Maybe a dumb question but what's the point of insulating a 20-foot container, for example?
I'm going to have a container for some storage of materials and tools during the house construction.
No heating or anything like that.
Does it need to be insulated?
If a container is to be insulated, what insulation should I use and what should I cover it with? Drywall? I will be installing some shelves and other things.
