Further information about foam core:

Available in a wide variety of thicknesses and sizes, Foam core Building Panels are compatible with virtually any stable substructure. They are lightweight, internally waterproof and dimensionally stable, making them fast, clean and simple to work with. The blue waterproof core is CFC-free, made from waterproof extruded polystyrene foam, reinforced with fiberglass mesh on both sides and coated with synthetic polymer resin mortar which fully embeds the mesh layer resulting in the panel’s strength and the ability to develop highest adhesion strength to virtually any type of thinset mortar. The embedded mesh eliminates the risk of delamination of installation layers.
