Re: GSBN:strawbalebuildings in tropic clima

Hi Sylvia

Chris here from the tropics of Queensland, Australia

Queensland runs from 10degrees south of the equator to 28degrees south of
the equator (it's a big place). Panama is 8 degrees north of the equator. So
I will compare you to the most northern costal area of Queensland. The
summers in the north are very wet with the monsoons, very high humidity and
high temperature and the occasional cyclone.

What you have to look at with SB is that the wetting potential which must
equal the drying potential of the wall. I tell people in the tropics to look
at their environment for the answer. If you are finding that through the
summer that mould and fungi is growing over your furnishings, curtains,
shoes, building etc (as it does) then it can be fair to say that it will
also grow in your SB walls. Remember also that rot will occur a lot faster
in a high humidity with high temperature then it will in a high humidity
with a low temperature.

So you need to consider how you can reduce your wetting potential during
your summer when the humidity is so high for so long that you have a very
poor drying potential. You will need very wide veranda, you may consider
using a cladding over your external walls (over the earth rendered SB wall).
Again look at your local environment for the answer. Are large verandas in
the local buildings enough to protect the traditional buildings from
moisture and rot. Also have a look at the historic buildings of the area,
are there other local, natural materials that are tolerant of this climate -
? sand bags. When in doubt start small - build yourself a shed and buy
yourself a moisture probe.

Regards Chris

Das ist ganz lieb.

Hello Dears,
we are a familie who go from germany to panama to live.
We want to live in a Strawbalehouse again, but we don`t know what is
different and what is really necessary to look for.
There they have "ricestraw" and much more insects than in germany. Who
can help us to talk about strawbalebuildings in tropic clima. We will be
very happy for answers.

Thank you
