People almost always ask what the inside will look like afterwards, and on an arch that is a fair question with a more complicated answer than on a flat wall. Quonset spray foam insulation in Okotoks frequently goes into a building somebody uses as a workshop or a garage, where the finish matters, and the covering over the foam is not optional anyway.
Foam needs a covering, and that is the starting point
Foam is combustible, so in any space that is used it needs a covering over it rather than being left exposed. That is not a decorating decision, it is a requirement, and it should be priced with the insulation instead of appearing afterwards as a surprise. What the covering has to be depends on how the building is used and is set by the authority that inspects it, which is a question we point at rather than answer.
The curve is what makes finishing awkward
Sheet material does not bend to an arch without effort. On a curved shell the practical options are a coating applied over the foam, which follows the shape exactly and adds no framing, or a lined interior built on light framing that stands the finish off the curve and eats some floor area. The first is usually simpler and cheaper on an arch. The second gives a flat wall to hang things on and a cavity for services, which is why people choose it in a workshop.
Decide the finish before the foam, not after
If a lined interior is going in, the framing wants to be planned before spraying so that anything bearing load reaches the steel rather than being fastened through insulation. A fastener driven through foam compresses it, breaks the air seal and makes a cold spot behind whatever it holds. This is the single most common regret on an arch job and it costs nothing to avoid.
What a coating does and does not do
It gives the required covering and a finished appearance in one step, and it follows the curve with no framing at all. It does not give you a flat surface, and it does not create anywhere to run wiring out of sight. If the plan is a proper workshop with benches, shelving and services, that argues for framing; if the plan is clean storage, a coating is usually the sensible answer.
Why the arch takes foam in the first place
No stud bays, no flat planes. Batt has nothing to sit in and rigid board cannot lie against the curve without leaving voids that condense unseen. Foam bonds to the shell and takes its shape, and it is the insulation and the air barrier together. It needs clean, dry steel with any active rust dealt with rather than covered.

Quonset Spray Foam Insulation Okotoks: Common Questions
Can the foam be left exposed? No. In a space that is used it needs a covering over it, which applies to an Okotoks workshop the same as anywhere else, and that gets priced with the insulation rather than raised later.
Coating or a lined interior? A coating follows the curve and needs no framing. A lined interior gives flat walls and a cavity for services but takes floor area. The use decides it.
What should be decided first? The finish. Anything that needs to reach the steel should be placed before spraying, because a fastener through foam breaks the seal and creates a cold spot.
How much does Quonset spray foam insulation cost in Okotoks? Foam needs a covering and that is the starting point rather than an afterthought, and the curve makes finishing awkward. Deciding the finish before the foam is what keeps the total honest.
