This sample is a look into low density insulation foam as a core. Two additional experiments are piled on top. The first is a combination of XPS foam with thinner higher density core to create a harder outer surface. The second is the use of a very heavy (as these things go) polyester veil against the mold surface. Neither of these is a huge success, but there is some value here in showing suboptimal things - to be improved on or avoided!
