Cold storage spray foam insulation in Edson is work on the coolers and freezers behind the businesses that feed the town: a grocery back room, a restaurant, a butcher, a supplier holding stock for camps and crews. Very few of these rooms were designed as cold storage. Most were built into something that already existed.
Coolers built into buildings that predate them
That is the fork here. A purpose-built cold room has a continuous envelope designed as one thing. A room framed into the corner of an older Edson building has whatever the building already had on two of its sides, and it inherits every gap and every uninsulated junction that came with it. The most common finding on these jobs is not a failed panel, it is a wall that was never a cold-room wall being asked to behave like one.
What is under the slab, and whether it was ever insulated
The floor is where these retrofits are decided. A freezer room built on an existing slab frequently has nothing under that slab at all, and the ground beneath a freezer that runs continuously will gradually freeze. In this climate the ground is already cold and wet, and freezing ground expands. That is how a floor lifts, how a door stops closing and how a room that worked for years becomes a problem. It is worth establishing what is under the slab before anything else is priced, because it changes the whole scope.
Frost heave under a freezer floor
It is worth naming plainly because owners rarely connect the symptom to the cause. A door that has started to bind, a floor with a crack that was not there, a panel joint that has opened at one end. Those are movement, and movement under a freezer in wet ground is usually frost. Insulating the floor assembly properly is what stops it, and where the floor cannot be lifted there are other answers, but none of them start by ignoring it.
Humid air outside is the load here
Everything about the vapour drive changes in a damp climate. Air that gets into the room brings a great deal more moisture with it than it would in a dry part of the province, and that moisture freezes on the evaporator, on the ceiling and on the product. More frost on the coil means more defrost cycles, and every defrost cycle puts heat into the room deliberately. Sealing the boundary properly is what reduces all of that, and it is worth more here than an equipment upgrade.
Cold Storage Spray Foam Insulation Edson: Common Questions
Why has the freezer door started to bind? That is movement, and under a freezer in wet ground it is usually frost heave. It is worth looking at the floor.
Why is there so much frost on our coil? Damp air getting in. Every gram of it ends up as frost, and every defrost cycle adds heat.
Is a retrofit worth it on an old building? Frequently yes, once you know which walls were never cold-room walls. That is the first thing to establish.
