Chimney Liners

There are two types of stainless chimney liner: Rigid and Flexible. There are many variables to choosing what type and size of stainless steel liner.  The type of steel alloy liner depends on the material being burned thus what types of exhaust will be going up the chimney; whether it be gas, oil or wood.

Here are some situations relating to your existing chimney that would require a stainless steel chimney liner:

1) The existing chimney is unlined. In the past, some masonry chimneys were built without any liner at all. Without a liner, smoke exhaust can leak through the mortar joints into the house. Further, liquid creosote will eventually dissolve the binder in the mortar and soak into the joints, with the potential of a fire in the chimney.

2) The existing liner is cracked or damaged. Masonry chimney liners are made of clay or pumice, which can crack from chimney fires, settling, earthquakes or other causes. Cracks in a pumice or clay flue liner will let the smoke and liquid creosote through, leading to the same problems described above.

3) The existing chimney is lined, but the liner is too large. Oversized flues cause numerous problems, causing poor draught with resulting smoke spillage into the house when they're cold, and the kind of excessive creosote formation that leads to chimney fires.

As mentioned earlier your liner will be either rigid or flexible. A flexible liner would be needed when there is a bend in the chimney where a straight liner wouldn't be able to go.  Measurements need to be taken to ensure that the size of the liner will fit the flue as it is necessary for it to be large enough to handle the output or exhaust of the chimney and will still fit in the available space.
