I have seen on some home improvement shows, a product that looks like tin ceilings, but is actually made of a plastic material. This is ideal for an outside porch. Can anyone direct me to a dealer or someone that might have this product? I know that Home Depot has a fiber board type 1ft x 1 ft tile, but this would not be good outside. The product I saw on TV was in 2 by 4 ft panels and just nailed up. Any help will be greatly appreciated.
