5/8th drywall, 2x4 stud, insulation, 5/8th drywall again. Metal exterior door. It's not rocket science. You won't need to do anything fancy.

I was wondering about this polyisocyanurate board. It is excellent insulation.

Hasbroh, that doesnt seem like it would do anything lol. Just some foam.

Mojo I like to completely reduce the sound, and have the opportunity the put stuff behind the drywall to completely cut the sound, Id like to take advantage.

Thump, whats that stuff called?

Actually, polyiso is an excellent thermal as well as sound insulation, one of the best. It's not "Just some foam". Usually the better the thermal insulation the better the sound insulation. I made some custom garage doors with 3" board and the sound proofing was extremely good. I was more concerned as to whether anyone has had gassing off problems or any other problems. It has a reflective aluminum skin which would also be good.
