What is a Chimney Liner?
The chimney liner is a barrier that lines the inside of the chimney.
It has three main functions:
- Protects the House from Heat.
Without a liner to serve as a refractive barrier, the high heat from the fireplace transfers from the chimney. This weakens and warps building materials and can lead to a fire!
- Protects the Masonry from Corrosion.
The byproducts of combustion can eat away at brick and mortar, allowing heat and smoke to escape into the home. Damage to the masonry can also cause structural damage to the chimney and home. The chimney liner is designed to withstand this type of chemical abuse. In addition, it will protect your chimney when installed properly and maintained regularly.
- Keeps the Air Moving.
What if the chimney is too tall to properly vent a certain appliance? A liner can be installed that properly funnels the smoke and carbon monoxide, without allowing it to come into the home. The shape, size, and length of the liner helps the airflow that vents the fire. To learn more about how the chimney works, click here. The draft and flow necessary to properly vent the fire can become inefficient and dangerous, without a properly sized and installed liner.
A Liner Problem
Over time the liner may become damaged. Also, an old liner (particularly clay tile liners) can become worn out and begin to chip away. You can detect a liner problem if you find pieces of clay tile in the fireplace – or if the surface of the chimney is excessively hot. When this occurs, a professional chimney sweep should be contacted to assess the problem. The best way to catch a liner problem before it affects your health or your home is to schedule routine sweeps and annual inspections. If a weakness, crack, or void in the liner is caught in time, it can be repaired easily, without needing to be replaced completely.
HeatShield® Cerfractory® Systems
Brickliners offers the best services to our customers in Northwestern Vermont. This means the best products! That’s why we repair liners with HeatShield® Cerfractory® Flue Sealant.
This trusted brand and product offers two modes of repair in which our technicians are experienced:
- HeatShield® Joint Repair.
This method, used for clay-liners with damaged mortar joints, is applied to fill gaps and then smoothed. This restores the smooth surface required for best airflow, safety, and efficiency.
- HeatShield® Resurfacing System.
For more extensive damage in which the liner might be replaced, this system resurfaces the existing liner, restoring it to full function. In this case, the flue liner is cleaned, gaps are filled, and then a primer is applied. Afterwards, a quarter-inch of HeatShield® is sprayed from top to bottom. This provides the same protection and durability as a stainless steel lining system!
