Can I add Roxul RockFill behind finished wall?
I have a finished condo with columns around the perimeter surrounded by drywall. Those columns are currently filled with a small amount of pink insulation. I can detect air currents coming out of some of the outlets on the columns. I was wondering if tightly packing Roxul Rockfill (http://diywithroxul.com/en-us/rockfill.html) along the base of these columns behind the drywall via the electrical outlets would negatively affect anything, given that I’d only be putting the insulation at the base and it would be mixed with the existing pink insulation.
