[Sprinklerforum] Re: Ceiling Heights for 5.6K Heads

[Mike Stewart]

Yes…and no… Before the 2025 version of NFPA 13 there are no restrictions accept for in storage occupancies. The new NFPA 13 (2025 Ed.) introduces new restrictions for ceilings over 30 feet in height. These restrictions include limiting sprinkler types, minimum K factors, minimum density requirements and design area.  Mike Stewart Unemployed Dog Walker  On Nov 4, 2024, at 4:54 PM, Jackie Ward <jw...@firetrol.net> wrote:  FMDS 02-00 (Jan-2024) unobstructed construction Table 2.5.2.3.1.1(a) limits 5.6k for HC-1 to 60’ ceiling height.
