Our big Irwin has the same set up. The only reason I'm saying big is because the salon 'ceiling' is close to 10 feet wide and 12 long, but the vinyl still looks great, with no sags or wrinkles. Ours utilizes furring strips, 1" insulation, stainless staples, welts(?) and then 3/16" by 1" varnished teak battens attached with bronze round head finish nails. And oddly enough, there are also two areas that have large plastic zippers (about 18") that can open up to feed cables and wires across and forward. But as handy as I am, this is not a project I would take on without some expert assistance.
