The difference between flexible and rigid chimney liners

Chimney linerCylindrical steel chimney liners can be found in flexible and rigid types. Rigid liners are lowered within the flue and assembled from segments of conduit. Flexible liners are constructed with continuous lengths of corrugated tube that are installed within the flue. Distinctions between inflexible and elastic chimney liners contain price, ease of setup and scenarios where each is suitable to be used.

A tile lining could be fixed or replaced, however, this calls for costly masonry work. Installing a steel liner is frequently a better economic alternative.

The kind of steel liner that’s suitable depends upon the kind of program and the physical arrangement of the chimney the liner will be venting gases from. The steel lining will probably be extended in the highest part of the chimney completely towards the port of the hearth, woodstove, furnace or alternative fuel burning appliance. A stiff chimney lining could be the most suitable alternative, when the flue is straight throughout.

For a quick, straight flue which won’t demand lots of complex joint function, a rigid lining is the least expensive. But, a flue with offsets would need lots of specialized components along with skilled pipe fitting to establish a rigid lining that’s correctly sealed and secure to work. The labour costs associated with installing just one bit flexible liner in a flue will probably be much less expensive compared to the price of the rigid liner.

Potential maintenance costs are another consideration in selecting between a stiff and flexible liner. Because rigid liners are assembled from joints of stuff, they will have more places when compared to just one bit flexible lining does to come up with future escapes. Rigid liners have smooth inside surfaces, therefore that they don’t amass creosote as readily as the inside of the flexible liner.

Some chimney specialists consider the growth and contraction of the corrugated steel in a flexible lining really keeps creosote from accumulating by cracking it and as it collects breaking it free in the grooves.
