Garage spray foam insulation in Sundre goes onto the walls and the underside of the roof, sealing the building as it insulates it. Before any of that is worth quoting there is a decision to make about what the garage is for, and in this town there is also something going on outside the building that changes how it behaves at night.
Cold air collects in the valley bottom
Sundre lies in the Red Deer River valley with higher ground to the west. On a clear calm night, air cooled against the slopes is denser than the air around it and drains downhill, settling in the low ground. That is why the valley fogs and frosts heavily on still mornings, and it is why an unheated building down here can be measurably colder at dawn than one on a bench above town, with the same insulation.
For a garage that matters in a specific way. The coldest hours are the calm ones, which are also the hours when there is no wind to drive air through the building. The heat loss in those hours is radiative and conductive through the surfaces: the overhead door, the slab edge and the roof deck. Those are exactly the three things most garage insulation jobs do not touch.
The overhead door is the largest single surface
On a typical detached garage the door accounts for a substantial share of the wall area facing outside, and a plain steel sectional door has almost no thermal value and leaks around all four edges. There is no point spraying the three solid walls and leaving it. We cannot foam a sectional door, and we would not pretend otherwise. What belongs in the plan is an insulated door or a door kit, and new weather seals at the jambs, the header and the floor. The foam we apply to the surrounding walls then has something to be continuous with.
The slab edge is where the heat goes into the ground
A garage slab in this town is poured on free-draining gravel, which conducts well and stays cold. Heat in a warmed garage runs out through the perimeter of the slab, sideways to the outside air, and nothing you do to the walls above stops it. Where the slab edge is accessible we treat it, and where the building is being newly built we would put insulation under the slab perimeter before the pour. On an existing building the honest answer is that the slab edge is often the one item that cannot be properly fixed, and knowing that in advance is better than discovering it after.
Decide between heated and simply not freezing
These two aims lead to different quotes. A garage that must hold a working temperature while somebody is in it needs a sealed shell, real depth on the roof deck and walls, an insulated door and a heat source sized for the volume. A garage that only needs to stay above freezing so that paint, batteries and fluids survive needs much less, and a sealed shell with modest depth plus a very small heat input will often do it. Tell us which one you want and the quote will reflect it rather than splitting the difference.
The thermal barrier over the foam
Where a garage is attached to a house or is going to be finished, the sprayed foam has to be covered by an approved thermal barrier, normally drywall. That requirement sits in the plan from the start, because deciding later means paying for the same wall twice. The wall between a garage and a house also needs to be airtight for reasons that have nothing to do with comfort, and sprayed foam on that wall is the straightforward way to achieve it.

Garage Spray Foam Insulation Sundre: Common Questions
Why is the garage colder here than a friend's on the bench? Cold air drains into the valley bottom overnight. On still clear mornings the low ground is genuinely colder, and an unheated building follows the air around it.
Can you spray the overhead door? No. It needs an insulated door or a panel kit plus new seals. The walls around it are ours.
Do I need to heat it, or just seal it? Settle that first. Keeping a building above freezing is a far smaller job than keeping it comfortable, and they price very differently.
How much does garage spray foam insulation cost in Sundre? It follows the sprayed area and the depth each surface needs, plus the drywall if the foam has to be covered. The door and the seals are separate items and should be priced as such.
How do I choose a garage spray foam contractor in Sundre? Ask what their plan is for the door and the slab edge. A quote that covers only the three solid walls is quoting around the two biggest losses.
