Pole barn spray foam insulation in Didsbury is applied across the inside face of a post-frame building, over the posts, the girts and the sheet together, because a post-frame wall has no cavity for anything to sit in. A good share of the buildings around this town went up as kits erected by the people who own them.
A kit put up by the people who own it
That is not a criticism and these buildings stand for decades, but it does change what gets checked first. On an owner-erected shell the things that vary are the squareness of the frame, how tightly the sheeting laps were pulled up, and whether the closures at the eave and the base went in at all. Each of those is a route for air and driven snow, and each is easier to see from inside before anything is sprayed than after. Where the closures were skipped, they get dealt with as part of the preparation rather than being buried, because foam over a gap that is still moving air is money spent on the wrong problem.
The building that has been nearly finished for years
The common Didsbury version of this is a shop that was put up with the intention of finishing it properly later, and later has not arrived. There is often a partition halfway across, a bay lined in something, and three walls of bare steel. That history matters because it decides how much of the existing work is worth keeping. Sheeting that was screwed to the girts can usually stay and be sprayed behind or built to; a stud wall standing off the frame with batt in it is generally worth taking out, because it makes the assembly impossible to seal and hides whatever is happening on the steel behind it.
Why a post-frame building is quoted by the shell and not by the floor
People ask for a price on a forty by sixty and expect the arithmetic to run off that number. It does not. What gets sprayed is the surface area of the walls and the roof plane, plus the faces of every post and girt standing proud of them, and on a tall building that total is a long way from the floor area. This is the single most common reason two quotes on the same building differ by more than they should. A quote worth comparing states the surfaces being covered and the thickness on each, and anyone quoting from a floor dimension over the phone is guessing.
Working in a building that is full of the year's equipment
Most of these cannot be emptied, and around Didsbury the contents are usually the machinery the operation runs on. The practical answer is to work it in sections, with one bay cleared at a time and the rest sheeted off, which is slower than an empty building and entirely normal. What has to be agreed first is where things go while their bay is being done, because that is the part that stalls a job on the day. Cure and ventilation are planned into the same conversation, since nothing goes back in until the foam is properly off-gassed rather than merely hard to the touch.
Pole Barn Spray Foam Insulation Didsbury: Common Questions
Why can nothing be fitted between the girts? There is no cavity in a post-frame wall. The layer has to be sprayed across the frame itself.
Can you price it off the building dimensions? No. It is priced on the surfaces sprayed, which on a tall building is well beyond the floor area.
Can spray foam be installed while the shop is full? That is the normal case. It gets worked a bay at a time with the rest sheeted off.
