ABSORPTION PANELS FOR THE BEST POSSIBLE ACOUSTICS

acoustic products

INTRODUCING
In many modern environments the emphasis has
been to move to more open plan areas.
Whether it is a school, an office, or a church,
these new spaces with their larger areas can
accommodate more individuals all going about their
day, often not aware of the constant distraction
from noise due to increased reverberation times.
For years Alco Wall Systems has
been involved in the manufacturing
and installation of acoustic movable
walls in many of the UK’s leading
Hotels, schools, leisure environments,
and commercial institutions.
Now Alco Wall Systems introduce
SoundFlex, a range of wall-mounted
absorption panels to enable the
reduction of reverberation time by
dissipating the sound energy,
which compliments the sound
insulation provided by our acoustic
movable walls.
SoundFlex absorption panels come
in a selection of designs and finishes
to enhance any environment.
They are lightweight, high
performance absorption panels
that create an effective acoustic
environment in a multitude of uses
where sound reverberation needs
reducing.
Manufactured in the UK
SoundFlex absorption panels are
manufactured at our own factory in
Loughborough where our acoustic
laboratory played an important role
in obtaining first class results in
the development of the SoundFlex
product.
ABSORPTION PANELS FOR THE BEST POSSIBLE ACOUSTICS

Final refinements were made with
the assistance of our two in-house
IOA qualified acousticians when
testing of the boards took place
at an independent laboratory.
Sound Design
In any space where the reverberation
time needs reducing, introducing
SoundFlex absorption panels will
greatly help to create a better overall
environment with improved levels of
intelligibility. SoundFlex absorption
panels are environmentally friendly
with no cutting or wastage as each
panel is bespoke and easy-to-install
making it one of the best systems
available.
SoundFlex absorption panels can
achieve a range of sound absorption
classes from E to A dependent on
the design.

Other Applications
An additional use for the Soundflex absorption panels is
to incorporate the panels into the balustrades to reduce
reverberation time in the public areas.
The example shows the University of Lancaster, and
demonstrates the panels can be installed on both sides to
create maximum absorbency.
The thickness of the balustrade determines the potential level of
absorbency achievable as a greater internal depth increases the
classification potential.
