The measure that matters for a Lethbridge shop is not how warm it gets. It is how fast it recovers after the door closes. Shop spray foam insulation in Lethbridge is judged on how fast the building recovers, not on its peak temperature.
Why recovery is the right target
A shop door is enormous, and every cycle replaces the air in the building. That is unavoidable - you cannot insulate your way out of an opening that size.
What wind adds is that the losses continue after the door shuts. Steady pressure keeps pushing air through the gaps around the door track, at the eaves, through service penetrations and along the sill. A building that would coast for an hour in still conditions gives it up considerably faster with wind on it.
So the useful question when pricing work is not "what R-value" but "how quickly does this building come back to working temperature, and how long does it hold?" Sealing is what moves that number. Depth alone does not, because the air is going around the insulation rather than through it.
The door perimeter is usually the biggest single gap
It is also the one most often left out of a quote. Ask about it directly - the seal around and above the door track, and the condition of the weather seal at the floor. On many shops that single detail is worth more than adding depth anywhere else.
Agricultural and food-processing yards
Lethbridge sits at the centre of an irrigated agri-food region, and a lot of shops here serve that: equipment maintenance, produce handling, transport.
Two things follow. Buildings that see washing or wet processing carry a much heavier moisture load against the envelope than a dry workshop, and vapour control has to be deliberate rather than incidental. And buildings that hold anything temperature-sensitive depend on the continuity of the assembly far more than on headline R-value - a gap is where control is lost and where condensation forms.
Say what happens inside the building when you enquire. It changes the specification, not just the quantity.
Condensation and equipment
Warm moist air reaching a cold steel deck condenses and drips onto whatever is below. In a shop full of tools, machinery and vehicles that is corrosion - slow, continuous, and expensive over years.
A continuous adhered air and vapour seal against the deck prevents interior air reaching the cold metal at all. See stopping condensation in a metal building and preventing rust.

Foam in a shop needs an appropriate thermal barrier over it. Get it into the quote rather than discovering it at inspection. See thermal barrier vs ignition barrier.

Shop Spray Foam Insulation Lethbridge: Common Questions
What should I be measuring in a Lethbridge shop? Not how warm it gets, but how fast it recovers. In a wind corridor a leaky shop bleeds heat continuously, so the seal is what you are buying.
Does wind get in around the door? The header and surround are usually the worst path, and they are sealed as part of the job rather than treated separately.
Is condensation an issue on tools? In an intermittently heated shop, yes - the temperature swings put moisture onto metal overnight, and stopping that is often the reason for the call.
How much does shop spray foam insulation cost in Lethbridge? The door perimeter is usually the biggest single gap in a shop, so a quote that prices walls and roof but not the doors has missed the largest item. Recovery of usable heat is the target rather than a rating on paper, and that is what the specification should be aimed at.
