Re: GBlist: Strawbale not good for humid, mixed heating andcooling climates -Reply2x


Thanks for your reply. Regarding what I believe:
1) Straw bale construction can make as much sense in mixed climates as
2) Coming from a builder-owner, time-honored tradition of cut and shim
technology, I ASSUME the skin will inevitably leak--hence my damage-control
hedge of the overhang. My advice is give the outer skin and the flashing
your best shot, but don't bet the house on it. Don't tempt the fates. Use a
generous overhang and keep the water off the walls to begin with.

Generous overhangs make even more sense in a southern climate like the
North Carolina case in point where we spend more money on cooling than on
heating, whether its because of heating/cooling degree days, or because the
cost of cooling fuels (electricity) are higher than heating costs (gas,
wood, passive solar, sawdust, etc.). Plus, generous overhangs cry out to
cover a porch which keeps you out of the grass which is where chiggers lie
in wait.

But I digress.

Yes, a straw bale system that includes something that equates to the
"building paper drainage plane to deal with water" you suggested makes

You wrote: "Ron: the question is whether you believe you can build a "skin"
that will
never leak. Traditional stucco assumes there will be leaks whether there
is proper flashing or not, and utilizes a building paper drainage plane to
deal with the water that they know will eventually get in. Presumably,
straw bale builders could do something similar, although I've never seen
those details".
