Don't forget that "fire retardant" means a small-scale ignition source
won't ignite it. It does not mean that, in the presence of a fire, it
won't melt, vent heat to the area above, and drop down and obstruct
sprinklers below it.

Lots of church questions this week.
These panels are fire-retardant as required by the Fire Code. We couldn't
have the drop into the crows as that would pose a further hazard for egress.
The panels themselves are in 12ft lengths - the exact width hasn't been
determined but should be no more than 24" wide. The panels will be screwed
into the plywood roof decking at currently unspecified intervals.

Subject: Re: Lapendary Panels
Jim,
This is somewhat similar to the problem I have described in a church
sanctuary. The difference is that my project has the fabric tensioned
around a frame. Joe's response is probably on target, except the
design that I got from the Engineer on my project is nothing that I
would put my stamp on. I'm assuming that these are continuous pieces
of fabric, so the idea of a magnetic release hooked up to a detector
is out of the question.

I have a church being built with a large auditorium. There will be an open
ceiling exposing the roof structure: metal trusses with a plywood roof
decking. For sound deadening, there are installing "lapendary panels" as
seen here:
http://www.mbiproducts.com/products/photos.aspx?ProductID=4000-1010P The
most appropriate photo is in the second column, 3rd photo down from the
top.
The "fabric" panels will run essentially parallel to the roofline - between
the trusses.
We are looking at the best way to sprinkler the room. Do we install
sprinklers below the panels or above or both? Our concerns are that
sprinklers above will be obstructed by the panels and/or sprinklers below
might not collect enough heat to fuse the sprinklers. Any thoughts?
