When and Why should I Insulate?

Interior chimney location. Your chimney is not on an outside wall

The masonary chimney linning is cracked or missing.

A great reason to always use Insulation:  Insulation keeps flue gases warm, stabilizing draft for peak eficiency, and minimizing creasote and condensation problems.
