Insulated my container roof and got a surprise puddle
I spent all last month putting foam board insulation on the ceiling of my 40 foot container. Thought I sealed every gap with that spray foam stuff. After the first heavy rain, water was dripping right onto my brand new plywood floor. Turns out I put the vapor barrier on the wrong side, so condensation built up and soaked through. Anyone else mess up their insulation order and have to start over?

Vapor barrier placement is a sneaky one. A lot of folks get that detail wrong their first time. You basically just have to tear it all down and flip the insulation around. At least you caught it before the plywood started rotting out.

Wait, isn't the vapor barrier supposed to go on the warm side of the wall?
