For Robert Shadbolt (et all) -- Besides the European fire tests, there have 
been some in the US.  Stuccoed (one-coat) straw-bales passed a 2-hour (ASTM 
119) fire test, which gives them a commercial rating.   Also they passed a 
flame spread test.  The results of both of these tests should be on the 
Development Center for Appropriate Technology (DCAT) web site at www.dcat.net
