I recall a discussion about a house that Paul Lacinski brought to
GSBN about the McSweeney house back in 2005. Among other
contributing factors: <br>

The discussion starts at

of our illustrious members weighed in. <br>
<br>
There are certainly other discussions related to moisture,
moisture transport, etc in the archives. A simple google search
of a phrase like 'GSBN moisture' or 'GSBN moisture failure' or
similar should zero you in on whatever you might need from our 18
years of archived discussions. <br>

Happy hunting!<br>

<br>
I'm working on a "defense" of the vapour permeable nature of straw
bale walls for a building code for an alternative solutions
application here in Ontario.
<br>
<br>
The building department is particularly concerned about the lack
of a vapour barrier in the system (again!). I'm pulling out all
the usual test documents and building science theories to help
make our case.
<br>
<br>
But I'm interested in knowing if any of you out there have
actually encountered a bale wall that has failed due to moisture
migration through the wall, especially during the winter. I've
certainly seen some damage done by consistent exposure to rain, or
leaky roofs, or other bulk-water intrusions, but I've never seen a
moisture migration failure. If that has been the general
experience of this list, with its wide variety of climates and
building styles, then that would seem to me to make a good
evidence-based defense for this.
<br>
<br>
And if you have seen such a failure, I'd be interested in knowing
about the suspected (or known) causes, the conditions that led to
this failure, and whether or not the situation was able to be
remedied.
<br>
<br>
I don't need everybody on the list to respond... perhaps only
those who've seen examples of this type of failure. If the list is
silent on this, I'll take that to mean that this really hasn't
shown itself to be a major issue, and will say so in my AS
application.
<br>
<br>
Thanks all!
<br>
<br>
Chris
