Flue Liner

Definition

A flue liner is a heat-resistant firebrick or other fire clay materials that make up the lining of a chimney.

Purpose

The primary purpose of a flue liner is to contain and safely expel the byproducts of combustion, such as smoke, gases, and unburned particles, from fireplaces, stoves, or furnaces. It serves as a barrier that protects the chimney walls from heat and corrosion, ensuring the structural integrity and safety of the building.

Examples of Use

• Installing a new chimney system for a fireplace often involves placing a flue liner to ensure safe operation and compliance with building codes.
• During chimney inspections, professionals check the condition of the flue liner to detect cracks or deterioration that might lead to hazardous conditions.

Related Terms

• Firebrick: A type of brick made to withstand high temperatures, used in lining fireplaces, kilns, and furnaces.
• Chimney Crown: The top element of a masonry chimney that helps protect it from weather damage.

Notes

Regular maintenance and inspection of flue liners are essential to ensure they remain intact and functional. Damaged liners can lead to inefficient operation and potential fire hazards.
