Pole barn spray foam insulation in Lacombe is applied to the inside face of the cladding, across the girts and the posts together. On most yards around here the post-frame building is the newer one, put up when the original barn stopped being usable, and it is doing the work now.
The building that replaced the old barn
These went up because they are quick, cheap per square foot and they suit machinery. What they were not designed for is holding a condition. The specification that got them built was rain off the equipment and a door big enough, and the envelope was whatever came with the package. Years later the same building is being asked to store product, house a workshop or shelter animals, and the gap between those two briefs is the whole subject here.
Nothing sits between the girts, which 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 behind it and stops working. Sprayed foam covers the posts, the girts and the cladding as a single continuous surface with nothing behind it. It also covers the timber posts, which are a thermal path of their own that fitted materials leave completely untreated.
What one of these holds through a central Alberta winter
Look at the contents and the requirement becomes clear. Equipment that must not condense, product that must stay dry, sometimes animals, sometimes a workbench somebody uses on a Saturday. Those want different things, and the mistake is treating the whole shell to suit the most demanding of them. It is worth listing what is actually in the building before anybody prices anything, because the answer frequently is that most of it does not need the whole treatment.
Where a partition pays for itself
On a long post-frame building the arrangement that works is almost always to seal and insulate one bay properly, put a modest heat source in it, and leave the rest as covered storage. That gives a workshop usable in January for a fraction of the cost of the whole shell, and it avoids paying to warm a volume nobody stands in. It is worth pricing both ways so the comparison is in front of the owner rather than assumed on their behalf. On a long Lacombe shed the difference between the two numbers is usually large enough to decide the question on its own.
Pole Barn Spray Foam Insulation Lacombe: Common Questions
Can anything be fitted between the girts? No, there is no cavity. That is why the foam goes across the whole inside face.
Do we have to treat the whole building? Usually not, and usually you should not. Partitioning a working bay is the better spend.
Does it cover the posts too? Yes, and that matters. The posts are a thermal path that fitted materials leave untouched.
