Perhaps the greatest reason of all why SIPs are exploding into the marketplace is because of their superb energy efficiency and superior thermal performance. An analysis conducted by the Oak Ridge National Laboratory (ORNL) compared the average insulation value (whole-wall R-value) between a SIP wall and some other traditional construction wall sections. Their study determined that a 3.5 in. EPS core SIP outperformed its counterparts in thermal efficiency. There results are tabulated in the graph above.

One of the major concerns for any homeowner is the inability to control rising energy costs. Recently, there have been spikes in propane, heating oil, electricity, and even the labor associated with felling, splitting, and drying wood for home heating. However, SIPs offer a window of hope; SIPs are virtually airtight due to the nature of their fabrication and installation. As a result, the occupants have much more control over their interior environment.
