In 4 simple steps to your perfect acoustics:

*Material thickness

Different material thicknesses, profiles and types affect the efficiency of certain frequency ranges. The fact is that the thicker the material, the better the absorption effect, especially for low frequencies. On account of the high quality of the specifically developed acoustic core an efficient sound absorption is achieved even with low material thicknesses.

Depending on the application area you can adjust the absorption efficiency to your personal requirements by combining different material thicknesses and acoustic elements. Our team of experienced experts will be glad to support you with professional advice and planning.

*Acoustic heavy foil lamination

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: Our 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.

*Mounting options

Without mounting aid

You would like to attach or glue the acoustic elements yourself? Then select "None". Please note that a glue-free adhesive is used when gluing. However, we always recommend our self-adhesive equipment for gluing.

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 before bonding.

Assembly/Suspension Cassette without accessory

>You will receive your individual sound absorber framed by a high-quality assembly/suspension cassette made of anodised aluminium. The aixFOAM cassette can be used for horizontal, vertical or floating assembly.
/div>
Assembly/Suspension Cassette including aixFOAM oscillating plugs

You will receive your individual sound absorber framed by a high-quality assembly/suspension cassette made of anodised aluminium. aixFOAM oscillating plugs serve the professional spaced-erection of the aixFOAM flat-mounted- or pendant assembly cassettes. The spacing prevents the transmission of acoustic vibrations to the substrate (masonry). In addition, the efficiency of all aixFOAM absorbers in the lower range frequencies is enhanced in combination with the aixFOAM flat-mounted- or pendant assembly cassettes.

Assembly/Suspension Cassette with aixFOAM pendant system Style

The aixFOAM pendant system style serves the suspension of aixFOAM pendant assembly cassettes. By means of this pendant system, you have the possibility of suspending the aixFOAM sound absorber of your choice, in combination with the aixFOAM flat-mounted or pendant assembly cassettes, either horizontal suspended from a ceiling, or vertically from a side walling. The suspension cords have a maximum length of around 1000 mm, and can be individually shortened upon erection, so that the aixFOAM sound absorber can be optimally placed.

*Pack quantity Für die Auswahl der richtigen Menge an Schallabsorbern kann man keine pauschale Aussage treffen, denn diese ist von einer ganzen Reihe von Faktoren abhängig und damit sehr individuell. Generell empfehlen wir, bei der Schalldämpfung schrittweise vorzugehen. Bei leichtem Nachhall/ Lärm genügt es häufig bereits, ~ 10% der Wand- und Deckenflächen mit Schallabsorbern auszustatten. Bei erhöhtem Hall/ Lärm empfehlen wir etwa ~ 20% und bei starkem Nachhall/ Lärm bis zu ~ 30% der Raumoberfläche mit Schallschutz auszurüsten. Sollten Sie unsicher sein, beginnen Sie zunächst mit einer kleineren Menge Absorber und ergänzende Sie diese bei Bedarf. Das schont nicht nur Ihren Geldbeutel, sondern beugt auch einer „Überdämpfung“ und somit einer unangenehm künstlichen Akustik vor. Um zu ermitteln, welche Menge an Schallabsorbern für Ihre Anwendung angemessen ist, nutzen Sie unseren Mengenrechner oder wenden Sie sich direkt an unsere Fachplaner für eine kostenfreie Beratung.
