MEPS foam board insulation, often called beadboard, is made by mixing unexpanded polystyrene pellets or beads containing pentane with a blowing agent. The resulting mixture is poured into a closed container and heated. The heat causes the beads to expand to many times their normal size. The mixture is then poured or injected into a mold, more heat is applied, and the resulting foam blocks are shaped into insulation. #insulation #adlamfilms
