Pole barn spray foam insulation in Peace River is applied to the inside face of the cladding, across the girts and the posts together. Post-frame is the standard farm building on the plateau above the valley, and what those buildings hold is the reason anybody looks at insulating them.
Grain and canola stored up on the plateau
The farming here is real and it is at the northern edge of where it is possible, which means storage matters more than it does further south. A crop that has come off in a narrow window and has to keep until it moves is sitting in a post-frame building through a very long winter. What damages it is not cold, it is moisture, and moisture in a stored crop comes from the crop itself, from the ground and from air moving through a building that was built to keep rain off rather than to hold a condition.
What the roof is carrying by February
These are light structures under a serious seasonal load. That is worth raising before any work is done, particularly on an older building or one that has been extended, because the conversation about what the roof is carrying belongs at the start rather than after somebody has changed the assembly. Foam itself is a light addition and adds very little, and the honest point is that the snow question should be settled independently of the insulation question.
The posts, the girts and the sheet as one surface
There is no cavity in a post-frame wall, so nothing can be fitted between anything. Batt hung across the inside face sags, leaves air behind it and stops working within a few seasons. Sprayed foam covers the posts, the girts and the cladding together as a single continuous surface with nothing behind it, which is the only arrangement that suits the way these buildings are built. It also means the timber posts stop being a thermal path of their own.
The bay with the workbench in it
Very few of these buildings justify treating in full, and the useful answer is usually a partition. One bay sealed, insulated and given a modest heat source becomes a workshop that is usable through a Peace River winter, while the rest of the building stays as covered storage. That is a fraction of the cost of the whole shell and it is what most owners actually want once the two options are priced side by side.
Pole Barn Spray Foam Insulation Peace River: Common Questions
What damages stored crop in these buildings? Moisture rather than cold, and a good deal of it comes in on air moving through the shell.
Can anything be fitted between the girts? No. There is no cavity, which is why the foam goes across the whole inside face.
Do we have to do the whole building? Usually not. Partitioning a working bay is a fraction of the cost and it is generally what people want.
