A recent Swedish field study has proven that noise at the
workplace will negatively affect the health of employees. A good
indoor environment with proper acoustics is key for the well-being
and concentration of the employees and reduces their stress
Sound-absorbent solutions for ceilings and walls may reduce
reverberation and minimize noise in office facilities etc. Noise is
undesirable sound that causes damage or is troublesome. A well
dimensioned ventilation system must therefore be quiet. As a result
of their soft surface, textile ducts have a positive impact on room
attenuation as they act as sound baffles in the ceiling, absorbing
and breaking up part of the noise reflected in the ventilated
Excellent acoustic properties
These properties helped KE Fibertec secure the order for
Walkden High School in Manchester, UK. Their new building was
constructed as part of BSF, Building Schools for the Future, and KE
Fibertec supplied textile ducts for the delivery of large amounts
of fresh air into all classrooms without noise or draft problems.
In this way textile ducts helped provide a good and healthy indoor
environment for both students and staff.
To ensure that the class rooms would not receive any unnecessary
noise from the ventilation ducts the consulting engineers requested
a noise test in order to establish how much noise is absorbed by
The test was performed by the University of Southampton for the
purpose of establishing the room attenuation effect through textile
ducts. The result of the test contributed to specifying textile
ducts for Walkden High School and for another five schools.
more about the solution for Walkden High School.
A textile duct from KE Fibertec is both a sustainable and energy
efficient alternative to ducts made of steel.
There are many benefits:
KE Fibertec has supplied textile based ventilation to many
different comfort installations where the demand for draft-free,
uniform and efficient air distribution has been combined with
