Since I only have 7-8" of blown in insulation in the attic I'm thinking this would be my next logical step to getting warmer temps in the rooms farthest from the stove. Moving air flow with fans aready in place but when temps dip under 10 degrees the temperature difference is greater than I would like. So, looking at the HD site they don't recommend rolls of insulation over blown in insulation. I would rather use rolls. Any insulation professionals care to respond?
