Poultry barn spray foam insulation in Wetaskiwin is usually asked about for a building that is older than the standard it now has to meet, because the barns here were put up decades ago and the conditions expected inside them have been raised repeatedly since.
An older building held to a current specification
The barn has been re-equipped more than once. The ventilation is newer than the shell, the controls are newer than the ventilation, and the targets the operation is held to are newer again. What has not changed is the envelope, and it is now the limiting component. That shows up as equipment running at the edge of its capacity to hold conditions the building keeps giving away, which is expensive in a way that never appears as a single obvious fault.
Ventilation and envelope are one system, not two
A barn like this is deliberately ventilated at a controlled rate, and that rate only means anything if the air comes in where it was meant to. On an older shell with gaps at the eave, around fans and along the base of the walls, a share of the air arrives uncontrolled and lands wherever it lands. Sealing the shell is what gives the control system back its authority, and it is why the two are specified together on a Wetaskiwin barn rather than one at a time.
Where the moisture actually goes in one of these
The load inside is high and continuous, and it has to leave through the ventilation rather than through the building fabric. Where the envelope has cold surfaces it will not, it will condense on them instead: the underside of the roof, the top of the wall, the steel around a fan opening. That is a fabric problem and a bird health problem at the same time, and it is the single strongest argument for a continuous layer rather than an insulation held in place between framing.
Downtime is the constraint that sets the scope
The building is available between flocks and not otherwise, the window is short, and it is already committed to cleaning and preparation. Work that cannot be finished and cleared inside it is work that does not happen. That means scoping honestly against the window, staging across more than one turnaround where the scope is large, and being clear about what a shortened window buys, which is a conversation worth having before a date is agreed rather than during it.
Poultry Barn Spray Foam Insulation Wetaskiwin: Common Questions
Why does newer equipment not fix an older barn? That is the usual position here, and the envelope is what limits what the equipment can hold.
Why is our set ventilation rate not controlling the moisture? Only if the air enters where it should. Gaps in the shell take that control away.
When can the work be done? Between flocks, and the scope gets sized to that window rather than the other way round.
