Premier SIPs were a "must" for this beautiful, rustic, private home as required by the homeowners.
Why SIPS?: Due to the energy savings, and air-tightness of the building envelope, the owners were able to optimize the ductless heat pump system, the energy-efficient gas hot water heater, and the other energy-efficient equipment and features in the home. "We saved money on the SIP materials and construction time when compared to alternative methods and materials needed to achieve the same level of energy performance."
