Excerpt from the substantiation: "The requirement for non-combustible or limited combustible materials is not important. Baffles can be made of wood or even plastic as long as they stay in place long enough for the sprinkler to open. The issue is that they be solid (with no holes that would let the water through) and rigid (so that they do not blow over due to the force of the hot gasses from the fire or the force of the water spray hitting them). If the water spray is impacting the combustible baffle, it will keep it from burning. If the water spray is not impacting the baffle, it will not matter if the baffle goes away because it was not stopping the spray of water anyway." Mike Morey CFPS 3229 .
