How breathable is a straw bale wall? According to Andrew Morrison, a straw bale builder in Jacksonville, Oregon and author of the Straw Bale House Blog, not very. In Morrison's most recent "straw bale minute," he argues that, when covered with an inch and a quarter to an inch and a half of plaster, there is no moisture moving in and out of the straw bale wall. That's news to a lot of straw bale builders and environmental health experts, and some have apparently taken issue with Morrison's claim in the comments section of his blog. Why? Most straw bale builders have long believed that moisture is able to move through straw bale walls and earthen plaster, making the walls highly resistant to mold and rot. Morrison does admit that the jury is still out on the issue, and invites readers to participate in a dialogue on the subject.
Whether you agree with him or not, for a number of reasons, Morrison's blog is an interesting place to spend some time: a) he posts rather frequently, which is relatively unheard of in the world of straw bale blogs, and b) he's passionate about his profession. There are podcasts, videos and reading materials galore—more than enough stuff to keep even the most ravenous straw bale enthusiast busy for quite some time.
