"An ICF home, like one built with Fox Blocks, provides many of the essential features that today’s homeowner is looking for: excellent indoor environmental quality (IEQ), energy-efficiency, and disaster-resistance. Specifically, ICF homeowners can expect the following benefits over a wood-frame home: 20 percent or more energy savings, 10-30 percent less outside air infiltration, a 4-hour fire rating, twice the strength, and three times quieter."
