Flue Liners

Flue liners are used to build what is commonly called a "traditional chimney" and are usually made from clay or heat resistant concrete.

A typical chimney construction would start with the liners being supported on a suitable lintel or gather if being used above an open fire. The liners are jointed using a flue jointing mortar mix, then surrounded by a minimum thickness of 100mm brick, block or stone work. A minimum gap of 25mm must be kept between the outside of the liners and surrounding masonry, and backfilled with a standard insulating concrete mix.

A choice of gathers bends and chimney pots are available.

We stock the Red Bank concrete flue liners which are a good choice for use with open fires. They are available in a range of round, square and rectangular flue sizes. The 200, 250mm and 300mm square flue liners are popular for open fires and the larger rectangular liners can be used for inglenook type chimneys.

We also stock the Isokern pumice concrete flue liners that are ideal for chimneys being built for use with wood burning stoves.

A few words about Building Regulations
It is a legal requirement that all chimney installations comply with the Building Regulations, which for England and Wales is explained in the Approved Document J. These are minimum requirements aimed at making sure installations are safe. There are also Planning Permission requirements, which are explained on the Regulations page.
