The showcase house incorporates advanced framing techniques which help reduce the amount of material used to build the house as well as provide more space for insulation.  The exterior walls are framed with 2x6 studs at 24” on center, allowing for a thicker insulation layer with fewer interruptions.  The door and window headers are designed to adequately support the structure without being oversized.  There is a layer of foam board in all the exterior headers for added insulation.

 All corners are open construction, allowing for insulation
 to completely fill the cavity, eliminating any cold spots
 in the exterior walls.
 

Additional advanced framing features include
the I Joist floor structure and elimination of
 structural headers in non-load bearing walls,
visible in the center of this photo.
 

Structural studs are made of finger-joined lumber rather and solid material, making better use of resources by using smaller pieces of material which are assembled into straight, strong boards.
