We use double foil faced polyisocyanurate, layered up to the peak of the roof. The seamless blanket of insulation results in minimum air infiltration into the new home. This translates into less heat leaving your house in the winter, and less heat entering your home in the summer. So this reduces your energy costs, which keeps money in your pocket, instead of "out the window"!
