Traditional Chimney Systems
Pumice - naturally better!
Pumice is a natural insulator. This is the unique property that separates pumice from all other chimney materials.
The insulating properties of pumice allow the flue gases in the chimney to quickly reach their optimum temperature enabling the heating appliance to reach its optimum performance shortly after lighting.
It also keeps the chimney warmer longer as the heat output of the appliance decreases - once again aiding performance and reducing the likelihood of condensation and soot build-up.
The Natural Properties of Pumice
Resistance to temperature change:
Pumice has very little expansion and contraction with temperature change. This reduces the possibility of cracking and structural damage that can occur.
High insulation properties:
Pumice is a natural insulator, able to maintain the temperature of flue gases when other products have allowed the temperature to fall below the dew point.
Pumice is strong yet lightweight allowing one person to lift and build the chimney units.
Pumice is sourced from the Hekla Volcano in Iceland
Schiedel ISOKERN products can be used for new chimneys and for the refurbishment of existing chimneys. The ISOKERN chimney systems provide a lightweight, easily installed and versatile chimney which can be used internally or externally. The systems are suitable for use with burning appliances in new and refurbished projects. They are ideal for masonry, timber frame and steel frame construction. ISOKERN chimneys have been installed in Europe for over 60 years.
