I use these for ceiling panels. My house, which I built myself, doubles as an art studio, and the ceilings run in three high parallel barrel vaults. The insulation lies on rigid foam, which lies on cross ties, and the barrel vaulting is shaped by using two by fours on top of, and perpendicular to, the crossties. It's simple, light in weight, and attractive, and I wanted the ceiling to be light and the panels to be easily removable for access to the insulation and the underside of the roof. The painted panels simply slide in,without nails or screws to hold them, above polyurethaned one by two furring strips that are screwed to polyurethaned crossties. The panels don't warp or sag and are strong enough to easily support half inch sound board. Each of these panels is flat. However, I know now that I could have designed the ceiling with long curves, as these panels are just flexible enough for that. In places the panels are stained with a golden teak stain and the effect is beautiful. As strong as the panels are, their weight is such that a quite large ceiling, whether curved or flat, is possible, and one person can do it all, even up high.
I also use this material in the kitchen, where they have a gloss polyurethane finish, and my large paintings are in cabinets that have these panels as a back. The surface of these panels, straight from Home Depot, is of such high quality that I easily get a tight seal whereever it's needed.
Use a fine toothed plywood blade and you'll get precision cuts. Finsih nails or small screws are perfect for holding where you need that.
I will continue to buy these and store them until the price goes up. .
