Pole barn spray foam insulation in Blackfalds is applied to the inside face of the cladding, across the girts and the posts together. Around this town a large share of these buildings are new, because the acreages on the edge of a growing town keep getting bought and built on.
The acreage shop that went up last year
The common version here is not a farm building at all. It is a post-frame shop put up by somebody who bought an acreage, sized for vehicles and a workbench and whatever the household needs to store. It went up as a Blackfalds acreage package, and that package was structure, cladding, doors and concrete. What it almost never included was anything that makes the building usable through a winter, which is why so many of them are standing empty and cold a year later.
Nothing fits between the girts, and that decides the product
A post-frame wall has no cavity. There is nothing to fit a batt into, and anything hung across the inside face sags within a few seasons, leaves air moving behind it and stops doing much at all. Sprayed foam covers the posts, the girts and the cladding together as a single continuous surface with nothing behind it. It also covers the timber posts, which are a thermal path in their own right and which fitted materials leave entirely untreated.
Doing it before the building gets filled
This is the timing argument and on a new building it is unusually clear. An empty shop is the cheapest version of this job that will ever exist: every surface is reachable, there is no lighting or shelving to work around, nothing has to be moved and nothing has to come out. The same building two years later, with a bench down one side and a mezzanine at the end, costs materially more for exactly the same result.
Where a partition earns its place
Even on a new building the answer is frequently not to treat all of it. Sealing and insulating one bay properly, putting a modest heat source in it and leaving the rest as covered storage gives a workshop that is usable in January for a fraction of what the whole shell would cost. It is worth having both numbers in front of the owner, because the comparison usually decides the question without anybody needing to argue for either.
Pole Barn Spray Foam Insulation Blackfalds: Common Questions
Why is a brand new pole barn shop freezing? The package was structure, cladding, doors and concrete. The envelope was a separate decision nobody mentioned.
Can anything be fitted between the girts? No, there is no cavity. That is why the foam goes across the whole inside face.
Should we do the whole building? Usually not. Price a partitioned working bay alongside it and compare.
