[Greenbuilding] straw clay

[JOHN SALMEN]

Hi Chris,

Locally we have Elke Cole - a trained architect with lots of hands on
experience as a resource with potential model 'code approvals'' for your
area. Call me for discussion on that. 

Leichtlehm or clay/fibre as building science is still a bit out there.
People talk about r values of 48-50 for an 18" wall but all we really have
in terms of science is corresponding values for strawbale which is a little
more investigated and I think the consensus at this point is that it yields
maximum uniform values of about r1.5 per inch which is quite a bit lower -
so that tells you that you can expect significantly lower values with
clay/straw. 

It is a great material however and seems to be working in our climate -
labour intensive.

Hello, 
I'm looking for a source of research in to the building science of straw
clay wall systems. Any pointers?
Cheers,

Chris Koehn
