ACOUSTIC SAIL SYSTEM COMPLEMENTED
BY COOLING AND VENTILATION
INDUSAIL SONIC acoustic absorption
The high sound absorption values of the sails are achieved thanks to especially effective materials and their optimal
arrangement in the sail.
All three sail types are equipped with sound-absorbing acoustic fleece on the room side. The
specified sound absorption values were determined in accordance with DIN EN ISO 354 and DIN EN ISO 11654 by an
external institute for sound-related product optimisation. The INDUSAIL SONIC silent sail is additionally equipped with a
highly absorbent insulating material made of polyester, which achieves a particularly high sound absorption at different
ceiling distances.

Flexible design of office spaces coupled with complex acoustic requirements can be
implemented using the SONIC range. Kiefer Klimatechnik supports you in producing an
optimal system design.
Optimising the interior acoustics
Acoustic sails can reduce nuisances such as noise in interiors. This improves working conditions and performance. In open-
plan offices in particular, it can often be hard to concentrate when others are talking loudly. Audibility in the room, increased
speech intelligibility and low reverberation times are important room acoustic criteria that increase the acoustic quality of the
room and thus the productivity of the users. The ceiling is the largest continuous surface in a room and can reduce sound
propagation with sound-absorbing ceiling sails. This increases the wellbeing, satisfaction and performance of the people in
the room.
