Kalzip® Systems

General data and characteristics
5.5 Accessibility/fall arrest systems
For maintenance and cleaning Kalzip
sheets are accessible both during and after
installation without any load distributing
measures. As far as the installation is con -
cerned this will only be valid if the profiled
sheets are zipped on at least one side. The
following table specifies the critical spans
up to which the profiled sheets are accessible
without any additional measures.
It is advisable to install walkways leading
to any units requiring regular maintenance
or operational elements such as daylight
units, chimneys or heating plants. When
exceeding the critical span, load distributing
elements such as wooden planks of
a minium cross section of 4 x 24 cm and
a maximum length of 3 m have to be
installed length – or crosswise over the
Kalzip sheets.
In situations where no rigid thermal insulation
has been installed along the ridge
and eaves areas, the sheets in these parts
of the roof should not directly be walked
on. The reason being that this might lead
to deformation of the flat area of the Kalzip
sheet resulting in a possible accumulation
of rain water.
The last free sheets along the gable end,
single unzipped sheets and of course
translucent panels should not be walked
on. During the installation of the roof any
areas which are frequently walked on or
used for the transport of materials should
be protected by temporary walkways,
which should be secured with seam clips
to prevent them from sliding down.
The Kalzip fall arrest system is a reliable
solution to secure walkways on the finished
roof. It consists of a stainless steel
rope which is fastened to permanently
fixed Kalzip roof anchors and coupled to
the safety harness by means of a guide
link. Project related planning is carried out
by Kalzip GmbH.
