I was just told about Roxul insulation, to be used instead of fiberglass, and have just started reading about it. Apparently it's nearly the same cost, better R-value, and, less crap in the air/your lungs/skin when installing it, and much higher melting temp. It really seems like a superior alternative. Have any of you used it between studs, or between walls (stacked batt to batt)? If I can find it in Frb, I am seriously considering using it. I HATE installing fiberglass, and one post really slammed the efficacy of thicker fbrglass. Any experiences w/ Roxul? thanks. j
