This high quality acoustic product is made on our precision machinery according to DIN 7715 Part 5 P3.

During the production (foaming) of this acoustic material different sized pores (voids) can arise. Voids are typical for the material, do not represent a quality defect and do not affect the acoustic properties of the absorber.

More information about this product is available, if required, in the accompanying datasheet. We are happy to provide you with this upon request.

Absorption values

The measurements of the absorption coefficient were performed on PUR-ES acoustic foams from RWTH Aachen. All values refer to absorbers with a size of 100 cm x 50 cm and were calculated according to DIN 52212.

Sound absorber/ sound insulation in the reverberation chamber when determining the absorption values
Our aixFOAM sound absorbers have been tested for Hertz and pores in the reverberation chamber of renowned institutions such as RWTH University or the Technical University in Aachen. The sound absorption coefficients according to DIN 52212 stated above were calculated in extensive measurements.

Profit from sound insulation directly from the manufacturer!

At aixFOAM we make sound insulation for applications in room acoustics and technical acoustics. And because we do this particularly well, we have been doing it for 60 years. Over this time we have been constantly working on the further development of our products and therefore are able to offer you highly effective sound absorbers in a modern design.

Our aixFOAM philosophy: We combine customer-oriented advice with the individual, needs-based production of sound insulation solutions. Or in other words: We help you with free advice to find the ideal sound insulation for your project and start to make your absorbers directly after receiving your order. You then receive your sound insulation directly from the factory – naturally in the best quality.

  • Use of high quality acoustic foams from Germany
  • Precision manufacturing on the latest CNC cutting machines and systems
  • Standard solutions or individual small and series manufacturing of noise insulation

‘FLAT Tec is a very flexible sound absorber, which is suitable both for soundproofing and sound insulation in the technical area. Even at small material thicknesses, its absorption effect is considerable and with the heavy acoustic foil laminate is reduces material vibrations even more. Many customers value FLAT Tec as a base material for noise dampening in machinery construction, shipbuilding and for casings and switch cabinets.’
