof radiates heat straight to the sky and drops below the air temperature, which gets it there easily.
What that does to the equipment
Water condenses on the underside of the roof deck and drips, and it also condenses directly on the cold steel of the machines themselves. That is the version that costs money. It sits in bearings, on hydraulic fittings, on chains, on the connectors and boards in the electronics that modern equipment is full of, and it does it repeatedly through a long unbroken cold season with no thaw to dry anything between events. The corrosion that shows up in spring was not a leak; it was months of condensation.
Removing the cold surface, not the air
The usual attempts are a vent, a fan, or a liner hung off the purlins. A fan moves air and leaves the steel exactly as cold as it was. A liner creates a void between itself and the cladding where the condensation now happens out of sight, which converts a visible problem into a hidden one. Closed-cell foam applied directly to the inside face of the cladding adheres to it, leaves no void, and raises the surface temperature of the inside face above the dew point. The cold surface stops existing.
A shed needs less depth than a shop
This is where machine sheds get over-specified. A heated shop needs enough R-value to hold a working temperature economically. An unheated machine shed needs enough to keep the inside face above the dew point and to slow the night-sky cooling, and that is a shallower application. We will quote what the building is for rather than the deepest number the sprayer can lay down, and on a yard with several buildings that difference frees up budget for the one that actually needs it.
Doors, eaves and driven snow
Machine sheds have very large openings, and around Wainwright the thing that finds them is dry wind-driven snow, which follows the air path rather than piling against the wall. Snow inside a shed, on equipment, is both a nuisance and a signal: it marks where the air is moving. Sealing the eave line and the door headers deals with both at once, and it is usually a small part of the overall job.

Machine Shed Spray Foam Insulation Wainwright: Common Questions
How can there be condensation with no heat in the building? The moisture comes from the equipment, the ground and the outdoor air, and a steel roof radiating to a clear sky gets colder than the air around it. That is all it takes.
Is it the roof leaking? Check the pattern. A leak follows the weather and shows up at a seam or a fastener; condensation appears on clear cold nights and forms across the whole surface, including on the machinery itself.
Would a fan or more vents be enough? They move air without warming the steel. The cold surface is the cause, so it is the thing that has to change.
How much does machine shed spray foam insulation cost in Wainwright? Priced by sprayed area and depth, and an unheated shed needs less depth than a heated shop of the same size. Clearing the equipment out so the walls and roof are reachable is the owner's biggest input.
How do I choose a machine shed spray foam contractor in Wainwright? Ask what depth they are quoting and whether it is for keeping the building warm or for stopping the sweating. If they cannot tell the two apart you are being sold a shop specification for a storage building.
