Quonset spray foam insulation in Morinville nearly always arrives as the same question: there is a quonset on the yard, somebody wants a heated shop, and the building is already standing. That is a reasonable starting point and it deserves a straight answer rather than a quote.
Already standing is not the same as suitable
The appeal is obvious and the arithmetic is worth doing anyway. A quonset gives an enormous volume for its floor area, because the roof is the wall and it carries on up and over. Heating a workshop means heating that whole volume, and the useful part of it is the two metres above the floor. Before anything is sprayed, the comparison worth making on a Morinville yard is the cost of conditioning this building against the cost of a smaller purpose-built one, because the answer is not always the one people expect.
There is no flat wall to work against
The practical objection is one nobody raises until the shop is finished. The curve starts at the floor, so there is no vertical surface to stand a bench against, hang a cabinet on or fix a rack to without building a frame inside first. That frame is a real cost and it usually gets discovered after the insulation is priced. It also changes the insulation, because a stud wall built inside the arch creates a cavity between two surfaces that has to be dealt with rather than ignored.
Where it does make sense
Cold and dry storage, machinery under cover, and any use where the volume above is irrelevant because nobody is trying to heat it. In those cases sealing the arch is straightforward and it delivers exactly what it should, because a continuous layer suits a curved surface better than anything fitted in pieces does. That is the use these buildings are good at, and a Morinville owner who wants secure dry cover rather than a warm room is asking the right question of the right building.
If it is going to be a shop anyway
Then two things carry the job. The floor, because most of these are on gravel or on a slab poured later, and a heated building over open ground will not stay dry. And the end walls, which are a separate structure from the arch and where the largest air paths are, running full height on both sides. Doing the arch and leaving those is the version of this job that disappoints, and it is the version most often priced.
Quonset Spray Foam Insulation Morinville: Common Questions
Is using the quonset we already have cheaper than building new? Not always. The volume above the working height is what you would be heating.
Can we put benches along the wall? Not without framing inside first, because the curve starts at the floor. That is a real cost.
What is it genuinely good for? Cold dry cover. Sealing it for that is straightforward and it does what it should.
