Pole barn spray foam insulation in Stony Plain is sprayed across the inside of a post-frame building, over the posts, girts and cladding together. A post-frame wall has no cavity, so anything installed has to be held against the girts, where it sags and leaves voids and largely stops working once air moves behind it. On most Stony Plain yards this is the building that went up when the old one stopped being adequate.
The building that replaced the old one and inherited its job
The post-frame shed on a Parkland County yard is usually the second or third generation of storage on that property, built to hold what the settlement-era barn could no longer take: larger equipment, higher clearance, a wider door. It is therefore the building actually in daily use while the older structure gets the attention. That is worth pointing out, because the envelope money almost always belongs in this building rather than in the one people are more sentimental about.
The end walls are a different building from the sides
The long walls of a post-frame building are posts and girts, and the ends usually are not. They tend to be framed conventionally between the corner posts, they carry the large door, and they were built by whoever was closing the building in rather than by whoever erected the frame. That makes them a different assembly with different problems: a header over a wide opening with very little room for anything above it, a door track fixed through the wall, and a junction at each corner where two quite different constructions meet. They are also where most of the air is moving. On a building where only part of the work is affordable, the ends are frequently a better spend than another inch across the sides.
Dust from a century of use, and what it does to adhesion
On a building that has been in agricultural service for decades the inside face of the cladding carries a film of dust that nothing has ever cleaned off, and foam will not adhere reliably to it. Preparation on one of these is a real line item rather than a formality, and it is the one most often missing from a cheap quote. It is also the reason a job that looks identical to one done on a new building costs more: the surface has to be made ready before anything can be sprayed onto it.
Deciding how much of the building to bring inside
Very few of these need the whole volume treated. A bay for the work and the equipment that matters, with a proper sealed partition and the rest left as covered storage, is a fraction of the cost and produces a space that comes up to temperature quickly. The condition is that the partition becomes an exterior wall the moment it is built, so it is sealed to the underside of the roof rather than stopping at a convenient height, and it is detailed as an envelope surface rather than a divider.
Pole Barn Spray Foam Insulation Stony Plain: Common Questions
Why did batt insulation do nothing in our post-frame wall? That is what a post-frame wall does to batt. There is no cavity for it to work in.
Why is preparation a separate line? Decades of dust on the inside of the cladding. Foam will not bond to it and it has to come off.
Do we need the whole building done? Usually not. One bay properly partitioned is the common and much cheaper answer.
