ISOKERN PUMICE installation instructions

Pumice is a natural insulator; this is the unique property that separates pumice from all other chimney material. Schiedel Isokern is noteworthy for its flue & chimney products manufactured using high quality pumice which is recognised throughout Europe and USA.  Please take a look at the guides below. You can also download the Pumice Brochure, which has various installation guides for Double Module and Liner systems.

Product Description

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.
 
DM (DOUBLE MODULE)
 
Schiedel Isokern DM block system is a high quality System Chimney. 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 DM is available in 3 outer casing sizes - DM36, DM44 & DM54. 
 
FLUE LINERS
 
The Schiedel Isokern flue liner range consists of over 15 different sizes. They can be used for newbuild, extensions and relining existing chimneys.
 
FIRECHESTS
 
The Schiedel Isokern range of firechests are supplied as flat packs. They can be easily and quickly constructed to produce a neat and preformed fire opening ready for finishing. The Magnum Firechest provides the opportunity to create fire openings up to 1.2m wide. 
 
GARDEN FIREPLACE RANGE
 
The natural pumice gives this outdoor fireplace all the insulation needed to have a safe and spectacular focal point of any garden. The relatively small footprint also means that this can be placed against any wall in even the tiniest of gardens or yards.
