Shipping container spray foam insulation in Picture Butte is closed-cell foam sprayed directly onto the inside of the steel, with nothing behind it. On yards around here the container is almost always the lockable store: mineral and supplement, additive, treatment product, tools, parts and anything that would otherwise disappear. That contents list is what sets the specification.
The corrugations are why nothing else fits
A container wall is a profiled steel sheet with deep ribs. Rigid board can only touch the high points, which leaves a continuous air channel against cold steel behind every panel, and that channel is where the condensation forms. Batt cannot be held in place at all without framing, and framing costs the interior width a container does not have to spare.
Sprayed foam follows the profile exactly and bonds across the whole surface, ribs and flats alike. There is no cavity, so there is nothing for air to reach and nowhere for water to collect. It also adds almost nothing to the wall thickness relative to a framed assembly, which in a box this narrow is a real consideration.
The floor is the surface everybody skips
Container floors are plywood on steel cross-members, and they are the single most overlooked part of this job. Three reasons they matter particularly on a yard like this.
The floor is in contact with the cross-members, which are in contact with outside air underneath, so it is the coldest surface in the box and the one that sweats first. Original container flooring has been treated for its shipping life and has usually had a hard working life since. And on a livestock yard the floor is the surface that takes the boots, the spilled product and the water, so it stays damp longest.
Insulating the walls and the roof and leaving the floor produces a box that is better in every direction except the one where the contents are sitting. Where the container is on skids or blocks with air underneath, spraying the underside of the floor is often the cleanest answer; where it sits on the ground, the inside of the floor plus a hard covering is the practical one.
Setting it down and keeping it dry underneath
A container placed directly on soil traps moisture beneath it permanently, and that moisture migrates up through the floor whatever has been done inside. Blocking the box up so air can move underneath costs very little at placement time and changes the behaviour of the building for the rest of its life. If a container is being set in a new position, raise it and get it level and draining before anything else is decided.
What the contents actually need
Most of what goes into one of these has a label that specifies a storage range, and a bare container breaches both ends of it: very hot in summer sun and at outdoor temperature in winter. Mineral and supplement blends are hygroscopic and will cake with nothing more than a swinging humidity. Anything with a battery in it degrades faster when it is cycled hot and cold. The point of insulating is to make the inside of the box slow and stable, which it can be without any heating or cooling equipment at all.
If the container will be heated, even occasionally, the covering requirement over the foam applies the same as in any building, and a fired heater in a sealed steel box needs its combustion air deliberately provided.

Shipping Container Spray Foam Insulation Picture Butte: Common Questions
Do we need to insulate the floor? Yes, if anything is sitting on it. It is the coldest surface in the box and the one in contact with the ground air, so it is where condensation shows up first.
Can you insulate the outside instead? It is possible, but the foam then needs a coating to protect it from sunlight, and on a working yard it is exposed to damage. Inside is the normal answer.
How much does shipping container spray foam insulation cost in Picture Butte? Priced per board foot over the sprayed area, which on a container is a known quantity. Whether the floor and the doors are in scope is the main variable.
