Lining your chimney with the right types of chimney liners is important to protect the air going in and out of your chimney flue, and prevent heat damage and corrosion. Building codes will vary by state, country, and region, as most inspectors will want to ensure that enough lining is present to prevent any major structural damage. Most chimney liners are made of clay, ceramic, or metal combinations that are installed alongside the inside walls of the chimney chute. These serve as a protective barrier against weathering and general deterioration, and can also help improve the air circulation throughout your fireplace and chimney vents. Most fire codes now require a liner as part of the construction process.

There are many dangers to unlined or broken chimneys, and it is essential that you install an appropriate chimney liner to protect the home and surrounding area. Chimney liners are especially important for larger homes, and those that use the fireplace frequently.

Chimney liners are important for a variety of reasons. First, they can help protect the house and home from combustible material, as the heat can move very quickly throughout the chimney chute and cause damage to the surrounding woodwork. A chimney liner can control and maintain a steady temperature in the area. Chimney liners also protect the masonry of the chimney chute, helping extend the life of the chimney. If mortar joints are eroding, heat can become dangerously combustible and even leak carbon dioxide into the home. Finally, chimney liners can help to optimize the efficiency of your fireplace unit. Since the chimney is responsible for managing the distribution of energy, it can allocate just the right amount of heat upward so that combustion does not take place anywhere near the fireplace.

Clay tiles are the most common types of chimney liners, and these are fairly inexpensive to install. Since ceramic does not rapidly distribute or absorb heat, it can be disadvantageous to larger houses. In addition, it has a high breakability rate because of its delicate construction. It may crack or break easily, and can become cumbersome to replace.

Metal chimney liners are commonly made of stainless steel or aluminum, and can be used as a repair material for cracked or broken chimneys. If the entire liner is made of these materials, it can help make the heat and energy supply very efficient. Cast-in-place chimney liners are lightweight, and can provide a smooth and seamless flow of air. It is a cost-effective way and simple method to install a chimney liner.
