NEW HOUSING AIRTIGHTNESS
REQUIREMENTS
Schiedel provide an air tight sealing kit to
prevent leakage where the chimney passes
through vapour and/or wind barriers. This
sealing kit is used in conjunction with our
ICS50 System Chimney. The use of 50mm
insulation ensures that the outer skin
temperature on the chimney remains low
enough for the EPDM kit to maintain its
elasticity, and remain tight around the ICS50
product, ensuring the air tight joint.
The kit is then fastened securely to the air tight
membrane using the special tape supplied in
the bag, together with the EPDM seal.
INSTALLATION
Schiedel airtight kits are tailored to meet the
outer diameter of Schiedel’s twin wall insulated
ICS50 System Chimney.
The kit is pulled around the outer case of the
ICS50 System Chimney and attached to the
air tight membrane, using the special tape
provided.
SEALING TAPE
The special tape used with the airtight kit is
made from elastic PE film and acryl adhesive.
This combination means the tape is long-
lasting and quick to fit (it sticks immediately).
To make it as easy to use as possible, the tape
comes with a paper liner which is removed
prior to use.
N.B. Do not use tape on steel pipe, only to
seal the joint between the EPDM seal and the
vapour/wind barriers.
APPLICATION
The tape is used to attach the EPDM seal to
the vapour and/or wind barriers. Schiedel
Chimney Systems Ltd does not advise using
the tape on rough surfaces, concrete, brick or
bitumen-based materials. Surfaces must be
clean, dry and grease-free before fitting.
