Polystyrene is known for being waterproof thermoplastic foam that most people resort to when they need a good temperature and sound insulation material. You can find two types of polystyrene available on the market and those are extruded (XEPS), which is also known as Styrofoam, and expanded (EPS) and the main differences between these two lie in cost and ratings, needless to say that the former one has higher R-value than the latter one.
