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.

Subject: Re: Tyco CC sprinklers / draft curtain
That is what the contractor is arguing. 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 say it does meet it.
Insulation by default blocks heat..

Well, the customer called Tyco and they could not say definitively if the
insulation would meet the requirements or not.

I have a customer that is asking if batt insulation can be secured to the
roof decking and used as a draft curtain for the Tyco CC sprinklers. 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.
