Shipping container spray foam insulation in Rocky Mountain House is closed cell foam sprayed directly onto the inside of the steel with nothing behind it. These are everywhere on properties around this town, and most of them are working stores rather than sheds.
A box on an acreage with no power run to it
This is the difference from a container on a serviced yard. A great many of these are parked well away from the buildings, with no electricity anywhere near them, which removes every option that depends on running something: no heat, no dehumidifier, no air movement, nothing. The only thing that can change the conditions inside is the box itself. That makes the envelope the entire solution rather than one part of it, and it is worth saying because owners frequently assume a small heater is the answer.
What the swing does between a sunny afternoon and a clear night
Thin steel with nothing behind it follows the weather closely. On a bright day the sun loads the skin and the inside runs well above outside; after sundown it radiates to a clear sky and drops below outside. That happens repeatedly through the shoulder seasons, and every time the direction reverses the air inside gives up moisture onto the coldest surface available. That is the mechanism behind the rust and the damp, and it is a swing problem rather than a cold problem.
What has to be true about the steel before spraying
Foam bonds to a sound, clean, dry surface and it does not bond to anything else. On a used container that means the inside skin has to be checked for surface rust, for old adhesive and residue, and for anywhere water is still getting in around the doors or a repaired panel. The timber floor gets the same treatment, because it has absorbed whatever was ever spilled on it. All of that is settled before a quote rather than discovered on the day, because it changes the preparation and therefore the price.
Used as a workshop, which changes the requirement
A fair number of these end up as a workspace rather than a store: a bench, a light, somewhere to work on something small out of the weather. Once somebody is spending time in it, the requirement changes and the foam has to be covered. It is worth being clear which of the two a box is going to be before anything is priced, because a storage container and an occupied one are genuinely different quotes.
Shipping Container Spray Foam Insulation Rocky Mountain House: The Covering Requirement
Where the container is occupied, the foam does not stay exposed. A container in Rocky Mountain House that people spend time in needs a thermal barrier over the foam, usually a sprayed coating or a light lining, and that is priced with the job. A box used purely for storage is quoted differently and the difference is stated rather than assumed.
