Installation instructions
Its high surface weight makes HEAVY Duty particularly effective at damping structure-borne noise and vibrations. From a material thickness of 4 cm and when securing the panels with our self-adhesive equipment STICKY, additional mechanical fastening of the soundproofing mats (e.g., with screws) may be useful. Depending on the substrate, the adhesive strength may not be sufficient to permanently support the high weight of the panels.
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.
Temperatureresistance
- 40 °C to + 100 °C
Harmful substance information
Mineral fibre free
Tolerance
This high quality acoustic product is made on our precision machinery according to DIN 7715 Part 5 P3.
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.
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.

Areas of application
‘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.’
