Why Do You Need to Install Chimney Liner in New Jersey?
Chimney liners act as an additional layer of protection between the chimney's interior and the framing of your house. As common flaws in the chimney can occur, this adds another layer of security. No matter how minor, defects will start a mechanism that will further erode the chimney and endanger your family's safety by introducing health hazards. Poisonous gases could infiltrate your home.
Combustible creosote or soot can outflow through these openings and accumulate outside the chimney flue liner.If the creosote in this region of the chimney catches fire, substantial damage will result inside the flue. Before the 1940s, most homes were constructed without a chimney liner. As a result, house and chimney fires became more prevalent. Some solid reasons why you need a new liner today: If the chimney lacks a liner, was poorly built, or is rotting or faulty.
Chimney Liners Serve 3 Main Functions
1. Shielding the home from combustible heat transfer:
In the NBS experiments, unlined chimneys allowed heat to passthrough the chimney so quickly that the adjacent woodwork caught fire in few hours.
2. Shielding the masonry from corrosive byproducts of combustion:The NBS tests revealed that allowing flue gases to enter the brick and mortar would decrease the chimney's useful life. The flue gases are acidic, and they practically chew away at the mortar joints within the chimney. If the mortar joints deteriorate, heat spreads more quickly to surrounding combustibles, and toxic gases such as carbon monoxide can spill into the home's living areas.
3. Providing an adequately sized flue for maximum appliance efficiency: To function correctly, modern wood stoves and gas or oil furnaces require an appropriately sized flue. The chimney is responsible for allowing combustion products to exit the building and supplying combustion air to the appliance through the chimney's draught. A liner that is incorrectly sized can cause unnecessary creosote accumulation in wood-burning stoves and carbon monoxide emission by traditional fuels.
What Types Of Chimney Liners Are Available?
Clay Chimney Liners: This type of liner is usually mounted during a house building.This is a more traditional style of chimney lining used in homes since the early twentieth century. Clay tile is a tried-and-true style of chimney liner that can handle extraordinarily high temperatures without fail. The clay lining can withstand the toxic materials that fly up the flue and into the air above.Best of all, the clay material is very inexpensive, and the lining can last for up to 5 decades before having to be replaced.
There are some downsides to using clay chimney liners. For instance, since the clay is arranged in rectangular tiles, it does not make a seamless interior. Air may get trapped in the openings, affecting the normal draught within your chimney.If the tiles get too old, they will begin to crumble, putting you at risk of a house fire. Contact the nearest Chimney repair company to check your chimney's state and determine whether it needs to be replaced.
Pros: They are cheap, widely available, and work admirably for properly managed open fireplace chimneys.
Cons: They cannot quickly consume and uniformly disperse heat during the sudden temperature increase that happens during a chimney fire, allowing the flue tiles to crack and break apart. The second drawback is that tiles cannot sufficiently absorb the liquid combustion by products emitted by modern gas appliances.
Cast-in-liners: These liners are usually used to reinforce an existing liner within the chimney. It strengthens the existing chimney and offers a solid and robust liner. A cast in liner, similar to a misshapen clay flue, will produce anew shape within the flue. This form of the liner is not harmed by the heat or corrosive chemicals emitted during combustion, making it highly durable. Cast in liners, like clay liners, can last up to 5 decades.
Cast-in liners are installed by pumping a mortar mix through the chimney. This mixture is pumped around an inflated rubber balloon to produce a very smooth surface within the flue. This is a cost-effective and long-lasting approach that comes highly recommended.
Pros: They are permanent liners that are ideal for all fuels and can increase old chimneys' structural stability.
Cons: Installation is complex and can be prohibitively expensive.
Metal liners: Metal liner scan be mounted in almost every chimney. These can be rendered of any size or form. These liners are generally made of stainless steel. There are two kinds of metal chimney liners: rigid and flexible. The shape of your chimney will deter mine which type of chimney liner your chimney company will use.
Rigid liners are suitable for straight-up chimneys with no twists or turns, while flexible liners can be found in chimneys with curves or bends. These can also help retain higher heat in the chimney and eliminate moisture that can cause corrosion and destruction. It also keeps heat from entering the pipes inside the home's system. These stainless-steel liners are ideal for existing chimneys that either does not have a liner or need replacement.
Pros: Metal chimney liners are highly secure and reliable if correctly designed and maintained. Stainless steel is appropriate for wood-burning, coal, or oil equipment, while aluminum is only affordable for some medium-performance gas applications. For protection and efficiency reasons, high-temperature insulation needs typically to be used in combination with the liners. High point chimney only uses stainless-steel liners, so they are guaranteed for life, whereas aluminum liners are not.
Cons: Significantly more costly than clay flue liners.
