A masonry heater is the focal point of this super insulated home. Under the basement slab and around the foundation boast 6” polystyrene insulation at an R-22. The first and 2nd floors 8” SIP walls with “Neopor” foam raise the insulation level to an astonishing R-40. The roof is insulated with a combination of open cell Icynene and cellulose to an R-60. Add in triple pane fiberglass windows and you truly have a “High Performance Home”.
