They are not supposed to be made from hay, just straw. Straw is mostly cellulose fibre, and apparently somewhat termite resistant. Hay as different characteristics and is undesirable in the bales.

Does the government require a warning notice on it to tell people who get hay fever that it may affect their health; especially if they are pregnant.

well some are trying to do the weird green thing.  check out that is the California Straw Building Association CASBA -- yes walls made of strawbales in high seismic zones (tax credit for using straw too!)  a few years ago they got money from the state to do a structural testing program on strawbale walls and shear walls (testing research papers at  the result is a new book by Bruce King titled Design of Strawbale Buildings (the nerdest strawbale book ever)  they did a full scale test of a plastered strawbale wall (got about 610 plf  as a design value) (they also passed a 2-hour ASTM fire test). CASBA also has a draft appendix for strawbale construction before the California Building Standards Commission.


I have designed quite a few strawbale buildings. anyway check out the resource list from the CASBA website for engineers and firms that are building with straw and thinking of the world in a different way.


wow ! !  it looks like I over spent my $0.02
