[Greenbuilding] Alternatives to Pressure Treated Wood

[David Bergman]

A side issue here is that, last time I checked, none of the plastic 
alternatives had a flame spread rating. When I've looked into doing 
roof decks here in NYC, where the rating is required if the deck is 
over a certain size, the only viable option is Ipe, because it is fire rated.
