Insulation under heated driveway

Use closed cell extruded polystyrene foam board such as Blue Dow Styrofoam or Pink Owens Corning Celfort. The R-value is 5 per inch of thickness. These materials do nor absorb ground water and hence retain their R-value over time. Do not use cheaper molded bead polystyrene foam board as it does absorb ground water and loses it's R-value over time.
