The AHJ is going to have to make the final call. My pay scale isn't high enough to make those types decisions, but if it were, I'd say no. If water spray from the 1st sprinkler or 2 damages the insulation to allow heat to flow past it, you've lost your heat barrier and the 1000 sf design area is out-the-window.
Back to my regularly scheduled program.

The NFPA 13 definitions of draft curtains are in reference to separation of ESFR and SR, water spray systems and hazard separation. It is an outside the box thinking for sure. As you say, if it is stapled to the deck, that would prevent heat from passing through and over. That is the only criteria in the datasheet.

I have never seen an application such as this, but it doesn't seem to be prohibited in the datasheet. The only requirement is that it must be constructed of a material so that heat can not pass through or over. >> >> What do you think? Could insulation secured to the roof/floor deck serve as a draft curtain for these sprinklers? My gut feeling is that it would not be suitable, but I can't find something in the data sheet to support that. My only thought is that activation of a sprinkler could possibly knock the insulation down. >> >> -- >> Travis Mack, SET >> MFP Design, LLC >> 2508 E Lodgepole Drive >> Gilbert, AZ 85298 >> 480-505-9271 >> fax: 866-430-6107 >> email:[email protected] >> >> http://www.mfpdesign.com >> https://www.facebook.com/pages/MFP-Design-LLC/92218417692 >> Send large files to us via: https://www.hightail.com/u/MFPDesign >> >> _______________________________________________ >> Sprinklerforum mailing list >> [email protected] >> http://lists.firesprinkler.org/listinfo.cgi/sprinklerforum-firesprink >> ler.org > _______________________________________________ > Sprinklerforum mailing list > [email protected] > http://lists.firesprinkler.org/listinfo.cgi/sprinklerforum-firesprinkl > er.org > > _______________________________________________ > Sprinklerforum mailing list > [email protected] > http://lists.firesprinkler.org/listinfo.cgi/sprinklerforum-firesprinkl > er.org _______________________________________________ Sprinklerforum mailing list [email protected] http://lists.firesprinkler.org/listinfo.cgi/sprinklerforum-firesprinkler.org _______________________________________________ Sprinklerforum mailing list [email protected] http://lists.firesprinkler.org/listinfo.cgi/sprinklerforum-firesprinkler.org
