Does anyone have access to 13 where the water curtain detail still
required open sprinklers (deluge)?
I'm curious if the draft stop is required.
Besides smoke protecting the opening it occurred to me the other day
the draft stop would help form a 'wall of water' by blocking ~9 gpm,
making it drop straight down, and thereby providing a density of
greater than 1 gpm/sf around the perimiter.
