Brian stumbled across this video prepared by LiveRoof for their prevegetated modules showing a test to determine flammability of green roof plant material and components. Exposed to flames for 10 minutes, the plant material in direct contact with the fire burned without spreading to adjacent planting.
LiveRoof also has a video on their channel showing a wind test, subjecting the tray system to 110 mph winds for a 2 hr. period with no plant upheaval from the high speed winds.
