Pole barn spray foam insulation in Airdrie is nearly always the same conversation. Somebody bought an acreage outside town, it came with a large post-frame building, and they now want to use it for something the previous owner did not.
The shop that came with the property
These buildings are enormously useful and almost never set up for what the new owner has in mind. It was storage and they want a workshop; it was a workshop and they want to park vehicles in it heated; it held equipment and they want half of it finished. In every case the shell is the thing standing between the building and the plan, and it is usually completely untreated.
Why nothing you attach to it stays put
Post-frame construction has girts spanning between posts with the cladding screwed to them, and no cavity of the kind a house wall has. Anything fitted between the girts has to be held there, and over time it sags, falls or leaves voids for air to move through. That is why owners who have already tried batts in one of these buildings describe the result as having made very little difference. Foam adheres to what it is applied to and does not depend on anything holding it, which on an Airdrie acreage building is the difference between an assembly that lasts and one that has to be redone.
Decide the finish before the foam
If the building is going to be lined, the sequence matters and it is easy to get backwards. Wiring runs, mounting points and backing for anything heavy go in first, then the foam, then the lining. A fastener driven through cured foam breaks the seal and puts a cold point behind whatever it is holding, which on a building being fitted out over several years happens more than once.
Half now, half later
On an acreage budget this is a common request and it is worth being clear about. Treating half a building leaves a join between treated and untreated shell where condensation concentrates, which can be worse than leaving it alone. Doing the roof plane across the whole building and the walls later is a better split than doing one end completely, and it is usually a similar cost.
Pole Barn Spray Foam Insulation Airdrie: Common Questions
We put batts in and it barely helped. Why? There is no cavity holding them and no air barrier around them, so they sag and leave voids that air moves through. Foam adheres to the surface instead.
Can we do it in stages? Better across the whole building than half of it. A join between treated and untreated shell concentrates condensation, so the roof plane first and the walls later is the safer split.
We want to line the inside. What order? Wiring, mounting points and backing first, then foam, then lining. Fasteners driven through cured foam break the seal.
