It seems the best and most common foams to use is what is known as XPS or EPS (same stuff different names) (Extruded PolyStyrene). It's the solid panels of foam sold as home insulation. Either pink from Owen Corning or blue from DOW? I think there's green stuff too but I don't know who manufactures it. The white beaded stuff is not very strong. The extruded stuff is better for our needs.
