Chimney Stainless Steel Liners

The Problem: Dangerous Chimneys

House With Chimney

Home Safety

Your chimney has a big responsibility. It carries toxic gas out of your home, and while doing its job, it must withstand constant attack by acid, creosote, and extreme temperatures for years on end.

These conditions cause chimney damage and deterioration, and when that happens, your family's safety is in question.

With the real risks of carbon monoxide poisoning and chimney fires becoming house fires, venting is a serious responsibility.

Outside vs. Inside

Look at the picture on the left. Most people would not see anything wrong with this chimney. But there is more to the story. On the inside, the chimney could be seriously damaged and not be up to safety regulations.

Old vs. New

Old-fashioned chimneys were not designed to vent modern heating appliances. Besides, no chimney lasts forever.

Furnace Flue

Because of the hostile environment, the inside of both flues of this chimney has deteriorated. Notice the cracked flue tiles (left) and the deteriorated joins and/or misaligned flues (right). According to the code, both flues should be relined.

Furnace Flue Problems (gas or oil)

The Furnace's Flue

High-efficiency furnaces do not waste energy by sending heat up a chimney. As a result, temperatures in the flue drop low enough to produce condensation. This water combines with acids in the flue to create acidic moisture. Clay liners are particularly vulnerable to this acidic moisture assault.

  • Flaking plaster and/or peeling wallpaper
  • Staining on wall surfaces due to moisture
  • Excessive moisture in gas or oil flues
  • Excessive soot in oil furnace flues
  • Chimney structure deteriorating
  • Eroded or missing clay liner
  • Carbon monoxide leaking into the home
  • Joint between flue tiles is not sealed

Carbon Monoxide

Carbon monoxide (CO) is a colorless, odorless gas. Sometimes an early warning is flu-like symptoms, but CO can cause brain damage and death with no warning. A damaged furnace flue poses a real threat of carbon monoxide poisoning because this gas can escape through the smallest crack. Also, a partial or complete collapse of the clay flue liner can block the flue and quickly fill the house with deadly gas. Sadly this tragedy occurs in homes across the country every year.

Fireplace & Stove Problems (wood, pellet, etc.)

The Fireplace's Flue

This flue is servicing a fireplace, wood stove, pellet stove, or other solid fuel appliance. It may have undergone a chimney fire or have been connected to an improperly vented appliance, misused wood stove, or exposed to excessive moisture. A damaged flue brings the dangers of fire and carbon monoxide poisoning.

  • Cracked or missing tiles
  • Eroded brick and mortar
  • Excessive or glazed creosote
  • Joint between flue tiles is not sealed
  • Flue tiles not aligned properly
  • Improper chimney draft

Chimney Fires

Chimney fires happen when creosote builds up in the flue and ignites. These fires can rage at temperatures up to 2000 degrees and roar just inches away from your home. The intense heat alone can bring surrounding materials to the flash point and ignite your home. Also, sparks from the fire can find their way through small cracks in the liner and quickly turn a chimney fire into a house fire.

Chimney Lining System

The Solution: Rhino Rigid

Chimney Lining System

Rhino Rigid™ is the premium solution for the problems that plague most chimneys. Modern stainless steel walls provide an airtight and watertight barrier that seals in acidic gases and creosote.

Rhino Rigid™ is especially suited for applications that require a smooth inner surface liner. The smooth wall construction of Rhino Rigid™ permits 15-20% better flow of vented gases due to its reduced turbulence as compared to standard, corrugated chimney liners. In addition, the heavy 24 gauge thick stainless steel wall design is well suited to handle repeated cleanings year after year. This is one tough chimney linger - Rhino tough!

The Rhino Rigid chimney liner is made from 100% prime 304L, 316L or AL29-4C stainless steel. The stainless steel alloy used in your installation will be dependent on your type of heating appliance and its efficiency rating. Your installation professional will discuss these options with you. These modern stainless steel aloys are made to withstand the acidic moisture and extreme temperature fluctuations inside your chimney. Rhino Rigid™ will even contain a chimney fire!

(Actually, Underwriters Laboratories (UL) tested Rhino Rigid™, and has awarded its seal of approval. UL has declared that the Rhino Rigid™ system exceeds standards for chimney safety and can even withstand a 2100 degree chimney fire and still maintain structural integrity.)
