Fanfold insulation is an extruded polystyrene foam insulation which is designed to be applied to the exterior walls of homes, between sheathing (or pre-existing sidings) and usually vinyl siding. Its purpose is to provide thermal protection and to form a second barrier between the elements and the framing.
