This retail project has a series of fabric awnings that are fairly large. Have you come across fabric awnings that qualify as non-combustible or limited combustible to the extent that sprinkler protection is not required beneath? Looking for guidance to provide to an architect client.

If the fabric is breathable, I think I'd go with the argument that there's no place for the heat to collect and activate the sprinklers. Still, if the space is occupied, it should be sprinklered.

Agree with Pete, and would further state that if it's fabric, it is quite possible it will melt or burn, or otherwise be breached by the fire before the sprinklers are activated. NFPA 409 deals with fabric aircraft hangers, and it doesn't require fire sprinkler protection for such fabric structures due to the fact that the fabric will be penetrated by the fire before the sprinklers activate, so there will be nothing there to hold the heat, rendering sprinklers ineffective.

Some jurisdictions (i.e. San Diego) have local ordinances that require protection of below of canopies, regardless of the material of the canopy itself if anything will be stored beneath it.
