Types of Reliners

Clay Tile

Are the most common type of masonry chimney liners
Inexpensive, readily available and used mainly in new masonry chimney and fireplace construction

Functionality of Clay Tile

Clay tiles are of a ceramic material, cannot rapidly absorb and evenly distribute heat during a rapid temperature rise that occurs during a chimney fire. This uneven heating produces an unequal expansion which in turn causes the flue tiles to crack and split apart . This is similar to immersing a cold drinking glass in very hot water.

A chimney with cracked chimney liners must be replaced and repaired before using again. Also the tiles cannot adequately contain the liquid combustion byproducts produced by modern wood and gas appliances. Click here for best method of repair.

Stainless Steel is a metal liner that is either flexible or rigid, comes in many shapes; oval square, round or rectangular. Click for Photo Description.
These liners are used mainly for wood stoves or wood furnaces. Are UL tested and listed.

Functionality of Stainless Steel

Installed inside masonry chimneys mainly to upgrade the existing chimneys.
Used for coal, wood, gas or oil. Must use a specific type stainless steel liner that is specifically tested for the fuel being used in the appliance.
Example: when wood fuel is used, the liner must be tested for wood fuel usage, cannot use a stainless steel liner tested for gas in a wood fired appliance. In other words cannot use a stainless steel liner for any type of fuel, except for the fuel that it was specifically tested and listed for.
Limited for only one type of usage.
Is put together in various length sections by screws or rivets.
Required that high temperature insulation be used in conjunction with the liners for safety and performance considerations.

Aluminum is a metal liner that is either flexible or rigid. Is round in shape. Are UL tested and listed. Click for Photo description.

Functionality of Aluminum

Is similar to stainless steel except can only be used to vent certain types of gas appliances.
Gas logs intended for installation in wood burning fireplaces may not be vented with Aluminum liners.

Cast-in-place chimney liners are made of a lightweight, castable, powdered volcanic rock and cement material that is installed inside the chimney forming a smooth, seamless, insulated passageway for the flue gasses. Click here for Photo description.

Functionality of Cast-In-Place

This method involves placing round or oval bladders ( inflatable rubber form) inside the existing chimney flue then pouring (casting) the masonry material around the inflated former.
After the masonry material hardens then the inflatable former is deflated and pulled out of the chimney leaving a smooth, seamless, one continuous liner from bottom to top of chimney.
The cast masonry material is pumped into the chimney in a wet soupy condition, this allows the material to flow into the various cracks and areas where mortar is missing, filling all these areas with the cast masonry material.
The cast masonry material bonds to all four walls becoming interconnected with the entire chimney structure, thus strengthening the chimney structure and adding many useful years of life to the chimney. Click here for UL Listing and Warnock Hersey.
This type of liner actually repairs deteriorated and flue fire damaged chimneys .
This type of liner is a permanent repair solution .
This type of liner is designed to be used for all types of fuel.
