Re: [papercreters] Roofing

i like the idea of using tires but am a bit concerned about
outgassing?if they are buried, maybe less a problem for that but maybe
still they might leach? i am thinking of wrapping tires in magnesium
concrete and cloth & netting to sarcophagize the tire material, a
little bit in the spirit of Trash Rocks? Would a cloth and concrete
layer over the weatherboards then rendered with papercrete be a way to
cover the tread weatherboards? i honestly don't know if i could cut a
tire up though! in a bushfire zone, would this arrangement be a way
around the risk of exposed tire burning?
