Insulation in Chimney

My house has a chimney, really no more than a flue chase that is “kicked” out on the back side of the house. The flue for a zero clearance N.G. fireplace extends up the chase. Is it a good idea to insulate this area inside the chimney? With out any sheeting over the insulation, I worry about the insulation falling down on top of the fireplace. Is it code to insulate these areas? Would rigid foam be a better idea?

Codes tend to vary from area to area. Contact your local building inspector regarding codes in your area.

You can also contact the Chimney Safety Institute of America at their website at or email them <>

You can also consult with a local certified chimney specialist to have your chimney inspected and for advice.
