    I installed my Hearthstone Clydesdale w/ 1/2" liner insulation, Roxul at top of chimney and at bottom with a sheet metal block off plate. Can I add it to the sides of the opening where the cover plate surround is?

    Averill Park, NY, on Burden Lake II...
    You shouldn't need to insulate there if you have the block-off plate. Any gaps where the surround meets your fire place facing material will allow additional heat into the room...
