Damaged chimney liner? HeatShield® can restore your chimney’s clay flue liner and save you the expense of rebuilding or relining with a stainless steel chimney liner.

A thorough inspection of your chimney liner may reveal hidden dangers. To choose an effective, economical solution you should know how your chimney works, and understand the fire & health risks these dangers can cause.

HeatShield’s Cerfractory technology is a hybrid (ceramic/refractory) coating that was developed in Europe over 30 years ago. HeatShield restores the integrity of your chimney’s flue to vent hazardous gasses from your home. It eliminates the dangers in your chimney caused by gaps, cracks, and spalling for years to come.

HeatShield is an eco-friendly product made from recycled and naturally occurring materials. It offers you a less costly alternative to rebuilding your chimney or the destructive removal of flue tiles before the chimney can be relined.
