Non-combustible roof decking material (wood-look)

I’m looking to put a deck on our roof. With real wood not being up to code (beyond 1/3 of the surface as far as I understand), I’m looking for a wood-look non-combustible type material _that does not look cheap and plastic_. They used great material at the Australian Pavilion at the Venice Architecture Biennale (see attached photo) but I haven’t been able to track down the specs. Has anyone been down this road and found a great material for this type of project? Thanks for any ideas! Steve

Arch111…my understanding was that non-combustible meant non-combustible for rood decks, and that Ipe was no longer accepted as non-combustible. I’d love to be wrong about this though. Is there a TPPN or Buildings Bulletin that allows Class A, or have you gotten a determination on a project to get it approved? jcarch ———————— James Cleary Architecture brownstoner.staging.wpengine.com/jamescleary

there are wood deck tiles that are Class A fire rated…DOB accepts these as non combustible. http://nyc-dob.com

Thanks August, for bringing up the real question, which of course is which materials the DOB does accept as non-combustible. Apparently both Ipe and wood-glass composites have been accepted in the past, but I would like to be sure before I put any money on this.

Google ‘composite decking’ – some of the more expensive materials look quite good. My architect advised me that the DOB might not accept composite as non combustible (White it is not). Just saying. A different idea would be to use non combustible material on the 3 ft to your property line (stainless steel?) and do the rest with real wood.
