Chimney Relines

Stainless Steel Chimney Liners

The perfect solution for an imperfect world!

The chimney liner is the ultimate solution to the problems that plague most chimneys. Modern stainless steel provides air tight and water tight barrier that seals in gases and creosote. Underwriters Laboratory declared that flex systems excel standards for chimney safety and can even withstand a chimney fire and still maintain structural integrity.

This system or its equivalent is to be installed in all new or existing masonry chimneys that are used for the natural draft venting of gas, liquid, and solid fuel fired residential type appliances and masonry fireplaces. While extreme care has been taken to make the system as safe as possible, proper installation, operation and maintenance should be followed.

What is a flexible chimney liner?

A flexible chimney liner is just that, flexible as opposed to rigid. The wall thickness ranges from .005 in. to .019 in. All stainless steel liners have some form of ribbed construction and are supplied in continuous lengths. Flexible liners allow for both top and bottom support because any expansion due to heating is absorbed by the liners flexible ribbing. Some flexible liners can be bent by hand while others are less flexible and require special tools for bending. The use of rain caps are required to maintain UL 1777 testing standards and protect your system.

Most liners offer a strong 7-ply seam which is air and water tight. The flex liner has corrugations between each reinforced seam offering greater flexibility. These unique alloys are designed specifically to resist acids in the flue and extreme stresses of hot and cold cycles.

Why do I need a Chimney Liner?

Here you can see after a mild chimney fire. Notice the very clean section where the fire occurred. At first look it doesn't appear as though there was any damage, however the only way to tell is to clean the entire system and inspect for cracks or missing tile. A more severe fire would have occurred if the fire started lower in the system, providing fuel the entire way out the flue. The owners of this residence were completely unaware this occurred. Many chimney fires are small and undramatic, causing damage with no obvious proof it occurred until inspected.

This is an older chimney constructed before flue tiles were part of the assembly. After years of weather and the acidic effects of creosote mixed with water, many have deteriorated mortar joints between the bricks. This poses a large risk in the event of a chimney fire with the fire spreading into concealed spaces such as attics, walls and floors. If venting a gas appliance, carbon monoxide is able to leak into the home undetected, causing illness and other health issues. This is extremely common during cold months due to animals building nests inside because of the warmth coming up the flue, and should be relined with the appropriate liner and have an animal guard or spark arrestor installed at the top.

Insulation is Not Optional

Chimney liners are not tested without insulation and do not have a UL listing when installed incorrectly. Many companies will provide you with an option on insulation, or not offer it at all. This keeps costs down and profits high but puts your home, property and life at risk. Only accept the UL listed and approved installation requirements on your home.

Two additional reasons to insulate:

1. Under extremely hot flue conditions, insulation keeps the high temperature from spreading through the masonry chimney to combustibles, including those with low ignition temperatures (chase surrounds, attic rafters, walls and floors).
2. Insulation keeps flue gases warm, stabilizing draft for peak efficiency and minimizing creosote and condensation problems. As smoke cools, it gets sticky. The warmer your flue stays during use, the less creosote will remain in the system.

We provide two separate types of insulation for use with stainless steel liners. The first is a vermiculite and concrete insulation mixture that is poured down the chimney and dries in place. This pour down mixture is an easy answer to reducing condensation and stabilizing your draft. It is also the best insulating solution for those tight clearance chimneys.
