Chimney Liners — Cranford NJ.

A flue lining in a masonry chimney is defined as "A clay, ceramic, or metal liner.

The chimney is one of the most taken-for-granted parts of a home. Typically it tends to receive neither the attention nor the concern usually accorded other household service systems. The fact that chimneys may do their job reasonably well, even when abused or neglected, contributes to this atmosphere of indifference. Chimneys are far from the passive black holes that most people assume them to be. They perform several vital functions, and their simple appearance misrepresents their complex construction and performance requirements. A chimney deteriorated by constant exposure to the weather can be a potential safety hazard. Weather-damaged lining systems, flue obstructions and loose masonry materials all present a threat to residents. Regular chimney maintenance is essential to prevent damage, deterioration and future high-cost chimney repairs.

National Fire Protection Association | Cranford NJNational Fire Protection association states the following:
Damaged or deteriorated liners:
If the flue liner of a masonry chimney has been softened, cracked, or otherwise deteriorated such that it no longer has the continued ability to contain the products of combustion, i.e heat, moisture, creosote and flue gases, it shall be either removed and replaced, repaired, or relined with a listed liner system or other approved material that will resist corrosion, softening, or cracking from flue gases at temperature appropriate to the class of the chimney service.


The Problem

Most masonry chimneys were not designed to handle the venting requirements of modern high-efficiency heating appliances burning natural gas and oil. These improperly lined chimneys can cause a number of costly structural and cosmetic problems for the homeowner, and also create potentially serious safety hazards. Each year there are thousands of cases of Carbon Monoxide poisoning due to improperly lined chimneys

Stainless Steel Chimney Lining/ReLining
A Stainless Steel chimney liner is air and water tight. It locks in moisture and flue gases in your chimney and keeps them out of your home. This unique alloy is designed specifically to resist acids coming from gas appliances in the flue and extreme stresses of hot and cold cycles. Stainless Steel 316Ti liner has been UL Tested under the most extreme conditions including multiple simulated chimney fires exceeding 2100 F so you'll sleep soundly at night knowing that your home is safer for yourself and your family.

Liners in chimneys serve three main functions:

  • The liner protects the house from heat transfer to combustibles. In the NBS tests, unlined chimneys allowed heat to move through the chimney so rapidly that the adjacent woodwork caught fire in only 3 1/2 hours.
  • Liners protect the masonry from the corrosive byproducts of combustion. In the tests it was determined that if the flue gases were allowed to penetrate to the brick and mortar, the result would be a reduction in the usable life of the chimney. The flue gases are acidic in nature and literally eat away at the mortar joints from inside the chimney. As the mortar joints erode, heat transfers more rapidly to the nearby combustibles and dangerous gases such as carbon monoxide can leak into the living areas of the home.

    Liners provide a correctly sized flue for optimum efficiency of appliances. Modern wood stoves and gas or oil furnaces require a correctly sized flue to perform properly. The chimney is responsible for not only allowing the products of combustion a passage out of the house, but the draft generated by the chimney also supplies the combustion air to the appliance. An incorrectly sized liner can lead to excessive creosote buildup in woodburning stoves, and the production of carbon monoxide with conventional fuels.
