Insulation Behind the Fireplace

A few weeks ago, we realized there was a HUGE draft coming from the molding by the side of the fireplace.  When we removed the molding, there is a really big gap, and cold air from the garage is definitely coming into the family room.  Paul went and bought a huge roll of insulation and stuffed it in to try to fill in the gap.  Seems better now.  Too bad we didn't realize all winter long!
