HeatShield®: Repairing Your Chimney Clay Liner

HeatShield® is a specially formulated “Cerfractory®” material that restores the integrity of your chimney’s flue to vent hazardous flue gases from your home. This method of repair has been used in Europe for over 20 years and is gaining popularity in the United States because the repairs can be done without removing the terra cotta clay tiles that currently line your flue.

The Mess of Clay Tile Removal

Relining your fireplace flue with stainless steel requires the removal of the existing terracotta clay tiles, and this is a destructive process. Your chimney was not designed to be taken apart and then reconstructed, although at times it is necessary.  The process is both time consuming and can be incredibly messy from the tile removal process.

We have found, if given the choice, more homeowners are choosing HeatShield® to repair their flue. It is simply because it takes half the time and does not impact the chimney structure by the tile removal process and does not potentially cause a mess.
