Where do I put insulation?

The most common locations for insulation are attics and exterior walls.  However, to gain the maximum impact and energy savings from your insulation, it should also be installed in ceilings with unheated spaces, overhangs, sun-rooms, etc.  Cellulose insulation can also be added to interior walls for increased sound proofing throughout the house. The diagram here shows the places that we recommend putting Cellulose insulation.
