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

In 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.

For those who expect more - aixFOAM Premium sound absorbers

Our sound absorbers made of thermoset acoustic foam are the ideal solution for rooms with particularly high soundproofing and fire protection requirements. They owe their unsurpassed acoustic properties to the extremely fine, open pore structure that almost completely absorbs sound. They are flame retardant without the addition of flame retardants and thus meet many regulations to ensure fire safety in public buildings.

Stacked sound absorbers with increased fire protection class
  • Maximum sound absorption
  • Flame retardant according to DIN 4102 B1
  • Form-stable and colour-fast – no yellowing!
  • Very low weight
  • Antistatic, fibre-free and elastic

Absorption values

The measurements of the sound absorption coefficient were determined according to DIN EN ISO 354 (reverberation room) and refer to an absorber area of 100 cm x 50 cm.

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. The sound absorption coefficients according to DIN EN ISO 354 (reverberation chamber) 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.
