Product Description
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.
Resistant 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 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.
Lightweight
Pumice is strong yet lightweight allowing one person to lift and
build the chimney units.
The natural properties of pumice
Pumice is a natural
material sourced from the
Hekla Volcano in Iceland.
Pumice is an excellent insulator,
keeping flue gases warm while not
transmitting heat to the outside.
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 pre-formed fire opening ready for
finishing. The Magnum Firechest provides
the opportunity to create fire openings up
to 1.2m wide.
ISOKOAT FLUE SEALING SYSTEM
The Schiedel Isokoat system is an efficient
and cost effective method of re-sealing
a defective chimney shaft. The Isokoat
material is applied to the chimney under
pressure and forced into the cracks
sealing them, re-pointing the joints and
strengthening the walls. For further details
see the separate Isokoat leaflet.
