Décor Acoustics is proud to offer products made from Acoustifoam™, a flexible, open-cell thermoset polymer from Germany. Not only is the Acoustifoam lightweight and easy to install, but it provides unmatched acoustic value, while also inherently having a Class “A” fire rating (without adding additional additives).

Processed into large blocks that are then cut or cnc’ed into the desired shape/pattern, Acoustifoam is the ideal element for absorbing sound within spaces. Created in a natural white color, Acoustifoam can also be custom colorized via our Pantone Custom Coloring (PCC), wherein we use a proprietary non-bridged paint formulation to ‘custom color’ per our clients’ desires.

Acoustifoam provides acoustic excellence, both in shape and in colorways, that enables you to put your ‘design’ signature on the space.

What is Acoustifoam™?

Acoustifoam is an ultralight, fiber-free open cell foam, that excels with absorbing sound. Developed in Germany, it is non-fibrous, itch-free, and naturally (without additives) achieves a Class ‘A’ for fire (ASTM E84). It’s low thermal conductivity and superior thermal insulation properties make it one of the best acoustically absorptive materials available. It is flexible, easy to shape, and can easily be colored (any color can be specified) with our Pantone Custom Coloring (PCC) without any acoustic degradation.

Acoustifoam comes in Flat Panels (which can be mounted directly to a wall/ceiling or hung vertically as a baffle), decorative Tiles (an amazing offering of 10 CNC’ed shapes), Baffles (sinuous and cylindrical versions), and Ceiling Tiles (either for Direct glue applications or installing within a grid).

NRC and Sound Absorption Co-Efficient

Acoustifoam excel with NRC and sound absorption. The Sound absorption coefficient is the ratio of absorbed vs reflected energy, effectively the incident sound that strikes a material and is not reflected back. That absorbed acoustic energy turns to heat on a microscopic level. Sound Absorption coefficient is reflected in the materials’ NRC rating (or results). The NRC test (ASTM C423) analyzes a material at 6 different frequencies: 125Hz, 250Hz, 500Hz, 1000Hz, 2000Hz and 4000Hz, though creates an average based on the 250-2000 Hz range, which effectively creating an overall value (a summation if you will) of the materials’ sound absorption properties.

Here are the sound absorption ratings and NRC of the Acoustifoam at standard thicknesses:

Thickness 125 Hz 250 Hz 500 Hz 1000 Hz 2000 Hz 4000 Hz NRC
1.5″ 0.17 0.28 0.84 0.99 1.03 1.01 0.90
2.0″ 0.23 0.48 1.08 1.19 1.16 1.11 1.00
3.0″ 0.45 0.87 1.26 1.07 1.06 1.10 1.05
Thickness 1.5″ 2.0″ 3.0″
125 Hz 0.17 0.23 0.45
250 Hz 0.28 0.48 0.87
500 Hz 0.84 1.08 1.26
1000 Hz 0.99 1.19 1.07
2000 Hz 1.03 1.16 1.06
4000 Hz 1.01 1.11 1.1
NRC 0.9 1 1.05
For comparison, commonly used PET felt (usually specified at a thickness of 9mm) has an NRC of 0.30. And, inherently PET felt is NOT fire-retardant, so in order to make it suitable in most commercial assemblies, it must go through a chemical additive treatment to give it a suitable rating.
