A glass wall assembly was exposed to an intense
real-scale compartment fire. The wall assembly consisted
of four glass sections, two of which were fitted with
tempered double-pane glass and the other two sections
were fitted with tempered single-pane glass. At each
glass section, temperatures were measured at the exposed
face and the unexposed face. Total heat flux gauges were
used to measure both the temporal variation of the
energy incident on the glass wall and the transmitted
energy rate detected through two of the glass sections.
Visual and infrared cameras were used to image the
unexposed face of each wall assembly during the fire
exposure. Results of glass breakage and subsequent glass
fall out were compared to studies in the literature for
glass sections exposed to compartment fires. The
behavior of the glass wall assembly under a fire load is
