FPSFs increase home energy efficiency because the slab edge is insulated. They provide frost protection equal to or better than that provided by deep foundations because FPSFs are based on stringent ground conditions using the coldest winter temperatures likely to occur in each area of the country in 100 years. In addition, raising the frost line reduces construction costs by decreasing excavation depths and disturbs less soil on the site.

Also, the Bear Creek Dome footings have more insulation than usually required.
