what is xps foam
Well the hot coffee is kept from scalding your mitts by 1/4â of polystyrene foam. Imagine how well 2 or 4 inches would insulate (Answer: much better). XPS foam board is an insulation material similar to polyisocyanurate in its texture and rigidity. It is usually blue or pink in color, with a smooth plastic surface. Like fiberglass, the pink and blue colors are not natural but part of the manufacturing companyâs marketing efforts.
