Nominal depth of insulation? The answer, BTW, is YES you can. Deflector distance would be figured from the bottom of the NOMINAL depth of insulation normally stretched from pinched to about zero at the roof/top of purlin to x, nominal depth, at the midspan between 2 Z's.
If ya can't- I know we, and no doubt a lot of others, have a very serious problem. glc -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Gregory Lindholm Sent: Thursday, October 25, 2007 9:06 AM To: SprinklerFORUM Subject: ESFR I have been asked if we can install ESFR heads in a "Butler" type building with 10" purlins. It appears that as long as we keep the deflectors 6" to 18" below the roof deck (8" below the purlins), we should be OK.?? (We do not have the opportunity to use ESFR's with our normal jobs.)
