WALLperf® is an additional option within the IN® absorption panels range. It is mainly 180
meant for stadiums, large halls, airports, subways and bus stations, as well as for 2.5
industrial applications. It can also be applied in moist environments or outdoors.
This panel's structure is made on a perforated metal lacquered plate, which gives the
product a good robustness; the interior is built by combining absorbent raw materials
made from mineral and synthetic fibers.
The typical public and industrial spaces require an adequate planning of acoustics in
order to provide good sound perception. The brand IN® has come up with this line of
products which has a good absorption in the largest common noise range.
Although it is different in aesthetic terms, the WALLperf® is attractive and has a pleasant
design. The WALLperf® is available in multiple colors with the same acoustic features. It
is easy to install on the walls and ceilings with its own accessories.
