Barn spray foam insulation in Lacombe is work on buildings that are frequently older than anything else on the property. Central Alberta is full of large timber-framed barns from an era when a farm was run differently, and most of them are no longer doing the job they were built for.
The big old barn that is no longer a barn
Walk a yard around here and the barn is usually holding storage, a few horses, equipment, or nothing at all. It was built for dairy or for draft horses, with a hayloft above and stalls below, and the farming that justified it stopped decades ago. That matters because the building is enormous relative to what it now does, and any conversation about insulating it has to start with what the owner actually wants from it rather than with the building itself.
Sills, roof and foundation come before any foam
This is the honest part of the visit and it comes first. A timber-framed barn of that age may have a sound frame and a failing roof, sills that have gone at ground level, or a foundation that has moved under one corner. Foam applied to a building that needs structural repair is money placed on top of a problem. On a fair number of these the recommendation is to spend on the roof and the sills first and revisit the envelope in a few years, and on some of them the envelope work is not justified at all. Being told that costs a sale and saves an owner from a bad one.
What a hayloft roof does to the volume
The shape works against heating. A barn of this type has a very tall interior with the loft above, so the volume is several times what a modern building of the same footprint would hold, and warm air goes straight up into a space nobody uses. Anybody planning to heat the whole thing should see that number first. The arrangement that works far more often is to treat and use part of it, with a ceiling put in at a sensible height, and leave the rest as it is.
Treating the part that is actually used
That is the practical answer on most Lacombe barns. Partition the area that has a use, insulate that properly including a new ceiling plane, and let the remainder stay an unheated storage volume. It costs a fraction of the whole building, it produces a space that genuinely works, and it does not commit the owner to warming a structure that was designed for animals that left in 1955.
Barn Spray Foam Insulation Lacombe: Common Questions
Can you insulate the whole barn? You can, and on a building this size you very likely should not. Treating the part you use is the better spend.
Is ours worth doing? The structure gets assessed first. Roof and sills sometimes come before any insulation.
What about the loft? It is most of the volume and none of the use. A ceiling at a sensible height is usually the answer.
