Airdrie has grown fast along the QEII corridor, and a lot of that growth is small business and trades operating from yards and acreages where a container is the cheapest secure building available. Shipping container spray foam insulation in Airdrie is usually a working owner deciding that the box needs to stop wrecking the things kept in it.
The trades yard problem
A container holding tools, materials and equipment is holding exactly the things condensation ruins. Warm damp air from equipment put away at the end of the day meets steel that is well below freezing by morning, and the moisture ends up on the walls, the ceiling and the contents. It is slow, it is invisible for a while, and then a load of tooling is pitted.
Chinook country makes it worse
Airdrie sits in the same chinook belt as Calgary. Steady cold is easier on a container than repeated warming and cooling, because every cycle carries the interior air across its dew point again. That is why boxes here can be wetter than ones in genuinely colder parts of the province.
Closed cell, directly onto the steel
Two pound closed cell sprayed straight onto the interior skin removes the cold surface entirely - no gap, nothing behind it for air to circulate in. Batt is the common mistake: it looks like insulation, but the steel behind it is still condensing where you cannot see it. Closed cell is also its own vapour retarder at working thickness and adds stiffness to a structure that often gets relocated.
Corrugations decide the product
The wall is ridged rather than flat. Rigid board bridges the ridges and leaves air channels; batt has to be furred out at a cost in labour and interior space. Foam conforms to the profile and bonds to it, which is why it is the standard answer for a container rather than an expensive one.
Condensation is the reason, not heat
Most containers are not heated, and the complaint is almost always that everything inside is damp. Steel is the coldest surface available, so moisture collects there and runs down the walls onto the contents. Removing the cold surface removes the mechanism.
Shipping Container Spray Foam Insulation Airdrie: Common Questions
Is this worth it for a storage container I do not heat? If the contents can rust or grow mould, yes. Unheated boxes still condense - they simply do it unobserved.
Will I lose much interior space? Some, at the thickness the duty requires. For a workshop that trade is usually worth it; for pure pallet storage it may not be, and we will tell you which you have.
Do the doors and floor matter? Yes. The envelope is only as good as its weakest part, and door seals and the floor are where a lot of moisture gets in or sits.
Does it need covering if people go in it? Yes. Once anybody occupies an Airdrie container the foam needs a thermal barrier over it, normally drywall or an approved panel.
