I believe that means a HE foam system plus a sprinkler system with a .30
density.

NFPA 13, 2014 Table 18.4(a)

Some "Sprinkler Discharge Densities" are given as (for example):

"0.30 plus high expansion foam"

Does this mean the roof system needs to be high expansion foam with a
density of 0.3? I'm just confused with the use of the word "plus" and want
to make sure it doesn't mean anything else.

Thanks,

Tony
