I've made some panels out of Johns Manville SuperDuct RC duct boards wrapped in Guilford of Maine Anchorage. They're huge (70" x 44") and cover the inside of my whisper room. I thought I'd just nail up the panels with small nails since I didn't make frames, wanted the panels themselves to be flush with corners. The question is whether the fiberglass is strong enough to hold its own weight on the wall? Has anyone tried? I have a fear of the panels just sliding down around the nail like butter but I'm not sure if that's valid, or if it's rigid enough to just stay put.
