[Greenbuilding] fireproof light deck

Fri Apr 8 09:29:45 CDT 2011

My only intersection with it was to price it for a large deck and 
stairs (on a tight budget) in California and it was more expensive 
than local redwood -- enough more that I couldn't convince the client 
to go for it.  But it did look  like an interesting alternative. (I 
wasn't overjoyed about the selection of redwood.)
