Pole barn spray foam insulation in Fort McMurray is usually about making a large, cheaply enclosed volume usable in conditions that punish every shortcut in how it was built.
Heating a large volume at severe temperatures
Post-frame construction gives a lot of enclosed space for the money, and that is exactly the problem once somebody wants it warm. The volume is large, the shell is thin, and at the temperatures this city sees the heat leaves as fast as it is produced. Owners respond by adding capacity, which raises the fuel bill without making the building usable. The envelope is what changes the arithmetic, and until it is addressed no heater is the right size.
What the ground does under a post
Posts are set into ground that freezes deep and stays frozen for months around Fort McMurray, and in some locations the ground is soft and holds water. That affects the detail where the wall meets grade in two ways: it is a heat path, and it is where ground moisture arrives into the base of the wall. It is the most commonly skipped detail on these buildings and worth naming explicitly in any scope.
Condensation in a building that is warmed intermittently
Very few of these buildings are held at temperature. They are warmed when needed and left the rest of the time, and every warm-up drives moisture into a cold shell. In a post-frame building with no continuous air barrier, that moisture reaches the cladding and freezes on it, then thaws and runs when the building is next used. The pattern is misread as a leaking roof more often than not.
Deciding what the building is actually for
The scope divides cleanly. A building kept above freezing to protect what is in it is one specification. A building somebody works in for a shift is another, and it needs the walls, the door surrounds and a decision about the floor. Establishing which one is wanted before pricing avoids both overspending and disappointment, and on a Fort McMurray building the gap between the two is wider than it would be in a milder market.
Pole Barn Spray Foam Insulation Fort McMurray: Common Questions
We added a bigger heater and it made little difference. Why? Because the heat is leaving as fast as it arrives. Until the shell is addressed, no heater is the right size for the building.
What about where the posts meet the ground? It is both a heat path and where ground moisture enters, and around Fort McMurray the soil freezes deep. It is the most commonly skipped detail.
It only drips when we warm it up. Is the roof leaking? Usually not. Moisture driven into a cold shell during warm-up freezes on the cladding and runs when the building is next used.
