Isokern Chimney Systems

The Isokern Double Module chimney system provides a lightweight, easily installed and versatile chimney which can be used internally or externally.

Isokern systems are suitable for use with burning appliances in new and refurbishment projects. They are ideal for masonry and timber frame

The staggered joints of the outer and inner blocks, which are laid at the same time are designed for safety and stability. Chimney insulation is maximised by this double layer of pumice, separated by an air gap.

There are many more benefits to the Isokern DM system:


Air gaps between outer casing and flue prevents surface staining


Highly insulated pumice for better draw and minimum heat loss


The individual blocks are light, and easy to handle.


Suitable for wood logs, solid fuel, oil and gas.


Good resistance to temperature variations.

Your heating appliance can reach its optimum performance quickly due to the effect of the pumice’s insulating properties on the flue gases. These properties also have the benefit of reducing soot build-up and condensation, by keeping the chimney warmer for longer after reduction in the appliance’s heat output.

The Isokern DM system comes in a range of internal diameters, enabling it to be used in a variety of settings/construction projects.

Isokern DM chimney systems are versatile – they can be used for:


Open fires


Inset fires


Freestanding stoves in recess


Freestanding stove with external chimney
