What are SIPS?
SIP stands for Structural Insulated Panel.  Most SIPs consist of two layers of wood sheathing laminated to a foam core.  Some SIPs come with other facing materials: metal, drywall, fiberboard, even plastic.  When installed in a home, the SIP provides both structure and insulation.  While most commonly used in walls, SIPs can also serve as load-bearing floor, ceiling and even foundation components.  Most SIPS are designed carry the entire range of structural loads in a building; however, SIPs with one drywall facing are just used as cladding panels around timberframe structures.   (Note: A related category of SIPs doesn’t use facing materials; they use either wood or steel framing members placed between or within tall blocks of foam.)

What gives  SIPS their strength?
The resulting sandwich panel product acts like an engineered I-beam, resisting both compressive forces from above and buckling forces from the side.  Engineering tests show that, depending on the type of structural test being administered, SIPs range between two and seven times stronger than traditional framing.  In some SIPs, integral studs used as splines for joining panels together also help carry the structural load.

What makes SIPS highly energy efficient?
Four key factors make the average SIP home very energy efficient.  First, foam provides higher insulating value per inch than traditional fiberglass insulation.  Second, there is much less wood framing within the typical panel, which again increases total R-value.  Third, the foam is continuous and is not susceptible to the commonplace flaws found in average batt installations.  Fourth, foam doesn’t allow air infiltration around it; with reasonable attention to detail, panel joints can be sealed to provide house tightness that averages between 20% and 40% (for house with wall and ceiling panels).
