Machine shed spray foam insulation in Lacombe is applied to the underside of the roof deck and, where the building earns it, the walls. Nobody heats these buildings and the work is not about heating them. It is about what forms on the equipment while it is parked.
Equipment that sits from harvest to seeding
The storage period here is the better part of six months, and the machine that goes in after harvest does not move again until the ground is fit. Whatever the building does to it, it does for that whole period rather than in a bad week. Nobody inspects anything during it and the first proper look happens in spring, at the point when there is no time to deal with what is found.
The roof deck is where the water is made
On a clear night the roof sheet loses heat to the sky and drops below the temperature of the air inside the building. Moisture in that air condenses on the underside of the deck, and because it forms overhead it lands on whatever is parked below rather than on the floor. Insulating the deck removes the coldest surface in the building and slows the daily swing, which is what actually stops the cycle instead of merely reducing it.
A wet spring, and what the floor does
Central Alberta ground holds water, and a shed on a clay pad with no vapour control under the floor takes moisture up through it for weeks in spring. That is a second source on top of the air, and it turns up as damp at the base of the walls and on anything sitting directly on the slab or on gravel. It is worth establishing whether the floor is contributing before deciding the scope, because sealing the shell over a wet floor moves the problem rather than removing it.
The corner where the chemical and the seed live
Almost every machine shed here has a corner holding things that are not machinery: treated seed left over, chemical, oil, filters, a shelf of parts. Those are the contents that actually suffer from a building that cycles, and they are also the ones with a temperature range printed on them. Where that corner exists, partitioning and treating it properly is frequently better value than treating the whole shed, and on most Lacombe yards it is the recommendation that actually gets acted on, because the number is small enough to approve without a longer conversation about the building.
Machine Shed Spray Foam Insulation Lacombe: Common Questions
We do not heat it. Is this worth doing? Yes, and that is the normal case. It is about the surface temperatures inside, not about heat.
Why is the equipment wet in an apparently dry building? The deck drops below the inside air on a clear night, water forms overhead, and it falls.
Roof only? On most sheds, yes. The exception is a corner holding chemical or seed, which is worth partitioning.
