Understanding the Different Types of Chimney Liners

In order for your chimney and fireplace system to work at its highest levels of safety and efficiency, all of its components need to be in good condition. One of these components, the chimney liner, has three important functions. It protects your home from high heat transfer, it keeps the bricks and mortar joints protected from the corrosive gases of combustion, and it provides a properly matched flue with your hearth heating appliance. For over 25 years, All Seasons Chimney has provided superior professional chimney maintenance, repair, and installation services, including Different Types of Chimney Liners - Poughkeepsie NY - All Seasons Chimney chimney relining, to the lower Hudson Valley area. We would like to tell you more about the three different types of chimney liners and their advantages and disadvantages.

CLAY TILE

If you have an older home with a masonry chimney, you likely have a clay tile liner. According to the Chimney Safety Institute of America (CSIA), this is the most common type of chimney liner. Inexpensive and durable, clay tile liners perform very well when you regularly maintain your chimney. Following a routine chimney maintenance schedule can prolong the life of a clay tile liner; however, years of exposure to extremely high temperatures causes the tiles to crack and crumble. Fortunately, All Seasons Chimney can repair and restore the liner with our HeatShield services.

METAL

Whenever All Seasons Chimney updates fireplaces with new inserts, we usually install a new stainless steel chimney liner as well to provide a flue that matches the size of the new fireplace insert. Metal chimney liners are extremely durable and are safe to use with every fuel type. The only disadvantage of this type of liner is that it is considerably more expensive than the other types of liners; however, stainless steel chimney liners are typically guaranteed for a lifetime.

CAST-IN-PLACE

This type of chimney liner is a lightweight cement-like product that is poured into the chimney to form a seamless and smooth flue as it dries. Cast-in-place liners provide excellent insulation and can boost the stability and integrity of the chimney structure. Since this type of liner can be a challenge to install, the labor costs can be higher than average.

All About HeatShield

If you have an older home with a masonry chimney, you most likely have a clay tile chimney liner. The liner was constructed at the same time as your chimney. Despite long term durability, it can suffer from damage over the years including chipped and cracked tiles. Over time, the tiles will fall from the walls of the chimney, and the gaps left behind can lead to hazardous situations, like chimney fires and carbon monoxide leaks. The problem with a damaged clay tile liner is that it is very expensive to repair because it is labor intensive and time-consuming. Fortunately, there is another option for restoring a clay tile chimney liner – HeatShield. All Seasons Chimney is an authorized HeatShield dealer in the Hudson Valley. We would like to take this chance to tell you more about HeatShield.

What exactly is HeatShield?

All About HeatShield - Poughkeepsie, NY - All Seasons ChimneyKnown as Cerfractory technology, HeatShield is a hybrid of ceramic and refractory coating used to line chimneys and flues. It withstands moisture, and corrosive combustion gases, as well as temperatures exceeding 2900 degrees Fahrenheit. Developed over 20 years ago in Europe, HeatShield can restore your chimney to its original peak of safety and efficiency.

How can HeatShield restore the integrity of my chimney?

Depending on the chimney’s damage, All Seasons Chimney will determine exactly which method of HeatShield is the best to use. We will use the Joint Repair System if your liner only has a problem with defective mortar joints. In addition, if there are defective joints and other minor problems with the clay tile liner, we will use the Resurfacing System to restore the liner. With both systems, we apply the HeatShield formula using a special foam applicator custom made to fit your chimney. This unique application process is “slip casting.”

What if my clay tile liner has major damage?

If your clay tile liner has serious damage or if your chimney is unlined, Ace Chimney Sweeps can use the CeCure Sleeve Relining System with the HeatShield formula to make your chimney safe and efficient again. This system involves ceramic insulation reinforced with stainless steel fabric and then sandwiched between two layers of HeatShield formula.
