How to insulate a shipping container home?
I would like to understand how to best insulate a shipping container home. i am thinking of building on a pier system.
Specifically I am wondering about the double sided foil such as Radiant guard that comes in both permeable and vapor barrier. Which do I put on the inside and which goes on the outside. I live in the Seattle area Marine Zone 4-5.
What insulation do I use in combination with this radiant barrier on the inside or the outside. I want to add outside cladding to my container such as Cedar siding and will add a roof deck which will have drainage under it away from the roof therefore I am thinking I will be able to add insulation on top of the outside.
Should I use spray foam on the underside?
