Poultry barn spray foam insulation in Didsbury is work on production buildings where the envelope is one input among several and the operator generally understands the others far better than any contractor does.
Staying inside what an envelope contractor actually knows
This is the right starting position on a building like this. The operator manages stocking, feed, lighting and ventilation and has been doing it for years. What an insulation contractor brings is narrower: a shell that holds a stable temperature and does not let water form on its inside surfaces. Around Didsbury the useful conversation is about that boundary, and a contractor who starts advising on flock management has walked out of the part they know.
Why a sealed shell makes a small ventilation rate possible
Birds put a great deal of moisture into the air continuously. It has to be removed, and it is removed by deliberately exchanging air, which costs heat. In a leaky building that exchange competes with air arriving uncontrolled through every gap, so the rate has to be run higher than the flock needs and the heat goes with it. Sealing the shell is what lets the ventilation be turned down to what is actually required, which is the whole of the contribution this work makes.
The inside surfaces are the ones that decide it
Condensation in one of these forms on the coldest interior surface, which is normally the underside of the roof and the top of the walls, and what it lands on is the litter. Wet litter is a problem in its own right and it feeds straight back into the humidity in the air. Insulating and sealing those surfaces from the inside removes the cold plane that the water was forming on, and that is a measurable change rather than a comfort improvement.
What washing down means for the specification
These buildings get cleaned hard between flocks, and that has to be accounted for at the start. The finish over the foam has to tolerate being washed and has to be continuous enough not to trap water behind it. Where the foam is left accessible in a Didsbury barn it carries a thermal barrier or the ignition barrier the space calls for, and on a building that is washed down that covering is a practical requirement as much as a code one.

Poultry Barn Spray Foam Insulation Didsbury: Common Questions
Will this let us ventilate less? It lets the rate be set to what the flock needs rather than fighting uncontrolled leakage.
Where does the condensation form? On the coldest inside surfaces, usually the roof underside, and it lands on the litter.
What goes over spray foam in a barn that gets washed down? Then the covering over the foam has to tolerate that, and it is specified from the start.
