Sprinkler Protection of Exterior Glazing

Previous investigations made into protecting glazing assemblies with dedicated sprinklers included protecting wide windows with multiple sprinklers, but they did not address protecting exterior glazing assemblies from external fire exposure with sprinklers. In addition to a summary of the previous work on protecting glazing assemblies with dedicated sprinklers, this paper describes the test set-up and discusses the test results that led to a sprinkler system recommendation for protecting exterior glazing assemblies from external fire exposures.
