There is no commercial poultry industry in the Bow Valley. What there is, out on the acreages along the valley and in the surrounding country, is small flock housing - a converted shed, a purpose-built coop, a corner partitioned off inside a larger building. Those are the buildings this page is about, and they behave very differently from the long commercial barns the term usually describes.
A small building fills with moisture quickly
This is the governing fact. Birds put out a surprising amount of water vapour relative to their size, through respiration and through their droppings, and in a small enclosure there is very little air volume to dilute it. A commercial barn has mechanical ventilation sized for the load. A backyard coop has a vent hole and hope. So the humidity inside a small flock building climbs far faster than the owner expects, and at mountain temperatures that humid air meets cold surfaces immediately.
Frost on the inside of the roof, then wet litter
The sequence is predictable. Moist air reaches the underside of a cold roof panel on a clear night and freezes there. On a sunny afternoon it melts and rains onto the litter. Wet litter then releases ammonia, ammonia at bird height causes respiratory problems and frostbitten combs are usually a humidity problem rather than a cold problem. Owners reach for a heat lamp, which adds no ventilation and raises the moisture-holding capacity of air that then condenses somewhere else. The heat lamp is the wrong tool and it is also a fire risk in a building full of dust and bedding.
Dry is the objective, not warm
Chickens handle cold considerably better than they handle damp. The specification that works at this elevation is a sealed, insulated shell with deliberate ventilation - an inlet low and an outlet high so moisture leaves continuously without a draught across the roosts. Closed-cell foam at about R-6 to R-7 per inch on the roof plane and the walls adheres to the surface, leaves no gap for air to reach cold steel or sheathing, and acts as the vapour control at roughly two inches. That removes the condensing surface. The ventilation then removes the water.
Bear country changes how feed is handled
This is a mountain valley with a serious wildlife presence, and feed is an attractant. Any insulation plan for a small flock building has to sit alongside secure feed storage, and if the feed room is being sealed and insulated as part of the work, it should be built to keep wildlife out as well as moisture. We mention it because it affects what the building is asked to do, and because a coop that is comfortable and unsecured is a problem rather than an improvement.
Covering the foam in a building with birds in it
Exposed foam needs an approved covering, and in a coop it needs one that can be cleaned and that birds cannot pick at. That is part of the specification and it belongs in the quote. So does a sensible approach to keeping the sprayed surfaces smooth enough to wash down, because a building that cannot be cleaned will not stay dry for long.

Poultry Barn Spray Foam Insulation Canmore: Common Questions
Does the coop need heating? No. Dry and ventilated beats warm every time, and a heat lamp in a dusty building is a fire risk as well as the wrong fix.
Why is there frost inside the roof? Moist air from the birds is reaching a cold surface and freezing on it. Insulating that surface removes the condensation point.
Will sealing it make the air worse? Only if you seal without ventilating. The plan is a sealed shell plus a deliberate low inlet and high outlet.
How much does poultry barn spray foam insulation cost in Canmore? Priced per board foot of sprayed area, so a small coop is a small number. The covering over the foam and the ventilation work should be in the same quote.
How do I get a poultry barn spray foam insulation quote in Canmore? Tell us the size of the building, the flock size and whether it is a purpose-built coop or a converted shed. Conversions usually need more preparation.
