Benefits of using SIPs on this project. Did SIPs help save time, labor, construction costs, or energy?
SIPs simplify the building process. Homes with SIPs are much quieter, they eliminate more outside noise inside the home. This home is built in South Dakota in an open area which is quite windy, SIPs help reduce drafts due to their tightness which is a huge selling point for both energy efficiency and indoor air quality.
