PC as insulation........ I have mentioned wet spray cellulose a number
of times. It mats in quite firmly..... it isn't "stiff or rigid", but
it sticks into the wall and you have to tear it out... without even
using the stabilized version. The installation method is an ordinary
insulation blower and a small pump.. like a pressure washer pump feeding
a couple of spray nozzles. The insulation blowing nozzle is a flattened
tube, and the spray nozzles are aimed upward slightly so they intersect
the stream of dry cellulose and dampen it. The material is sprayed at a
moisture level such that you cannot wring water out, but it will dampen
your hand a bit when you squeeze it.
This is a fast efficient and simple system with good results and high R
value.... far less trouble than making slurry and trying to make rigid
insulation board out of it.
