We had all of our old home-insulation removed and replaced with upgraded products last month. Converted from rolled Fiberglass: (the pink stuff) Low r-value, poor air quality, Formaldehyde off-gassing. Went with blown-in Cellulose: Higher r-value, fills hard to access areas, covers non-uniform surfaces. No air quality issues. We did this for health reasons, old, mold, dust, dirt, bird-poop etc. Of course, the installer promised improvements in home efficiency and reduced power consumption.....but my honest expectations, here, were pretty low..... Just got my 1st power bill after conversion. 6/21-7/20, 2013 = $1,558 6/21-7/20, 2014 = $ 439 Guess he was right.....eh?
