Our Heavyweight against noise

The fire classes of the aixFOAM absorbers do not only refer to the material, but always include the products including the mounting options offered by us, such as our STICKY self-adhesive kit.
More information about the fire classes of our sound absorbers is available the relevant aixFOAM knowledge article.
Please note: If you use HEAVY Duty for structure-borne sound insulation, decoupling, or impact sound insulation on the floor, you must weigh it down with a stable and load-bearing cover plate (e.g., chipboard, multiplex board, OSB board) to ensure even load distribution. Place the plate evenly over the HEAVY Duty soundproofing panels. This setup prevents the heavy foam from being compressed at specific points under load, which could cause devices, instruments, or furniture placed on top to tip over.
More information, such as the mechanical load capacity values of our HEAVY Duty heavy foam is available in the accompanying datasheet if required. We are happy to provide you with this upon request.
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.

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.

‘The heavy acoustic foam HEAVY Duty is the perfect product for any sound insulation area. With its high mass, it absorbs noise effectively and stops the transmission of structure-borne sound. It is suitable both as footstep dampening under the pressure distribution layer in floorings, and as sound insulation in sound studios and for decoupling drums or singing booths.’
