Cold storage spray foam insulation in Wetaskiwin is more often about a room with a limit at both ends than a freezer, because the temperature-controlled spaces in this town are frequently paint, chemical and finish stores rather than food.
A room that must not get cold or hot is a harder problem than a freezer
A freezer has one target and everything is pushed in one direction. A finish store has a band: the product is unusable below one temperature and unstable above another, and the room has to sit between them through a year that runs from thirty below to thirty above. That is a two-directional problem, it is solved by the envelope far more than by equipment, and it is the specification most often given to a contractor as though it were an ordinary heated room.
Why these rooms end up inside a larger building
The store is nearly always a room built within a shop or a warehouse rather than a separate structure, which means most of its surfaces face conditioned or semi-conditioned space and one or two face the outside. Treating all six the same wastes money and treating them all as interior misses the ones that are not. Establishing which surface of a Wetaskiwin room faces what is a fifteen-minute exercise that changes the scope more than any other decision on the job.
The floor is the surface people forget
A room like this is built on the existing slab, and that slab runs continuously out under the rest of the building and down to ground that is frozen for months. The room is losing heat sideways through the concrete to everywhere else, and no amount of work on the walls addresses it. Where the room is being built rather than retrofitted this is cheap to solve and where it already exists it is the thing that explains a room which will not hold its band no matter what the equipment does.
A small room loses its whole volume every time somebody opens it
The other difference from a large chilled space is size. A store of a few square metres holds very little air, so a door opened twenty times in a shift exchanges the contents of the room completely, over and over, and the equipment spends its life recovering rather than holding. That is why the door detail, the seal around it and where the room sits relative to the traffic through the building matter out of proportion to their cost, and why a room put in the busiest corner rarely performs however well its walls are built.
Cold Storage Spray Foam Insulation Wetaskiwin: The Covering Requirement
Closed cell foam is used here because it resists moisture movement as well as heat, which matters in a room held at a different temperature from everything around it. In an occupied Wetaskiwin building that foam is covered by a thermal barrier, and in a store like this the covering is frequently also what makes the room cleanable, so it belongs in the specification from the start rather than being added later.

Cold Storage Spray Foam Insulation Wetaskiwin: Common Questions
What does a paint store need rather than a freezer? Then it has a limit at both ends, which is a harder envelope problem than a freezer is.
Do all the walls need the same treatment? No. Which surfaces face outside and which face the shop is what sets the specification.
Why will the room not hold temperature? Check the slab. It usually runs straight out under the rest of the building.
