Structural Insulated Panels, otherwise known as SIPs, are a relatively new construction material. Composed of a thick layer of foam (usually expanded polystyrene) sandwiched between two pieces of plywood or Oriented Strand Board (OSB). SIPs provide structural framing, insulation and exterior sheathing in a single all-inclusive component. In addition to their use as an external building material, SIPs can be used to construct walls, ceilings, roofs, and on elevated foundations, flooring.

SIPs are engineered in a factory and arrive on the construction site ready to be assembled. Assembly of the panels is quite simple, requiring little, to no, extensive training. No studs are needed as the panels provide all the necessary structural support. Pneumatic nailers are generally used to secure the tops and bottoms of the panels to plates. The exterior walls of a small to medium sized house can be erected in a day. SIP structures are highly resilient, insulated, and energy efficient.

Like convention framing, SIPs can support axial, bending, racking, and shear loads. They can also endure winds in excess of 160 mph and satisfy stringent building requirements for structures located in highly seismic areas.

The wood used in the OSB consists of fast growing hardwoods that can be planted and harvested within a matter of a few years.

Homes built with SIPs offer superior insulation and a tighter building envelope resulting in energy cost savings of 50% or more over houses with conventional framing applications.

Most SIPs come with a ready made chase for wiring the home’s electricity.
