Chimney Liners
If you have a chimney in your home, it’s important to understand the role of chimney liners. These are special materials made from clay, ceramic, or metal that help keep the inside of your chimney safe. When you use your fireplace, the liners help to direct the smoke and other byproducts outside, so that you don’t have to worry about them building up inside your home. Chimney liners also protect the walls of your chimney from getting too hot or getting damaged over time. In fact, most safety codes require that you have a chimney liner installed. So if you want to make sure that your chimney is safe and efficient, it’s important to make sure that you have a chimney liner in place.
Back in the 1940s and 1980s, the National Bureau of Standards conducted tests on masonry chimneys to check how well they held up over time. People were starting to get worried about how safe they were. The results of these tests showed that chimneys without a liner were really dangerous. The researchers even said it was almost a crime to build a chimney without a liner.
Chimney Liners Serve Three Main Functions
1) The liner specifically protects the house from heat transfer to combustibles. In fact, the NBS tests revealed that unlined chimneys allowed significant heat transfer. Furthermore, the test demonstrated that it can pass through the chimney at an alarming speed, causing the surrounding woodwork to ignite in just three and a half hours.
2) It’s important to have chimney liners to protect the chimney from damage caused by combustion byproducts. When these harmful gases get into the brick-and-mortar, they can cause the chimney to break down sooner. The gases are also acidic and can gradually corrode the chimney from the inside, causing heat to spread to nearby flammable materials. This can result in dangerous gases like carbon monoxide leaking into your home, which is obviously not safe.
3) Properly sizing liners are crucial for ensuring the efficient functioning of appliances. Modern wood stoves and gas or oil furnaces require appropriately sized flues to function correctly. The chimney not only allows combustion products to exit the house but also provides combustion air to the appliance through the draft created by the chimney. Incorrect liner sizing can lead to excessive creosote buildup in woodburning stoves and the production of carbon monoxide with conventional fuels. Ensuring that the liner is the right size is essential for achieving optimal appliance performance and safety.
Types Of Chimney Liners
Chimney liners come in three main types: Clay Tiles, Metal, and Cast-In-Place
1) If you have a chimney, it probably has clay tiles in it. They work well if you take care of your fireplace. But there are two things to keep in mind. First, if there’s a fire in your chimney, the tiles might crack because they can’t handle sudden changes in temperature. It’s kind of like putting a cold glass in hot water – it’ll break. If your tiles crack, you need to get them fixed before you can use your fireplace again. Second, if you have a gas fireplace, the tiles might not be able to handle all the liquid that gets produced.
2) When it comes to upgrading or fixing chimneys, stainless steel or aluminum metal chimney liners are the go-to options. These liners are specifically designed to meet the standards set by UL, making them safe and long-lasting as long as they are installed and maintained properly. Stainless steel liners are versatile and suitable for woodburning, gas, or oil applications, while aluminum liners are a cost-effective option that works best for medium-efficiency gas applications. High-temperature insulation is also usually required along with the liners to ensure optimal performance and safety.
3) Installing a cast-in-place chimney liner is an option for those with aging chimneys. These lightweight liners create a smooth and insulated passageway for flue gasses, improving the structural integrity of your chimney. What’s more, they are suitable for all types of fuels. It’s crucial to note that unlined or damaged chimneys can pose serious safety hazards. We highly recommend having your chimney professionally inspected to ensure it meets modern safety standards. Fortunately, there are many options available to make your chimney a secure component of your home heating system.
