Isokern Chimney Systems

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

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


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.


The outer and inner blocks are laid at the same time but have staggered joints for stability/safety.


The double layer of pumice separated by an air gap maximises the chimney insulation.


These chimney systems are suitable for wood logs, solid fuel, oil and gas.
