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.

This sound absorber is part of our Green Balance Line. The raw materials used have up to a 50% lower CO₂ footprint* and are manufactured with a reduced environmental impact.

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.

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 65 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.
