I believe NFPA 2007 has addressed this issue. I am researching that now. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Maag, Barry Sent: Tuesday, August 05, 2008 9:08 AM To: [email protected] Subject: RE: Floating Ceilings
I have seen these types in the past and the "space" around the floating ceiling was used for the return air for HVAC. This made the area above the ceiling a plenum thus requiring sprinklers -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Rick Green Sent: Tuesday, August 05, 2008 7:59 AM To: [email protected] Subject: Floating Ceilings I am in the design phase installing wet pipe sprinkler systems protecting new schools. I have noticed that in several of the rooms in the schools(cafeteria, band room, main corridor that runs the length of the school), architect has designed lay-in ceiling systems with gaps ranging from 4" to 12" along the walls and between sections of ceiling within the rooms (floating ceiling sections). I do not believe my non-combustible concealed space above the ceilings is concealed anymore and may require protection. Has anyone dealt with this? I have heard some discussion that if the total square feet of the openings is below a certain percent of the total square foot of a space, sprinkler protection above the space may not be required? Interesting thing is that the school is being built as a "Green" project and seems like the designed openings would make the schools less energy efficient. Anyone's help would be most appreciated...
