Todd, Take a look at 2006 IBC Table 721.2.1.4(2) "Finish Material" 1/2" GWB = 15 Minutes.
Hope that helps. John Drucker Fire Protection Subcode Official (AHJ) -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Todd Williams - FPDC Sent: Friday, April 11, 2008 7:04 AM To: [email protected] Subject: thermal barrier NFPA 13R includes an exclusion for sprinklers in bathrooms less than 55 sqft and where the walls behind fixtures "are of non-combustible or limited combustible materials providing a 15-minute thermal barrier". Is there any way to quantify if this criteria is met? A thermal barrier to what? I have an AHJ questioning this. Todd G.
