[GSBN] Looking for experiences with AAC and Rastra

[Chris Magwood]

Hey all!

I'm wondering if anyone out there has much or any experience working 
with Autoclaved Aerated Concrete (AAC) blocks and/or Rastra blocks for 
foundations?

Neither product is readily available here in Canada, but I'm preparing 
some info on insulated foundation options and would like to include 
something about these products if I can get some info. I've obviously 
web-researched both, but I'm looking for actual experience... did they 
meet your cost expectations, were there peculiarities about the install 
process, how would you rate them environmentally, etc?

Feel free to respond to me off-list, as I know this isn't exactly SB 
stuff. However, I'm hoping that among the vast experience included on 
this list would be some hands-on stories about these materials.

Happy holidays!

Chris
