Will post some outside pictures, 2" foam, is form fitted between(snug fit) supports, and adhesived with PL 200, ceiling was pretty easy, made supports out of 1"x 6" x 1/8" Stainless Steel, drilled one end and bent a 30 degree bend in the middle, using self tapping screws, attached to steel and after lubing up panel with adhesive, pressed in place and then tightened tabs to hold in place until adhesive set. You can see the see the tabs if you look closely. And yes a lift is in the future for the new shop, I have a vette and a couple of bikes, figure 2 bays, one with lift for vette and store the bikes under it, when we aren't using the lift for work.
