I am currently retrofitting and old home to make it more environmentally friendly and energy efficient. And insulation is simply one of those things that needs to be done. I have access to bags and bags of polyiso foam insulation shavings and various sizes of foam off-cuttings that if not used will end up in the dump. I was wondering if anyone has any information on whether or not foam shavings can be used as a substitute for fiber glass blow-in insulation?
I have "heard" of folks using a Chipper /wood chipper to chip up foam remnants. then bagging it to use for insulating.
there might be somone on the web who has attempted this and shared it.
having used sheets of remnants from a SIPS panel factory to superinsulate my space, i know those tiny little beads
can statically cling to you and everything around you. The fellows who worked in the SIPS place all shaved their heads
to keep it from 'sticking in their hair'
