It does not offer twice as much thermal resistance or twice the energy savings.

Installing more insulation in your home increases the r value and the resistance to heat flow. R value measures how well building insulation can prevent the flow of heat into and out of the home. For example a 1 1 2 inch 3 81 cm thick door without a window offers more than five times the insulating value of a solid wood door of the same size.
