It is a paintable plastic. I only know because I make (buildings) and some of the windows are made from that.  

 Polystyrene is a polymer made from monomer styrene, extracted as a liquid from petroleum. It is a thermo plastic which means it can be heated and cooled back to a solid
Actually Styrofoam is a Dow Chemical registered trade mark for foam insulation and does not refer to all polystyrene so that term is misused. Polystyrene comes in small bead format and then is expanded into shapes like coffee cups, clam shell container at fast food outlets etc. There are also hard polystyrene products, like disposable cutlery, plastic containers like yogurt etc. electronic housing for TVs etc. It can come in clear form too.
The white foam polystyrene can be painted with acrylic paint, but the second you use a solvent based paint on it, it will dissolve.
