The Parkland comes in two differant versions. The Durotherm Panels do not need to be glued to another substrate. They are used for Garage walls and carwashs. They are a Lightweight but heavy duty PVC material that is 5/16" thick, just hang and enjoy. Of course you might have to trim the material or mask using borders to achieve a 16:9 screen ratio.
The other material is a flimsy Parkland material that is .060 thick and has to be glued to some other material to keep it flat, otherwise you'll get waves.
Both materials have the same exact material on the smooth side. In my opinion a matte white painted wall, fabric, or other material will give the same results. The key is that you don't have texture. Also, you don't want a lot of light to pass through the material, otherwise the picture will suffer. That is why a lot of people use the BlackOut cloth from fabric stores, light will not pass through.
If you really want to get crazy, get some Plexi Mirror and spray the front with MississippiMud paint (an AVS DIY paint).
