Machine shed spray foam insulation in Lloydminster is applied to the underside of the roof deck and, where the building earns it, the walls. These are unheated buildings and the work is not about warming them. It is about what forms on the equipment inside.
Why the machines are wet when the floor is dry
This is the observation that explains the whole job. A large machine is a lot of steel, and steel holds its temperature far longer than air does. When a mild day arrives after a cold spell, the air in the building warms within an hour and the machine does not, so moisture in that air condenses onto the coldest thing available, which is the equipment. The floor stays dry because it warmed with the air. Owners see wet machinery in an apparently dry building and look for a leak. There is not one.
Equipment that is worth more than the building
The reason this is worth spending on is the ratio. A shed of this type is a relatively cheap structure, and what is parked in it on a Lloydminster farm or yard is frequently worth many times the building. Once it is put that way the decision is straightforward. The envelope is protecting an asset rather than saving on running costs, and there are no running costs on a building nobody heats.
Sprayers, and anything with chemical in it
Some contents are more sensitive than others. Sprayers, chemical handling equipment, anything with seals and elastomers, and any product left in a tank over winter all suffer more from cycling than from cold. Freezing and thawing repeatedly is harder on a seal than staying cold, and a chemical that separates does not always come back. Where a shed holds that kind of equipment the case for treating it is much stronger than for a shed holding a disc and a set of harrows.
What the roof plane alone will do
The practical scope on most of these buildings is the roof deck and nothing else. It is the surface that loses heat to a clear sky, it is where the condensation forms and drips from, and it is the largest single area in the building. Treating it removes the cold surface overhead and slows the swing inside enough that the equipment stops getting wet. Walls add to that and they add cost, and on a shed used purely for parking they frequently do not earn it.
Machine Shed Spray Foam Insulation Lloydminster: Common Questions
Why is the equipment wet and the floor dry? Steel holds cold longer than air does. The air warms, the machine does not, and the water forms on the machine.
Is it worth insulating a building we do not heat at all? That is the normal case. This work is about the surface temperatures inside, not about heating.
Roof only? On most sheds, yes. Walls follow only if the building is worked in rather than parked in.
