This is in response to your fax dated March 3, 1997 addressed to Mr. Ken Rhodes regarding Garden
Roof surfacing on your UT, Classified roofing system.
From UL's perspective, as well as ICBO's,this is a non-issue. Within the parameters of
ANSTJUL790 (ASTM E 108),this type of surfacing would have no deleterious effect upon the fire
rpcistant nrnnPrtitc elf flip cvet'm WP fpp the nnly rnnncTrn of a incal anthnrity having inricdictinr
should be the waterproofing ability of the membrane underlying the Garden Roof surfacing. This, of
course, is outside the realm of flammability testing.
If you have any further questions on the above, please contact the writer.
