Silentmax® acoustic panels are made of fine PET fibers. They are antistatic against dust and practically maintenance-free. They can be cleaned with a vacuum cleaner either dry or wet. They are light, breathable, vapor permeable, chemically resistant. They are attached to the wall by hanging, using corner strips, Velcro, gluing or anchoring with spacer screws. They are attached to the ceiling by gluing or using suspension cables.

Basic properties

Dimensions: 2440 mm x 1220 mm, thickness 12 mm
Weight: 6.9 Kg / panel ( 2.3 Kg / m2)
Dimensions can be easily adjusted with a hacksaw.

Sound absorption parameters

They are characterized by excellent acoustic absorption in a very wide spectrum of frequencies. Absorption coefficient NRC=0.9 in the frequency band of the spoken word 500 Hz to 5 kHz. The NRC coefficient depends on the location of the panels in the space and their configuration.

Silentmax® acoustic panels are made from recycled PET fibers with a thickness of 18 to 22 µm. The fibers are pressed under a strictly defined temperature and pressure so that the fibers melt and join at the point of their mutual contact. The internal structure and precisely defined density (the ratio of fibers, their gaps, the free space between them) predetermine the property of extreme acoustic absorption.


We can print Silentmax® acoustic panels with any motif according to the customer’s wishes. A company logo, photo or motif on the acoustic panel improves the acoustics and at the same time functions as an aesthetic accessory. The print does not degrade the acoustic properties. The color has a very high viscosity, thanks to which the individual color droplets surround the 20um thick fiber. The structure of the fibers is thus still active even with the print.
