For noise: I insulated the entire shop with rockwool. I found the noise coming through the doors was very minimal at that point. So little in fact that noone ever complained. To finish the doors, I would like to do rockwool again, but will have to decide on either 1/4" panels to hold it up, or possibly a fabric of some sort. I'm hesitant because: I threw a few old rigid foam panels up in it to test it out last summer. While it did reflect the heat nicely, it also added weight to the doors. My doors aren't powered, and it's an obvious difference in weight with just the panels. So, I have a mild concern about the doors becoming harder to open and easier to accidentally slam shut.
