HeatShield Flue Repair

The purpose of  your chimney is to safely convey the products of combustion outside of your home to the outside atmosphere. When masonry flue liners are misaligned, cracked or otherwise damaged so that they can no longer perform they’re intended function they must be removed and replaced, repaired or relined. A defective chimney flue can leak flue gases containing carbon monoxide in to the home or allow heat to come into contact with concealed combustible framing. This is an extremely dangerous situation and can lead to a structure fire. HeatShield Flue Repair can completely seal these types of defects.

Do you have a masonry chimney with cracked flue liners? Resurfacing with the HeatShield Chimney Liner Repair and Resurfacing System restores your masonry flue liners to better than new condition. HeatShield Flue Repair restores the integrity of your masonry chimney’s flue to vent hazardous flue gases from your home by completely resurfacing the flue and sealing all gaps, cracks, spalling and/or other defects. Armour Chimney Service is a factory trained HeatShield Flue Repair installer.

HeatShield® is a specially formulated “Cerfractory®” sealant material that restores the integrity of your chimney’s flue to vent hazardous flue gases from your home.

By using either the Repair System or the CeCure® Sleeve Relining System (depending on the defects found) your chimney will be restored to its original peak level of safety and efficiency.

HeatShield’s hybrid “Cerfractory” technology combines the strength of a high-fired ceramic with the heat resistance of high temperature refractory cements.

HeatShield has been tested to ASTM C199 Standard Pier Test for Refractory Mortars and is rated “Super-Duty”. It exceeds both IRC and NFPA code requirements, which specify medium-duty.
