Best Way to Frame and Insulate a Shipping Container in a Mixed Climate (-30°C Winters, +30°C Summers)
Hi guys,
Starting the process of building out a shipping container storage unit on my property and want to make sure it's done right and has an airtight envelope that isn't prone to moisture, condensation, mold, etc.
I was wondering what the best way to frame the inside would be. I've heard from suppliers that some use metal studs, some glue them to the shipping container walls, and others use 2x4s. In all cases, they use spray foam to insulate/vapor barrier. Would then finish the interior with 1/2" bare plywood. The floor would be a bit different using rigid foam insulation, wood block spacers, and 1/2" plywood floor maybe with an epoxy finish. Spray foam thickness would vary from 2" on the walls to 2.5 or 3" on the ceiling.
Is there a best practice here? I'm mainly concerned about condensation and mold in a climate with -30 winters, +30 summers, and high humidity.
In terms of interior climate control would be running a mini-split, radiators and a dehumidifier.
Any input is appreciated. Thanks!
