Pumice - naturally better - Pumice chimney liner
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 –
Resistant to temperature change
Pumice does not expand or contract with temperature change. This reduces the possibility of cracking and structural damage that can occur with other products.
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. 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 and Steel Frame construction. Isokern chimneys have been installed in Europe for over 60 years.
DM (Double Module)
The Schiedel Isokern Double Module block system is a quality chimney system, used extensively in Scandinavia and other parts of Europe. The double wall system maintains flue gas temperatures while preventing heat transference to the outer casing. The separation of the inner and outer components also allows for thermal movement, reducing the risk of cracking and subsequent leaking or staining. It is simple and quick to build. The Double Module is available in 3 outer casing sizes - DM36, DM44 & DM54.
The Schiedel Isokern flue liner range consists of over 17 different sizes. They can be used for newbuild, extensions and relining existing chimneys.
The Shiedel Isokern range of firechests are supplied as flat packs. They can be easily and quickly constructed to produce a neat and pre-formed fire opening ready for finishing. The Manor Firechest provides the opportunity to create fire openings up to 1.25m wide.
