Chimney Liner Varieties
Relining a chimney after following the installation instructions is a very simple process.
Afterward, the new stainless steel liner is dropped down the chimney from above. One reliner will be stationed above the roof, and another will be positioned at the base of the chimney, with the use of a rope, to help pull and direct the liner as it is lowered into place.
After the liner is installed in a wood-burning fireplace, the reliner will parge the smoke chamber by hand to insulate and smooth out the walls. This improves the smoke chamber’s drafting and prevents creosote buildup in the future. The liner is then encased in an insulating mixture.
To install a hearth stove or appliance (gas furnace, oil burner, or water heater), a stainless steel “t-connector” must be attached to the liner per NFPA regulations and the manufacturer’s guidelines.
Finally, Priddy’s chimney reliners will install a top-mounted damper system or termination cap to keep water and animals out of the flue of your fireplace and appliances.
In order to contain the byproducts of combustion, divert them away from the house, and protect the chimney’s walls from corrosion and heat, a masonry chimney is lined with ceramic, clay, or metal. In order to prevent potential dangers, unlined chimneys are prohibited by most fire codes. National Bureau of Standards research indicates that an untreated chimney may transfer so much heat that nearby wooden structures can catch fire in as little as three and a half hours.
Chimney liners prevent the transfer of heat from a fireplace to flammable building materials. Liners also protect the chimney’s brickwork from the corrosive byproducts of combustion, which can shorten the chimney’s lifespan and endanger the safety of the people living in the residence. Metal, clay tiles, and cast-in-place liners are the three most used materials for lining chimneys.
Chimneys that need repairs or upgrades often have metal liners installed, often composed of aluminum or stainless steel. Stainless steel is suitable for gas, oil, or wood burning systems, whereas aluminum is utilized for medium efficiency gas systems. The liner is installed with high-temperature insulation for enhanced efficiency and safety.
Chimney liners typically are made of clay tile. It’s perfect for an open chimney system, doesn’t break the bank, and is easy to find. However, in a chimney fire it does not absorb or disperse heat quickly or uniformly. Flue tiles may fracture or split as a result of uneven development. Modern gas systems produce liquid waste products that can’t be contained by clay tiles.
Cement-like in composition, cast-in-place liners for chimneys are surprisingly lightweight. To provide a smooth, insulated route for flue gases, it is cast to fit within a chimney and then put there. By adding this liner, the chimney’s longevity and safety are improved. To find out if a new metal, clay tile, or cast-in-place liner is needed to bring the system into conformity with current fire and safety requirements, homeowners should have a chimney inspection.
