Lethbridge warehousing serves an agri-food region, and that changes what the envelope is being asked to do. Warehouse spray foam insulation in Lethbridge is often a temperature-control requirement rather than a comfort one.
Product-driven, not comfort-driven
In a general distribution warehouse the envelope is about operating cost. In a food or agricultural warehouse it is often about the product, and the tolerance is narrower.
Two things follow.
Temperature stability matters more than temperature. A building that swings is harder on stored produce than one that sits slightly warmer but steady. Stability comes from a continuous envelope and a large thermal buffer, not from a bigger heater.
Humidity is part of the specification. Produce respires and gives off moisture. Washing and handling add more. That moisture has to be managed rather than allowed to migrate to the roof deck, condense on cold steel, and fall back onto the stack.
If your building holds anything perishable, say so when you enquire. It changes the specification, not just the quantity.
Where the money actually goes
The roof deck, not the walls. In a warehouse footprint the roof is the dominant surface and sits at the top of the pressure gradient. Heat rises to it and leaves through it.
Stratification. Heating a tall space to be comfortable at floor level means the upper volume runs much hotter, and that hot layer sits against the deck. You are paying to heat air nobody uses.
Door cycling, which insulation cannot fix. The achievable goal is fast recovery between cycles - and sealing is what delivers that, because you stop reheating air that immediately leaks away.
Wind changes the door maths
This is the Lethbridge difference. In a sheltered location a dock or overhead door loses a defined volume per cycle and then the building settles. Under steady wind the losses continue after the door closes, because pressure keeps driving air through the gaps around the opening.
So the door perimeter seal matters more here than almost anywhere in the province, and it is the detail most often left out of a quote. Ask about it directly.
Water off the steel onto the stock
Warm moist air rising to cold steel condenses and falls on whatever is below. In a warehouse holding cardboard, packaging or produce that is damaged product, and it is routinely chased as a roof leak for years.
A continuous adhered air and vapour seal against the deck stops interior air reaching the steel at all. See stopping condensation in a metal building and insulating a warehouse cost-effectively.

Warehouse Spray Foam Insulation Lethbridge: Common Questions
Why does agri-food storage change the spec? Because temperature control is the product rather than a comfort feature, so the envelope is scoped to a duty cycle rather than to an R-value.
Does the wind affect a building that size? In Lethbridge it affects the large surfaces most - a big roof deck and long walls give wind a lot to work on, which is why continuity of the seal matters.
Is condensation a risk in a cooled building? It moves to a different surface but does not go away. That is why cold storage is specified differently from a dry warehouse.
How much does warehouse spray foam insulation cost in Lethbridge? This is product-driven rather than comfort-driven, so the target comes off the label rather than off a thermostat. Wind changes the door arithmetic here more than it changes the wall arithmetic.
