What kind of energy savings can I expect with a SIPS house?

Compared with a one-inch section of foam insulation in a typical ice chest that will hold ice for five days at 80 degrees F, the SIPS wall and roof sections are 3 1/2" to 12 1/2" of foam insulation. Consider this - a coffee cup is merely 1/16" thick and yet can insulate 210 degree F coffee so your fingers are not burned. It takes less energy to heat and/or cool a SIPS home because of the insulation and the low air infiltration in a SIPS home. Because SIPS homes are so well insulated they require a special and smaller heating and air system. The HVAC system is 60% smaller, resulting in even more energy savings!
