Hello,
Anyone had this issue with areas above suspended ceilings? I have an "attic" composed of non-combustible and limited combustible material. It is steel with noncombustible insulation and an insulation barrier with a flame spread index of 10 on the exposed side (15 on the insulation side) above suspended ceiling tiles with a class A fire rating (flame spread of 25 or under). The AHJ is telling me I need sprinklers in this area because the insulation barrier is not ridged per NFPA 13/2007 8.15.1.2.10. I thought if it conformed to 3.3.11 limited-combustible material definition it would not need to be sprinklered per 8.15.1.2.1. Thanks, Chris Russell t. 360.734.4940 f. 360.647.9540 securitysolutionsnw.com _______________________________________________ Sprinklerforum mailing list http://lists.firesprinkler.org/mailman/listinfo/sprinklerforum For Technical Assistance, send an email to: [email protected] To Unsubscribe, send an email to:[email protected] (Put the word unsubscribe in the subject field)
