Re: Insulation ideas
- It is my understanding that "breathing" and "insulation" are pretty
much opposites. Insulation works by minimizing the scale of
convection currents in the air.
Something like ceramic microspheres would be good in that it would
not lose loft if it got damp, but it would also not be compressable.
Kind of like a high tech beanbag chair. :-)
Moisture in the insulation is inevitable, unless 1)there is enough
circulation or 2) the insulation is thin enough, either of which
would keep the dew point from occurring inside the insulation. Which
also means you would be cold.
Down and fibrous synthetics allow a certain amount of moisture to
continue to move through the insulation by diffusion even after the
moisture has begun to condense, which makes them less likely to feel
wet on your skin than a closed cell insulation.
