Alden B. Dow - an
architecture student of Frank Lloyd Wright - experimented further with the
concept of structural panels. Dismayed over the lack of proper insulation
in Wright's Usonian homes, concerned about energy efficiency, and fearful
over depleting natural recourses, Dow sought to create a structural panel
with an insulated core. In 1950, Dow did just that and as a result he is generally
credited with creating the first structural insulated panel.
Dow's earliest SIPs were employed in homes located in Midland Michigan. The
panels were composed of 1 5/8 in. styrofoam cores for the necessary insulation
and 5/16 plywood facings to add structural support for the load bearing walls.
These same SIPs were installed over roof framing on 42 inch centers. Many
of these original SIPs can still be found in homes today.
