Hello Everyone,

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?

Awesome job!! How thick are your walls and what is your expected R-value? Also, whats the weather like there? I ask because I am planning on insulating an old home using strawbales, but havent decided on whether to use light Straw or full strawbales.
