SIPs, or Structurally Insulated Panels are gaining popularity for their ability to provide both strong and energy efficient pre-fabricated panels for use as walls, floors, and even roofs.  These are essentially engineered laminations of OSB sheathing material and Expanded/Extruded Polystyrene Insulation.  How soon will we see these hit our market?  Likely not as a dominant fixture immediately, however in colder climates certainly quicker.  But, as we look forward to new energy requirements in 2014, we will need to start considering alternatives such as SIPS to improve on our current techniques without having to significantly increase assembly thicknesses.
