7 Advantages of Using a Flexible Flue Liner

A flexible flue liner is a great alternative to the rigid type. It is made of corrugated stainless steel and expands and contracts according to temperature fluctuations. Many homeowners struggle with unsatisfactory chimney performance. Although various factors account for this, an inefficient flue frequently emerges as a cause. Fortunately, there are corrections you can make to improve your chimney efficiency. One simple measure involves obtaining a flexible flue liner. Below are 7 advantages.


Flexible liners are easier to install than the rigid variety. The single length of flexible liners makes it easier to fit into the chimney. The rigid liners however must be installed in pieces. There’s always the possibility that a piece may drop down into the chimney during installation. The partially assembled portion may also drop before installation is complete. Retrieving any dropped portions adds to the installation work. With a flexible liner, installation takes less time and it is not as laborious. This makes it easier for you to enhance your chimney performance while saving on costs.


The adjustable length of flexible liners is great for taller chimneys or chimneys that may have contours or even just slight bends. Fitting the liner into the chimney is not as complicated as when a rigid flue liner is used. The versatility of flexible chimney liners makes it easier to undertake home maintenance work yourself. It also helps to keep costs down.

Less Creosote

Flexible flue liners accumulate less creosote than the rigid flue liners, especially when used on wood fireplaces and stoves. The flexing process loosens the creosote and causes it to fall off. The alternating expansion and contraction does not allow creosote to build up as heavily on flexible liners.

Easier Maintenance

One of the factors that create regular chimney cleaning and maintenance work is the accumulation of creosote. Flexible liners prevent much buildup of creosote. This helps to reduce maintenance work required on the chimney. Flexible liners can also be easily removed when cleaning is necessary. This enables a more thorough cleaning job. Less maintenance work also helps keep overall home maintenance costs on the lower side.

Higher Safety

Installing a flexible liner is a great way of minimizing the risk of a chimney fire. Heavy buildup of creosote is more common with rigid flue liners. A flexible liner adds to home safety while adding to chimney efficiency.

Improves Chimney Draft

Less buildup of creosote from a flexible liner improves the chimney draft. This enhances chimney efficiency. Improved chimney efficiency also results in greater energy efficiency. This makes the fireplace more effective in household warming.

Adds to Home Value

The various benefits of flexible flue liners improve chimney efficiency. An efficient chimney is a significant consideration in home valuation. It can actually hasten the sale of a house. Home buyers prefer to commit to a house that needs fewer repairs. Quite often, a chimney emerges as one area in need of urgent repair. Flexible liners add to home value.
