Storage demand in a commuter town comes from two places: households in newer houses that have less storage than they expected, and small trades businesses that need a secure place for tools and material close to where they live. Both of those customers will pay more for a unit that does not swing with the weather, which makes this an envelope decision with a revenue answer rather than a comfort one.
Two building types on most sites, and only one of them is a single job
A drive-up row is a series of units each with its own roll-up door to the outside. Every unit is its own little building, the door is the biggest part of its envelope, and there is no practical way to make one unit stable without treating the whole row.
A corridor building is different. One external shell, one entrance, an internal hallway, and units partitioned off either side with demising walls that frequently stop short of the deck. Because the partitions do not reach the roof, the whole interior is effectively one volume, which means one sprayed shell conditions every unit in the building at once.
That distinction is the first thing to establish, because it decides whether you are quoting a building or a row of boxes.
Temperature is not the product. Stability is
An operator does not need to hold a comfortable temperature. What a tenant needs is for the contents not to cross the dew point, because that is the event that ruins things: paper, photographs, upholstery, documents, tools, anything with a finish on it. Condensation happens when a surface in the unit is colder than the air touching it, and in an uninsulated steel building the coldest surface by a wide margin is the underside of the roof deck.
Spray the deck and the roof stops being the cold surface. The interior then follows the daily average rather than the hourly extreme, the swing that drives condensation disappears, and in an unheated building that is most of the result for a fraction of the cost of heating one.
Which is why unheated is the easier job, not the harder one
There is no heating plant to size, no fuel to buy, and no combustion air to arrange. The objective is simply to slow the building down, and a continuous adhered layer on the deck and the upper walls does exactly that. Closed-cell is the material because it bonds to steel, does not absorb water, and is its own vapour barrier at around two inches, so no separate membrane has to be lapped in a building full of partitions.
If you do decide to heat a corridor building, the same sprayed shell is what makes that affordable, and it turns a standard unit into a premium one.
Where to start on an existing site
The corridor building's roof deck first, then the top of its exterior walls down to the height where the racking or the units block access. Then the drive-up rows, taking the roof plane as one continuous run over all the units rather than unit by unit, because the partitions between them are not sealed and treating one in isolation achieves nothing.
Doors last, and usually by replacement and weatherstripping rather than by spraying.
Working on an occupied site
Tenants have keys and they come in the evenings and at weekends, which is exactly when the work is quietest for everybody else. The job gets zoned, a run is closed off at a time, re-entry intervals are posted, and the tenants in that run get told before the day rather than on it. On a site where people hold their own keys that notice is not a courtesy, it is how the schedule holds.

Self Storage Spray Foam Insulation Coaldale: Common Questions
Do we have to heat the units? No. Stopping the swing is what protects the contents, and that is a deck and shell job. Heating is a product decision on top of it.
Why spray the roof rather than the walls? Because the deck is the coldest surface in the building and it is the one condensation forms on. The upper walls come next; the lower walls matter least.
The partitions do not reach the ceiling. Is that a problem? For insulating, it is an advantage: the building is one volume, so one sprayed shell serves every unit in it.
How much does self storage spray foam insulation cost in Coaldale? It is priced per board foot over the sprayed area, so deck and wall area times thickness sets it, and any required thermal barrier over the foam is separate. A roof-only scope is a much smaller number than a full shell and it delivers most of the stability.
How do I choose a self storage spray foam contractor in Coaldale? Ask whether they are quoting the building or the units, and how they intend to notify tenants and manage re-entry. On an occupied site the second answer is the one that decides whether the job runs.
