HeatShield FAQs - Nashville TN - Ashbusters Chimney

Why would I need to use HeatShield on my chimney?

According to the Chimney Safety Institute of America (CSIA), cracks, gaps, and spalling in your clay chimney flue and/or in the bricks and mortar of your chimney itself can pose serious risks to your health and the health of your family as well as your home. If your flue liner is damaged, your chimney cannot correctly or efficiently perform its main job of containing and venting away the toxic by-products of combustion.

How exactly does HeatShield restore my chimney flue liner?

Consisting of specially formulated “Cerfractory” sealant material that restores the integrity of your chimney’s clay flue liner to vent toxic gases from the house, HeatShield uses two different chimney flue liner repair methods as well as a CeCure Sleeve Relining System. Which method our Ashbusters technician will use depends on the condition of your clay flue liner. HeatShield is guaranteed to eliminate the dangers in your chimney caused by gaps, cracks, and spalling for years to come.

What are the two different HeatShield chimney flue liner repair methods?

The first, the Joint Repair System, is for liners that are only in need of repair of deteriorated mortar joints. During this method, a customized-to-your-chimney foam applicator and blade are inserted into your chimney and positioned below all gaps and voids. The HeatShield Cerfractory Flue Sealant mixture is then added to fill every gap and void in your flue. After each gap or void is repaired, the blade comes across it to smoothen it out. The second method, the Resurfacing System, is for cracked or spalled yet otherwise still sound flues and works by applying a coating of HeatShield Cerfractory Flue Sealant to the entire chimney flue. Both of these repair methods are scanned upon completion by video for verification of proper application.

What is the CeCure Sleeve Relining System?

If a chimney has serious damage or has no liner at all, the CeCure Sleeve Relining System, a thin profile, ceramic insulation which is reinforced with stainless steel fabric and sandwiched between two layers of HeatShield Cerfractory Flue Sealant, is used to reline the chimney. Your newly lined chimney will be video scanned to ensure it has been properly installed.

What exactly does “Cerfractory” mean?

According to the HeatShield company, the term is a combination of “ceramic” and “refractory.” These were the two types of coatings used in creating the HeatShield mixture when it was developed in Europe over 20 years ago.

Do technicians have to go through specialized training to apply HeatShield repair methods?

Yes, and not only do technicians have to be trained by the HeatShield factory, but the HeatShield company only selects independent companies like Ashbusters to be authorized users of HeatShield, based on industry certifications and experience.
