I'm redoing the drop ceiling in my theater room [ Painting the hangers Mickie Mouse Black and wrapping the panels in a black sound transparent material ] I've been think about using ridged fiberglass panels like Owens Corning 703 in place of the ceiling panels around the edges and in the corners of the ceiling because with the wrap on them the would look just like the other panels ....would this help or am I just wasting my time???
