Add "eco material" to that description and it becomes an old
quest of mine. Are you talking about something to sit directly on the
"real" roof? About the best I could come up with when I last
tackled the question was lightweight concrete roof pavers -- not all that
eco though maybe there are some made with flyash.<br><br>
In terms of wood, NYC used to accept Ipe, but I heard a rumor they
stopped when the fire rating claims didn't prove out. And, of course,
there was the rainforest sourcing issue.<br><br>
I've looked for fire-rated recycled plastic lumber from time to time, but
have not yet found any. (Tim V-K: any updates you've heard of?)<br><br>
There is a group called Brooklyn Bridge Forest
(<a href="http://www.brooklynbridgeforest.com/" eudora="autourl">
http://www.brooklynbridgeforest.com/</a>) that is trying to set up a
sustainable source for greenheart for maintaining the Brooklyn Bridge.
I'm not sure what kind of fire rating greenheart does or doesn't have.
(According to one site I just googled, it carries a
"high/medium" rating.)<br><br>

Can anyone suggest a lightweight non-combustible deck material for a roof
deck?<br>
In New York a brownstone has an average flat roof of 700sq.ft. The law
only allows 20% of it to be covered with combustible decking, which isn't
much of a deck. Yet the non-combustible decking is too heavy for the old
roofs.<br>
Suggestion?<br><br>
