Disappearing attic stairways are convenient for accessing storage space but hard on heating bills. The Energy Guardian is a tight-fitting, high-density, expanded polystyrene box that seals up the areas around your attic's access door.

According to the manufacturer, a properly installed Energy Guardian will reduce heating and cooling expense by 15% or more. Installation requires no cutting or measuring; just minor assembly.
