Hi, First time poster.
I have been looking for different materials to build a tear out of and have found some that interest me.
The first is Alucobond
http://www.alucobondusa.com/
is two sheets of aluminum with a polyethylene core.
Another is Alucore
http://www.alucore.com/english/produkte ... lucore.htm
It is 2 sheets of aluminium with a honeycomb core. (i'm not sure if it's available in the USA but it is available here in Australia)
Both of these are Alcan products.
The last is Symonite
http://www.symonite.com.au/index.htm which is an Australian product similar to Alucobond. Again I don't know if it is sold in the USA. The only downfall is it is only available 4' wide.
I don't know the cost of these yet but I think they are worth looking into.
Bo.
