Experimental investigation of flame impingement on vertical and inclined glazing facades

Breakage and fallout of glazing systems create openings in an enclosure that affect the fire growth and the development of post flashover flames emerging outside of the openings. The behaviour of glazing is the result of its thermally induced stress response to the heat fluxes from the fire in an enclosure. In recent times building façade designs have evolved and now incorporate many different shapes, orientations and materials. The conventional single and double glazing panels have been surpassed by composite type glazing systems which include glazing and transparent resins. This paper presents experimental testing of these composite glazing panels subjected to localized fires, which have the same fire load. The effect of localized fire on the materials tested as seen in the final char patterns on both glazing systems is note-worthy. The paper also includes details of comparative calculations with EN 1991-1-2. Furthermore, results of detailed material analysis testing of the intermediate transparent resin within the glazing sandwich panels are included.
