Barn spray foam insulation in Stony Plain is nearly always a conversation about the oldest building on a property, because in this county the original barn is frequently still standing and is frequently the thing the owner cares about most.
The building the family will not take down
It is worth naming this because it changes what an honest quote looks like. A settlement-era barn on a Parkland County yard is rarely the most useful building on the property and is often the one with the most attachment to it. That is a legitimate reason to keep a building and a poor reason to insulate one. Establishing what the owner actually wants from it, which is sometimes preservation rather than performance, saves everybody a wasted survey and occasionally leads to better advice than the one that was asked for.
What timber framing does to the work
The oldest of these are timber framed rather than stick built, with large members at wide spacing, board sheathing, and no cavity in the sense a modern wall has one. Nothing fits between anything, the surfaces are irregular, and the frame itself is a substantial part of the area to be covered. A sprayed layer is the only practical method on that assembly, and the quantity is driven by the developed surface rather than by floor area, which is why a quote on one of these looks high against the dimensions.
Moisture in a building that has never been sealed
These barns have been drying and wetting freely for a century and the timber has reached an equilibrium with that. Sealing the shell changes the conditions the frame has lived in for its whole life, and on a structure of that age it is worth doing deliberately rather than enthusiastically. If the building is going to be closed up, the ventilation has to be designed rather than inherited, and anywhere the frame is in contact with ground or masonry needs looking at first, because those are the points that will hold water once the building stops breathing the way it always has.
The hay mow, which is most of the volume and none of the use
The upper floor of one of these is usually the largest space on the property and has held nothing since the operation stopped baling small squares. It matters to the envelope question because it sits directly under the roof, it is open to the whole structure, and any warmth generated below rises straight into it. Owners thinking about the ground floor rarely think about what is above it, and on a Stony Plain barn the honest options are to leave the mow entirely outside the treated space with a sealed ceiling under it, or to accept that anything spent below will be heating a volume nobody uses. Choosing the first is what makes the rest of the work worth doing.
Barn Spray Foam Insulation Stony Plain: Common Questions
Can the original homestead barn be insulated? Then it is worth asking what you want from it. Preservation and performance are different jobs.
Why is the quote high for the size? Timber framing means the sprayed surface is well beyond the floor area, and the frame is part of it.
Should we seal it up? Only deliberately. A building that has breathed for a century needs its ventilation designed.
