 All absorption factor measurements of have been taken at polyester acoustic foams by the Institute of Technical Acoustics (ITA), Aachen University. Incidental absorption factor results greater than 1 may occur with the practical measurement methods used by the ITA. They originate from the fact that the operative surface of absorbers slightly exceed the geometrical surface.


By the profiled surface (convoluted foam) and the microporous structure of these acoustic foam panels, air particle oscillation is decelerated and converted into thermal energy. The product ranks among the classical absorbers and is extremely versatile.

Please note that this aixFOAM product is invariably made to order due to the variety of available options we as a manufacturer are able to offer. Thus all our customers receive their personal aixFOAM - acoustical absorption product, explicitely delivered as requested according to their needs and demands.

This product is manufactured according to DIN 7715 Teil 5 P3.

Convoluted foam SH0021:

SH0021 is acoustic convoluted foam that is available in two different materials - polyester & polyether (with or without flame-retardant) - as well as in different material strengths between 30mm and 60mm. convoluted foam is primarily used for acoustic insulation, the demand is growing. Depending on the material strengths SH0021 can reach absorption grades between 0.10 and 1.02. This already covers most of the favoured sound insulation or isolation. These special fields of application for this kind of convoluted foam affect several forms of sound insulation.  Besides that it can be installed in the machinery-encapsulation or, if large enough, inside of the machine itself with the help of an optional installation device, leading to a sound insulation of the affected machine. This might be necessary due to legal sound regulations at the working place. The convoluted foam panels can also help you reducing the sound emissions of electrical devices such as servers in server rooms.

Sound insulation of engines and engine bays deployment in the area of vehicle- and boat construction

Furthermore SH0021 convoluted foam is deployable when it comes to the acoustic insulation of engines and engine bays and therefore in the area of vehicle- and boat construction. In addition to that the panels can be attached to sound-insulating doors. Sound-insulating can be found in machine rooms as well as in discothèques, cafés, rehearsal rooms and in laboratories. In our days these doors are and important part of noise regulations.

Assembly options   
aixFOAM self-adhesive equipment    
The back of the absorber is coated by machine in the factory with a solvent-free adhesive system and covered with lining paper. This lining paper must be removed by the customer before bonding.    
aixFOAM assembly/suspension cassette    
With this product, you are purchasing a very high quality assembly option. The aixFOAM cassettes are produced from anodised aluminium and turn every aixFOAM basic product into a Premium Absorber. This option gives you the opportunity to mount your absorber upright, horizontally or suspended from the ceiling and, of course, to take it down at any time. The aixFOAM assembly and suspension cassette is assembled with the aixFOAM Absorber of your own choice. Alternatively, you will find the assembly/suspension cassette unassembled as an individual product in various packing units in the "accessories" category.
The enhancement of the acoustic effect!   
Apart from the purely physical aspect and the statical bearing function, aixFOAM flat-mounted- or pendant assembly cassettes also have the characteristic of being able to absorb lower acoustic frequencies by means of the so-called ‘counter vibration effect’, and therefore to enhance the degree of absorption by the aixFOAM sound absorber of your choice more intensively in the lower frequency range (Resonator). Important information on this feature can be obtained from the Article: "Flat-mounted- or pendant assembly cassettes" in the Section "Accessories".

aixFOAM heavy acoustic film lamination   
These are heavy, very flexible films without lining material that are minerally filled. The heavy acoustic film has an above-average surface weight, whereby deep frequencies and material vibrations are absorbed. The composition of the heavy acoustic film provides it with excellent absorption properties, including in low temperatures. In addition, the material is designed to be flame-retardant and is laminated under your aixFOAM basic product as a base material with this option. Alternatively, the aixFOAM heavy acoustic film SH0131 is also available as an individual product (refer to overview of products).

Processing instructions Acoustic Heavy Foil
aixFOAM Acoustic Heavy Foil is equipped with a specially developed acrylic based adhesive system. The adhesive system must be used only on flat surfaces at macro level, e.g. sheet metal and aluminium. On rough surfaces the adhesive system can be used as mounting asssistance only. Further information is available in our technical datasheets and processing instructions, which could be send free of charge upon request.

Material Options   
Fire classification UL 94 HF1   
Fire classification FMVSS302 DIN 75200   
Fire classification FAR 25.853 with test certificate from Lufthansa Technology Laboratories (refer to online advisor)   
Fire classification DIN 4102 B2 (exclusively with aixFOAM self-adhesive equipment) (refer to online advisor)
Fire classification DIN 4102 B1 (see artice SH0021 MH).
The shown fire classification refer exclusively to the acoustic foam chosen. With a few exceptions, the acoustic foam offered with fire classification DIN 4102 B1 or B2 is also certified including the self-adhesive equipment.
Please refer to the detailed listing of the corresponding fire classification in the corresponding technical product data sheet.

Format Options   
All aixFOAM products are available in different material thicknesses and the corresponding packing units.

Under “prices” we offer you the possibility acoustic heavy foam-lamination. With this option you receive a product that absorbs airborne sound as well as body-borne sound.

Application areas   
Machinery-encapsulations, engines, electrical devices, machine rooms, engine bays, sound insulating doors, compressors etc.
