    I don't think we can say the IFR is always better than cotton. It really depends on usage, staffing, both short term and long term budget, and ability to properly maintain them.

    As a separate backlash to IFR, in high end commercial venues we're seeing a resurgence in natural-based fabrics and designers moving away from synthetics, mostly in regard to 'sustainability'. I've seen more hemp-based fabrics too.

    Full deluge. Looks like the curtain spec was developed assuming or ignoring that the deluge system was going in and certain elements of it were seemingly compromised on when the contractor discovered it wasn't required for code. It was an all-around subpar installation. Unbalanced and triggered a couple times for no apparent reason. Tension lines kept getting snagged on steel connection hardware on the face of the tilt-up panels. To crank it back up you had to dismantle a rope lock from the arbor to get to the crank-side of the braile winch.

    3-4 years after opening an independent rigging contractor was brought in to assess the entire venue and produced a 13-page report of deficiencies...

    Just a few snips from NFPA 705 of interest:

    and

    In my opinion, most of 705 is about not starting a building fire or getting injured while doing the test that proves very little.

    IFR, if they get dusty give them shake.

    IFR Installed ten years ago and still going strong without issues. Dust? The whole dam theatre is a dust magnet, I have dust bunny kick line numbers in some shows.

    +1 for IFR. We've never noticed additional dust collected on ours.

    In my experience its the opposite. With the dominance of IFR in the market its now difficult to find someone to respray them.

    IFR has been industry standard for quite some time. We no longer quote non IFR unless specifically requested.
