\"XPS insulation foam\" with the specialized name of extruded polystyrene, which is also produced by this method, during a process, gives an insulation that has closed cells and has a smooth shell. This insulation, which is similar to Unolith, but is completely different from it in terms of structure, prevents water from penetrating inside and has a very high strength. It is blue in appearance and is also called blue board.\r\nXPS foam is often used to insulate the upper parts of a structure such as walls, ceilings, attics and ceilings, as well as lower parts such as foundations and basements. When this foam is used for upper parts, it can reduce thermal bridging and improve energy efficiency.
