Kalzip structural cassette
Suitable for both roof and wall applications,
Kalzip structural cassette are available in
both aluminium and steel and are available
as a tested and proven alternative lining
element for the Kalzip standing seam
system. With good strength and stability,
Kalzip structural cassettes are suitable for
long span applications and there is also a
reduced requirement for structural
steelwork.
Once in position the interior face of
the cassette provides a clean and pleasing
appearance with no visible fixings.
For increased spanability a special
section can be inserted into the side lap
of the cassette.
Structural cassette materials and
finishes
Kalzip structural cassette are manufactured
from high grade steel to BS EN 10346 or
from aluminium alloy.
Perforated versions are available where
acoustic absorption is required. The sheets
also have the strength to support the
introduction of additional mass such as
particle board or plaster board where there
is a requirement for good sound reduction.
For further details, please refer to the
acoustic section, or contact our technical
department.
Standard finishes for cassette, available
on a short lead time are:
Alternative perforation patterns and sizes
are available to suit specific requirements.
Perforated cassette will improve the
acoustic conditions within a building by
helping to optimise reverberation times.
Furthermore, the cassette can contribute
to noise reduction and noise containment
within the building by the inclusion of mass
above the cassette such as particle board
or plaster board and the inclusion of air
spaces within the system. If the application
requires, the system can be configured
for both acoustic absorption and noise
reduction. To obtain the correct
specification for precise acoustic
requirements, please contact our
technical department.
• Hot-dip galvanised, natural finish. Ideal
for situations where the cassette is not
visible or where visual appearance is
not critical.
• White polyester coated on hot-dip
galvanised substrate. This finish is highly
durable, resists scratching and has
good formability, suitable for
exterior soffits.
