Oops! Sorry! I was mistakenly looking at Table 16.2.1.3.3.1 when I references Curves A & B. In Table 16.2.1.3.3.2 both conditions use Curves C & D, but for encapsulated you increase the density by 1.5.

For nonencapsulated you need 1 level of in-rack sprinklers and you pick your density and design area based on Curves C or D. For encapsulated you need 1 level of in-rack sprinklers and you pick your density and design area based on Curves A or B and then you increase the density by a factor of 1.5.

Class IV Encapsulated- 18'-0" Table 16.2.1.3.3.2 tells me to go to Figure 16.2.1.3.2(d). The Figure description says "Class IV Nonencapsulated". But the table has "Yes" for encapsulated.
