SIP vs Traditional Stick Building
A well built home using SIP will have a tighter building envelope and the walls will have a higher insulation value, which leads to fewer drafts and a decrease in operating costs for maintaining a comfortable interior environment for the
occupants.  Also, due to the standardized and all-in-one nature of SIP construction time can reduced over building a frame home as well as requiring fewer trades for system integration.  The panels can be used as floor, wall, and roof with the use of the panels as floors being of particular benefit when used above an uninsulated space below.
An OSB (oriented strand board) skinned system out performs conventional stick framed construction structurally and maintains the versatility of the stick framed house when incorporating custom designs.  Also, since SIP work as framing, insulation, and exterior sheathing, and can come precut from the factory for the specific job, the exterior building envelope can be built quite quickly.
The EPS (expanded polystyrene)insulation is a closed cell insulation as compared to fiberglass insulation which is an open cell insulation.  Both insulations’ R-values are tested in a laboratory under steady state conditions where there is  no air infiltration.  When a SIP is installed as a wall, foundation, floor or roof system, the EPS is installed in a steady state environment, whereas fiberglass insulations are installed in non-steady state environment.  Research studies show  that the R-values of fiberglass insulation decrease as the temperature differential of indoor and outdoor temperatures increase resulting in higher energy costs to the homeowner.
