[Cob] Brick roof tiles

[Ron Becker]

While I'm no expert here, but it seems to me that thermal and 
insulation serve two different purposes.  Thermass in walls and floors 
serves a better purpose. Thermal mass in a roof doesn't seem like a 
good idea. It would add a lot of costs to support the weight. This is a 
better place for light insulation. It's much easier and cheaper to 
reflect unwanted heat at the roof's exterior surface. Light clay straw 
might be a slightly heaver but  more desirable option over fiberglass. 
And I don't think clay straw burns very well.

Those who question global warming have a financial or emotional 
interest in the status quo.
