Pole barn spray foam insulation in Wetaskiwin is mostly work on buildings put up in the nineteen seventies and eighties as open-sided shelters, which have been walled in at some point since by whoever owned the place, and the way they were closed in decides the whole job.
A building that was closed in by its owner, not its builder
The original structure was posts, trusses and a roof, open on one or two sides. The walls came later, built by the farm, from whatever was available, and they were built to keep weather out rather than to be part of an envelope. That produces walls that stop short at the top, walls sitting on grade with no proper base, and a sheet fixed to the outside of the posts on one elevation and the inside on another. All of that is workable and none of it is what a drawing would show.
The posts go into the ground and the ground is cold
On a pole building the structure continues below grade, so every post is a direct path from the inside of the building to frozen soil. Where the wall meets the ground between those posts there is frequently nothing but a board and a gap. That perimeter line is the first thing worth treating in one of these, it is reachable without touching the rest of the building, and on a Wetaskiwin building it usually costs less than any other item on the list.
The roof was never sheeted for what happens under it now
An open shelter did not need a ceiling and most of these have the underside of the roof steel exposed to the space. Warm moist air off machinery, animals or a heater rises to that steel and condenses on it, and it drips back down on whatever is stored below. Owners describe it as a leaking roof and it almost never is. A continuous layer against the underside is what stops it, and it stops it because there is no longer a cold surface for the moisture to find.
Deciding how much of it needs to be warm
These buildings are large and the heated requirement is usually small: a bench, a work area, a place to thaw something out. Building a sealed room inside the shell and treating the rest as covered storage is what most Wetaskiwin owners actually want once the two options are priced side by side, and it is worth putting both numbers on paper rather than assuming the whole building is the scope.
Pole Barn Spray Foam Insulation Wetaskiwin: Common Questions
Does it change the job if the walls were added later? That is the normal case here, and how they were added changes the scope more than their material.
Is a dripping steel roof a leak or condensation? That is condensation on the underside of the steel rather than a leak.
Do we heat the whole thing? Rarely worth it. A sealed room inside a large shell is usually the better answer.
