What Is HeatShield — And Can I Benefit From It?

Back in the early days of manned space flights, the most tense moments What is HeatShield- And Can I Benefit From It- Fort Wayne, In- Old Smokey's Fireplace & Chimney-w800-h597occurred during reentry. (And it’s still the case.) As the world awaited word of a safe landing, the chief concern was: Is the space capsule’s heat shield intact? Without a properly working heat shield, the flight would end in a fiery disaster. When it comes to your home and its chimney, what’s the role of a heat shield?

Although the circumstances are less dramatic and dire than space travel, your home may be a good candidate for HeatShield. HeatShield is a masonry flue lining sealant that protects and restores the workmanship of your chimney system. As with the heat shield that protects astronauts and cosmonauts, it helps performance and prevents potential disaster.

Devised by Cecure Chimney Systems, HeatShield uses a specially formulated sealant to restore the integrity of your chimney’s flue. Applying this sealant corrects fissures caused by gaps, cracks, or masonry spalling. This consequently allows your chimney to properly vent hazardous gases. When Old Smokey’s technicians apply the HeatShield sealant to your flue lining, we aim to restore your chimney to its optimum level of safety and efficiency.

What is the best way to know if your chimney needs a new liner or any other repair? Sign up with Old Smokey’s to get a professional inspection. A careful inspection by a qualified professional is a common-sense way to start. Instead of relying on guesswork or possibly erroneous conclusions, rely on Old Smokey’s pros to discern if you have hidden dangers lurking within your chimney or any of its interior parts.

With an Old Smokey’s professional chimney inspection, we can evaluate the condition of your flue, the chimney lining, the bricks and masonry, and the flashing and sealant.

What is Involved in Chimney Relining?

Chimney Relining Flue Repair - Fort Wayne IN - Old Smokey'sIf, at any time, your chimney professional tells you that you need a new liner or that you need to repair the existing one, please don’t put it off. Every chimney needs a working liner to usher deadly carbon monoxide gases from your home. If your current liner was installed improperly or if it is deteriorating, it is highly recommended that you have a new one installed by a licensed professional, as a damaged liner can allow poisonous carbon monoxide gases and smoke to enter your home. Depending on the type of chimney you have, there are several different relining options that may be presented to you.


The majority of older homes have chimneys with liners made of clay or clay tiles; it is commonplace to repair or replace them with new clay liners, although switching over to a stainless steel chimney liner is an available option. Clay tiles can withstand extremely high temperatures without damaging or hindering the performance of the liner itself; they also hold up quite well against the corrosive materials that are burned in and pass through the system.


Heatshield Resurfacing and Relining - Fort Wayne IN - Old Smokey'sAs chimney liners go, Heatshield Relining System®  option offers the highest levels of safety, thermal efficiency, and longevity of any liner available. Cast-in-place liners are installed by pumping a concrete-like material around a former, which is inserted down the full length of the chimney. After the lining sets, the former is removed, giving you a smooth, seamless, and extremely well insulated chimney liner. This type is ideal for applications in deteriorated chimneys that need structural support. They are rated to withstand a higher temperature than either the clay or stainless steel liners.


The vast majority of newer homes have chimneys with stainless steel chimney liners already installed. These liners come in two different forms: rigid and flexible. The type your technician will choose ultimately depends on the shape of your chimney. A huge selling point for stainless steel liners, in general, is that it comes with a lifetime warranty. They resist rust and easily hold and move heat and smoke up through the house and out into the atmosphere. If properly installed and maintained, stainless steel liners are extremely safe and durable. It is usually recommended that high temperature insulation be used in conjunction with the liners for safety and performance considerations.

Although building codes vary from one locality to another, the installation of flue liners has been recommended for many years now, and indeed most fire codes now mandate liners. There are many reasons you may need to reline your chimney. Whatever the case may be, you have several options available to you. The CSIA-certified technicians at Old Smokey’s Fireplace & Chimney will be there with you throughout the decision making process to help you determine which relining option best meets your needs and the needs of your family.
