Considering this, what is Styrofoam used for?

Styrofoam is a trademarked brand of closed-cell extruded polystyrene foam, or XPS. This foam is also referred to as “Blue Board” and is used for building insulation, thermal insulation and water barriers.

Furthermore, is Styrofoam water resistant? Although it is a closed-cell foam, both expanded and extruded polystyrene are not entirely waterproof or vaporproof. Extruded polystyrene is also permeable by water molecules and can not be considered a vapor barrier.
