As a result, building costs were reduced because traditional framing, insulation, and drywall were not required.
The panels have a foam core that is four to eight inches thick (depending on the needed R value for insulation). The wall SIPs have an insulation value of R-25 and the roof is R-32. Unlike conventional framing, the panels maintain their strength without requiring wood studs inside the panel. As a result, there are no breaks in the insulation and much less lumber is used.
Inside, the face of the structural insulated panel walls was left exposed, conserving resources, saving money, and serving as an education tool. The designers capitalized on the aesthetic effect of a raw-looking interior, intentionally emphasizing the beauty of the unfinished look.
