Quonset spray foam insulation in Stony Plain is applied to the inside of a corrugated arch. The curve has no flat planes and no bays, so nothing can be fitted into it and only an adhered layer follows the shape without leaving a void behind itself. On these yards the arch is usually the middle generation of building: newer than the barn, older than the post-frame shed.
The middle building on a three-generation yard
That position explains most of what is wrong with it. The arch was the modern building when it went up, it took over from the barn, and it has since been superseded by something with a wider door and more height. So it holds whatever did not move to the new building and whatever came out of the old one, it has had the least attention of the three, and nobody has made a decision about it in twenty years. On a Stony Plain yard it is reliably the building with the largest gap between how much is stored in it and how much thought has gone into it.
What the yard would do without it
It is a useful question because it produces an honest number rather than a feeling. If the arch came down tomorrow, where would what is in it go. On a yard that already has a newer post-frame building with room in it, the answer is sometimes that most of the contents would simply move and nobody would miss the arch, which makes spending on its envelope hard to justify. On a yard where it is the only building with the span to hold what is in it, the answer is the opposite and the case is immediate. Asking it before pricing anything settles more than any amount of discussion about thickness.
The lean-to along one side, and where the envelope stops
Most arches of any age here have grown a lean-to down one flank, framed off the curve for the tractor, the wood or whatever needed to be under cover quickly. It is a sensible addition and it creates the awkward part of the job. The wall between the lean-to and the arch is now an internal line rather than an exterior one, the junction where the addition's roof meets the curve is the highest point warm air will reach, and the two structures were built decades apart with no thought of ever being one envelope. Deciding whether the lean-to is inside or outside the treated space, and then building that boundary properly, is the decision that has to be made before a price rather than during the work.
When the answer is to spend on the newer building instead
On a three-generation yard there is nearly always a choice, and it is worth putting plainly. Foam bonds to sound, clean, dry steel, and at the bottom of the curve on an arch of this age the steel is frequently neither: water stands there, equipment has knocked it over the years, and corrosion starts at exactly that line. Where it has gone past surface rust the money belongs in repair before insulation, and the repair on an arch is not cheap. At that point the honest comparison is not whether to fix the arch, it is whether the same money spent on the newer building on the yard would protect more of what matters. Frequently it would, and that gets said rather than quoted around.
Quonset Spray Foam Insulation Stony Plain: Common Questions
What is the first step when everything has ended up in the quonset? That is the normal case, and sorting what actually needs protecting is the first half of the job.
Can you price it from the dimensions? Not accurately. The sprayed area follows the curve and is well beyond the floor area.
Is it worth doing at all? Sometimes not, particularly where there is a newer building on the yard. That gets said plainly.
