The properties of a pumice chimney system

Since pumice is a natural insulator, it’s the perfect material for a new build chimney. This unique property separates pumice chimney systems from all other types of chimney block systems, making Isokern chimneys the preferred solution of many homeowners.

With the help of a pumice chimney system, your heating appliance will easily reach optimum temperature within record time of lighting. Plus, a chimney block system made from pumice will stay warm for longer, maximising the efficiency and heat output of your wood burner and reducing the possibility of soot build-up in the flue.

Isokern Flue Liners

The Isokern chimney flue liners make for a great pumice chimney system when building a new chimney which will be surrounded by stone, brick or block. Available in a range of sizes, the Isokern chimney linings are compatible with all fuel types; however, they are not suitable for condensing appliances such as pellet or biomass. As well as new build chimney systems, these pumice liners fit perfectly within refurbished masonry chimneys.
