I'm not sure if the mention of metal back boxes was in relation to my post or another, but to be clear, dry line back boxes are plastic. Furthermore they sit in front of the insulation.
No, it was in the context of the OP's original post.
I know that dry line back boxes are plastic.
Plastic back boxes without insulation behind them will also suffer from condensation as well. Although not quite as badly, and they won't rust. It is still not a good idea though.
