Re: [strawbale] tipi cloth or plastic?

["Rene Dalmeijer" <rened@cistron...>]

Rikki,

I am afraid it is prone to rot and it will not function as a moisture
barrier. Canvas has to be wet before it becomes a water barrier and this is
condition you are trying to avoid.  Because the canvas is not out in the
open to dry rapidly it will be prone to rot due to slow drying. What you
need in this application is primarily a moisture barrier which dry canvas is
not. As you say yourself one of the positive aspects of cotton canvas is
that it is breathable when dry due to its large pores in its dry state it
will also allow water vapour through.

Greetings,
Rene

>I have a friend who make Tipis, and can get  me a great price on
impermeable, breathable cotton canvas.  Could I use this instead of plastic
or roofing felt as a barrier arounds posts, windows, on the roof, etc? or
should I worry about it rotting? He says that in tipi form (exposed to sun,
rain, hail . . .)it lasts about ten years, but if its not exposed it could
last a lot longer couldn't it? Has anyone tried something like that?
