A view into the furnace
about 10 minutes into the test. The plastic web
connectors glow as they begin to burn.
As the
temperature reaches the maximum, the entire wall
glows red hot.
As the clock approaches the
3-hour mark, the foam on the outside of the wall is
uncompromised.
Immediately following 3 hours
of testing, the wall is removed from the furnace
and sprayed with a high
pressure fire hose for 2-1/2 minutes
continuously.
Steam explodes
as the wall surface cools, etching the concrete
finish about a 1/4 of an inch deep.

stands in the front of the post-test wall which
is loaded down with 12,000 lbs per lineal foot
of pressure.
A close-up view of the
smoothed, etched surface of the post-test wall
shows very small web sections.
