Rigid vs Flexible Chimney Liner


When it comes to ensuring the safety and efficiency of your chimney, selecting the right type of liner is crucial. Chimney liners serve to protect your home from heat transfer and prevent the accumulation of hazardous gases. Among the options available, stainless steel liners stand out for their durability and effectiveness. However, within this category, you must choose between rigid and flexible liners. This article will delve into the differences between rigid and flexible chimney liners, helping you make an informed decision based on your specific needs.

Understanding Rigid Chimney Liners

Rigid chimney liners are made from solid, straight sections of stainless steel and are best suited for chimneys with a straight path without any offsets or significant bends.


Durability: Rigid liners are incredibly durable and resistant to corrosion and heat, making them ideal for wood-burning appliances.
Efficiency: They offer a smooth interior surface that improves airflow and draft, enhancing the efficiency of your heating appliance.
Longevity: With proper maintenance, rigid liners can last for decades, providing a long-term solution for your chimney.

Installation Challenges: Rigid liners can be difficult to install in chimneys with bends or offsets. The installation process may require more extensive modifications to the chimney structure.
Cost: Due to their durability and material quality, rigid liners can be more expensive upfront than their flexible counterparts.

Understanding Flexible Chimney Liners

Flexible chimney liners, on the other hand, are made from corrugated stainless steel that can bend and adjust to the contours of your chimney. This flexibility makes them suitable for chimneys with bends, offsets, or irregular shapes.


Versatility: Flexible liners can be maneuvered through complex chimney structures, making them ideal for retrofitting older chimneys that do not have a straight path.
Ease of Installation: The flexibility of these liners significantly simplifies the installation process, often resulting in lower labor costs.
Adaptability: They can accommodate the expansion and contraction caused by temperature changes, reducing the risk of damage over time.

Maintenance: The corrugated interior surface can accumulate creosote and soot more easily than the smooth surface of rigid liners, potentially requiring more frequent cleaning.
Durability: While still highly durable, flexible liners may not last as long as rigid liners in certain conditions, especially when used with high-temperature appliances like wood stoves.

Choosing Between Rigid and Flexible Liners

The choice between rigid and flexible chimney liners depends on several factors:

Chimney Structure: If your chimney is straight without any offsets, a rigid liner may be the best option. For chimneys with bends or irregular shapes, a flexible liner will be necessary.
Type of Appliance: Wood-burning appliances that produce high temperatures and corrosive by-products may benefit more from the durability of rigid liners. Flexible liners, however, can be a good choice for gas or oil appliances.
Installation Considerations: If ease of installation and lower initial costs are priorities, flexible liners offer advantages. For those focusing on long-term durability and performance, rigid liners may be preferable.


Both rigid and flexible chimney liners have their place in maintaining the safety and efficiency of your chimney system. Your specific situation—considering your chimney’s architecture, the type of fuel you use, and your budget—will determine the best option for you. Regardless of your choice, ensuring that your chimney liner is correctly installed and regularly maintained is key to protecting your home and ensuring the efficient operation of your heating appliance.

Why Choose Stainless Steel Chimney Liner

Chimney Liner Coils

Choosing the right material for your chimney liner is crucial for the safety, efficiency, and longevity of your chimney system. Among the various options available, stainless steel stands out as the premier choice for homeowners and professionals alike. This article explores the compelling reasons why a stainless steel chimney liner is often the best option for your home.

Durability and Longevity

One of the most significant advantages of stainless steel chimney liners is their exceptional durability. Stainless steel is highly resistant to corrosion and rust, which are common issues with other materials exposed to the harsh conditions inside a chimney. This resistance ensures that your stainless steel liner can withstand the acidic by-products of combustion, moisture, and extreme temperatures without deteriorating over time. As a result, stainless steel liners often come with longer warranties, some extending for the lifetime of the liner, providing peace of mind and reducing long-term costs.

Improved Safety

Safety is a paramount concern when it comes to chimney operation. Stainless steel chimney liners provide a secure conduit for harmful gases produced during combustion to exit your home. Their robust construction minimizes the risk of cracks and gaps that can occur in older clay tile liners, significantly reducing the likelihood of carbon monoxide leakage or chimney fires. By maintaining a consistent flue size and smooth surface, stainless steel liners also improve draft, further enhancing the safe operation of your fireplace or stove.


Stainless steel liners are suitable for all types of fuels, including wood, gas, oil, and coal. This versatility makes them an ideal choice for any heating appliance, whether you are installing a new system or upgrading an existing one. Additionally, stainless steel liners can be fitted into any chimney, regardless of its shape or size, thanks to flexible and rigid options. This adaptability ensures that homeowners can benefit from the advantages of a stainless steel liner, no matter their specific requirements.

Energy Efficiency

Installing a stainless steel chimney liner can enhance the energy efficiency of your heating system. The smooth interior surface of stainless steel improves airflow and reduces the buildup of creosote, ensuring that your fireplace or stove operates more efficiently. This can help in reducing fuel consumption and lowering heating costs. Furthermore, the tight seal formed by a properly installed stainless steel liner prevents heat loss, keeping your home warmer during the colder months.

Ease of Maintenance

The maintenance of a chimney liner is critical for its performance and safety. Stainless steel liners are easier to clean compared to other materials, as their smooth surface allows for the efficient removal of soot and creosote. This ease of maintenance not only simplifies the cleaning process but also contributes to the overall safety and efficiency of your chimney system.


Choosing a stainless steel chimney liner offers numerous benefits, including durability, safety, versatility, energy efficiency, and ease of maintenance. These advantages make stainless steel an ideal material for homeowners seeking to enhance the performance and safety of their chimney systems. With its long-term value and proven performance, a stainless steel chimney liner is an investment in the safety and comfort of your home.

The Essential Guide to Chimney Top Plates: Ensuring Safety and Efficiency


A well-functioning chimney is crucial for maintaining the safety and efficiency of any fireplace or wood-burning stove. Among the various components that make up a chimney system, the chimney top plate plays a significant role in protecting your home from external elements while allowing for proper ventilation. In this article, we will explore the importance of a chimney top plate, its functions, and why investing in a high-quality product is essential. If you’re looking to enhance your chimney’s performance, read on!

Understanding the Chimney Top Plate:

The chimney top plate, also known as a chimney cap or chimney crown, is a protective covering that sits at the topmost part of a chimney. It serves as a barrier against rain, snow, debris, and animals, preventing them from entering the chimney and causing potential damage. Furthermore, a well-designed chimney top plate also facilitates proper airflow, preventing downdrafts and ensuring efficient ventilation.

Functions and Benefits:

Weather Protection: The primary purpose of a chimney top plate is to shield your chimney from the elements. Rainwater and melting snow can cause significant damage to the interior of your chimney, leading to costly repair. By installing a top plate, you can prevent water entry, preserving the structural integrity of your chimney and avoiding potential leaks.

Debris and Animal Prevention: Leaves, twigs, and other debris can find their way into an unprotected chimney, creating blockages and reducing airflow. Additionally, birds, squirrels, and other small animals may attempt to build nests in chimneys, posing a fire hazard. A chimney top plate acts as a barrier, preventing debris and animals from entering your chimney, ensuring a clear and safe passage for smoke and gases.

Increased Ventilation Efficiency: Proper ventilation is crucial for maintaining optimal performance and preventing harmful gases, such as carbon monoxide, from accumulating in your home. A well-designed chimney top plate helps create a balanced airflow, reducing the likelihood of downdrafts and improving overall ventilation efficiency.

Invest in Quality:

When it comes to chimney top plates, investing in a high-quality product is of utmost importance. Opting for a durable and well-constructed chimney top plate ensures long-lasting protection for your chimney and reduces the need for frequent replacements or repair.

At Chimney Liner Depot, we take pride in manufacturing top-quality chimney top plates that guarantee superior performance and longevity.

Why insulate your stainless steel chimney liner?


Basically you need insulation for safety and performance.  The safety issue is a no brainer.  Keep the extremely high temperatures that can reach 2100 degrees away from your home and prevent a house fire.

The second reason, performance, is a more difficult one to understand for some.  Here is a picture of a cap from a customer who did not use insulation around the stainless steel chimney liner.  The smoke cools down too much and creates creosote.  The screen was almost completely blocked on this rain cap.

“Last Thursday, 9/12/13, I ordered a chimney liner kit from you. I ordered a 6’X20′ Flex King liner kit with cap, tee, liner and top plate. On Friday 9/13 I received a tracking email and by the time I got home from work it was there!

I recently hurt my shoulder in an accident and am one arm down. I enlisted the help of my father to do the install. After getting the parts laid out and prepping the work area, my dad and my disabled self had the whole liner installed and ready to go within 2 hours!

I really appreciate your professional service and complete kits. I researched these liners for 2 years before I made this purchase and just wanted to say thanks and you are appreciated.”

Why buy a Chimney Liner now?


Why should you buy a chimney liner now?  Some people think they will now wait until spring to install a chimney liner.  There are multiple reasons to install a chimney liner now and not wait.

First, it can be very dangerous to wait.  The chimney may appear to be in good condition on the outside but the inside could be a different story.  Chimneys deteriorate from the inside out.  So even though the outside looks good the inside, the flues, could be cracked and allowing poisonous gasses into your home.

Second, prices are going up.  As you can see, we are the cheapest online because we are the manufacture of the chimney liner.  But our prices will increase soon.  So buy now to save money and keep your family safe.

Gas Boiler Chimney Flue Liner


If you are installing a gas boiler you most likely will need a chimney liner. If you don’t need one now, you will need one soon. A gas boiler vents a lot of condensation and acid residue into a clay flue liner. This type of venting is very damaging to a masonry chimney. The best way to protect your masonry chimney is to install a stainless steel chimney liner.

A stainless steel chimney liner is guaranteed to last forever. Save yourself lots of money and labor by installing a stainless steel liner at the time of the gas boiler installation.

Give us a call at 1-866-941-5112 and we will help you determine the proper size chimney liner for your chimney.

Chimney Liner Types


When relining a chimney there are several types of chimney lining systems available. Chimney Liner Depot carries flexible and rigid chimney liners.

A rigid chimney liner is hands down the best chimney liner available. It’s glass smooth interior promotes excellent chimney draft and makes it harder for creosote to stick to than traditional liners. The only problem with rigid chimney liners is that it is not always a chimney lining system that will fit in a chimney. In order for a rigid chimney liner to fit in a chimney, the flue must be perfectly straight.

If your chimney flue is not straight a flexible chimney liner is what you will need to install. Chimney Liner Depot carries several lines of flexible chimney liner. Give us a call today to discuss your chimney relining requirements and we will help you figure out the best solution.

    *Note: If you have a terra cotta clay chimney
    flue lining, be sure to measure the true length and width of the
    inside of your chimney flue space.

    *If there is a terra cotta clay flue liner, does it protrude out of
    the top of the chimney at least 2 inches? If there are at least 2
    inches and the terra cotta clay is in good condition, you will use
    our stainless steel, terra cotta top plate that has a 1 1⁄2inch edge
    that goes all the way around (like a shoebox lid).

    *If your terra cotta clay flue is in bad shape at the top, you may
    need to just take a hammer and tap all around that terra cotta,
    taking it away to make the surface flat at the top of your chimney.
    In that case, you will simply use the flat top plate that comes with
    our liner kit.

    *Note: If you have a terra cotta clay chimney
    flue lining, be sure to measure the true length and width of the
    inside of your chimney flue space.

    *If it is on the back of the stove, is it parallel with the back of the stove or is it at an angle, like 45 degrees?

    *If it is at an angle you will use an insert stove adaptor (an insert liner kit) rather than a two-part tee with cleanout cap.

    Usually pellet stoves have an exhaust hole id of 3 inches. However, if you are going up more than 15 feet to the top of your chimney you need to use a pipe and/or flex liner that is 4 inches diameter.

    If you are only venting a hot water heater then the exhaust hole diameter is probably 3 inch diameter. If it is 3 inch diameter and you are going up more than 15 feet to the top of your chimney, you must use a 4 inch diameter flexible liner or ridged pipe for proper draft. We also suggest to go ahead and use a 4 inch diameter flexible liner or ridged pipe even if the total length is 15 feet or less.

    Not the depth or any other dimension inside your fireplace.

    Most gas log fireplaces require an 8 inch liner kit or rigid kit. But do not assume that is the case for the gas log fireplace kit you are installing. Obey the requirements for that specific unit that are in your installation/instruction manual.
