Hi guys, I'm a big fan of using bead board as a bounce material, but sometimes it can be difficult when the gaffer in a new country doesn't know what a bead board is. Sometimes, the material I end up with is a different, harsher material, which renders light less soft. So, I was hoping someone in here could help me clear up my confusion between the many names, Is there anywhere I can read and get good information about the difference between the following? -styrofoam
-polystyrene
-- expanded polystyrene
-- extruded polystyrene
-poly (I'm guessing it is short for polystyrene)
-beadboard
-foam core
Any help would be much appreciated, Thanks,
