Shipping container spray foam insulation in Hinton is frequently asked about for a box used to hold feed, supplement and anything else that has to survive a long winter without being got at, because a container locks, it keeps animals out of it, and it can be put wherever it is needed.
Bought to keep things out, and it does that well
The reason these turn up on properties here is that a steel box is proof against everything that gets into a shed: rodents, weather, and larger animals that will open a feed store given a season to work on it. That part it does properly and it is why owners keep buying them. The disappointment is never security. It is that the contents come out damp, and that has nothing to do with what the box keeps out.
A steel box has nothing to slow the temperature down
The walls are a corrugated skin and there is no mass behind them, so the inside follows the outside almost immediately. Through a Hinton spring that means crossing freezing repeatedly within a single day, and every crossing puts water on the inside of the walls, which runs down onto whatever is stacked against them. Feed in paper or woven bags takes that up readily. Sealing and insulating cuts the number of crossings sharply, which is the whole mechanism and the whole benefit.
Stacking to the walls is what ruins the bottom of the load
The instinct with a container is to use every centimetre, so sacks go right up against the sides and right into the corners. Those walls are the coldest surface in the box, they are where the water appears, and anything touching them takes it up. Leaving a hand's width between the load and the steel, and keeping the load off the floor on a pallet, costs a little capacity and saves the outer layer of everything in there. It is free advice, it applies whether or not the box is ever insulated, and on a Hinton property it is the difference between losing the outside of a stack every spring and losing none of it.
A sealed box holding feed still has to breathe
Sealing a container reduces the temperature swing that drives condensation, and it also means the moisture already inside, in the feed and in the air that came in with it, has fewer places to go. Over eight months that matters. A deliberate low and high vent, or simply opening the doors on a dry day when somebody is there anyway, is what lets the box clear itself. It is a small detail that gets left out of an insulation specification because it is not insulation, and on a Hinton store it decides whether the work delivers what the owner wanted.
Shipping Container Spray Foam Insulation Hinton: The Covering Requirement
Where a Hinton container is only ever a store the covering requirement is assessed on that basis, and where it becomes somewhere a person works or shelters, which happens as soon as somebody puts a heater in one, the thermal barrier requirement applies as it would in any occupied building. Width is the other constraint: a container is narrow to begin with and foam plus a covering takes space off both sides, so it belongs in the plan rather than being discovered when the pallet no longer fits.

Shipping Container Spray Foam Insulation Hinton: Common Questions
Why does feed stored in a container come out damp? Condensation on a steel skin with no mass behind it. It is the box, not what you put in it.
Can we fill it right up? Better not to. Leave a gap to the walls and get the load off the floor. That is where the water is.
Will we lose much room? Some, and in a container that matters. It gets planned in rather than found out afterwards.
