soni COMPOSITE

Color: black | Thickness: 32 mm

soni COMPOSITE sound insulation mat – effective sound insulation and sound absorption in one product The soni COMPOSITE sound insulation mat from soniflex is a highly effective combination of sound insulation and sound absorption. This acoustic product consists of a heavy plastic film (soni EVA) and high-quality acoustic foam with a decorative felt surface. This intelligent combination of materials reduces both airborne and structure-borne noise, resulting in a noticeable reduction in noise levels – ideal for use in living spaces, offices, workshops or technical facilities. Double effect – sound absorption & sound insulation While the soni EVA heavy-duty film reliably reduces sound penetration, the open-pored acoustic foam layer absorbs the sound within the room. This dampens the noise at its source and prevents it from spreading – a real advantage over single-layer materials. Typical areas of application: ✔ Partition walls & neighbouring walls in flats and offices ✔ Machine cladding & engine rooms ✔ Workshops & technical rooms ✔ Suspended ceilings & drywall constructions ✔ Music rooms & recording studios Use of soni COMPOSITE – versatile & effective The soni COMPOSITE sound insulation mat is particularly suitable for soundproofing walls and ceilings. Installed, for example, on the wall separating you from your neighbours or behind a facing shell, the material significantly reduces disturbing noises and ensures pleasant room acoustics. Thanks to its decorative felt surface, soni COMPOSITE is available in a range of colours – ideal when function and design are equally important. Easy processing & secure installation Processing soni COMPOSITE is straightforward and does not require any special tools: ✔ The mat can be cut to size precisely using a craft knife or scissors. ✔ The self-adhesive backing serves as an installation aid – however, mechanical fastening (e.g. screws, press studs or strips) is recommended for permanent attachment, especially on vertical surfaces or for ceiling installation. ✔ Ensure that the substrate is dry, dust-free and smooth to ensure optimum adhesion. If necessary, you can cut soni COMPOSITE to the desired size with a craft knife. The self-adhesive backing serves as an installation aid. Tip: To create a clean finish at the joints, you can cover them with a wooden strip (8–10 cm wide) – this ensures a neat appearance and provides additional support. Safety & quality – tested for professional use soni COMPOSITE materials are age-resistant, moisture-resistant and free of fibres that are harmful to health. This makes this sound insulation mat a durable and safe solution for effective noise protection in both private and commercial areas.

PU foam at a glance: advantages, areas of application and practical tips

Acoustic foam – what is it?

Thanks to its open-cell structure and associated sound absorption function, soniflex acoustic foam achieves good acoustic improvements in reverberant and noisy rooms. Acoustic foam is used specifically to reduce reverberation or absorb sound in rooms.

Larger rooms with little furniture in particular tend to reflect sound. This means that telephone calls, machines, conversations between people and all kinds of noises can quickly become disruptive. Sound absorbers made of acoustic foam ensure intelligent, efficient and permanent absorption, eliminating echoes and noise disturbances. This is because polyurethane sound absorbers make it possible to slow down the individual vibrations of the air particles that are responsible for increased noise levels, thereby improving room acoustics.

Where is acoustic foam used?

Acoustic foam can be used anywhere: in a recording studio, a workshop, a production hall or even in private rooms. The possibilities are endless, as is the effectiveness of these sound absorbers. PUR foam sound absorbers are particularly popular in technical areas due to their robustness. Thanks to its dirt-resistant surface and high acoustic effectiveness, our soni WAVE, for example, is often used for enclosing machines. The polyurethane foam with its characteristic dimpled surface is easy to cut to size and impresses with its excellent absorption properties.

Typical applications for PUR acoustic foam
✔ In technical rooms
✔ In recording studios and music rehearsal rooms
✔ In recording studios
✔ In cars and engines
✔ In production halls to minimise machine noise
✔ In workshops
✔ In machine areas
✔ For compressors

The advantages of acoustic foam

Order acoustic foam online

At soniflex, we offer a wide range of different products in our acoustic foam category. Many of our foams are self-adhesive so that they can be installed as easily and simply as possible. Alternatively, non-self-adhesive acoustic panels can be attached using our soni SPECIAL ADHESIVE.

Polyurethane acoustic foam (DIN designation: PUR) is an anthracite-coloured, open-pored foam with very good sound-absorbing properties.

Our PUR foams impress with their softness, elasticity and good dimensional stability. These properties and their low weight make them a universally applicable sound absorber for a wide range of applications.

Their high temperature resistance and physiological safety make PUR acoustic foams high-quality and efficient sound absorbers.

Polyurethane soft foam can be easily cut with a cutter knife, fastened with screws or glued with our soni SPECIAL ADHESIVE (only suitable for non-self-adhesive panels).

Would you like to reduce the noise level? Then choose the high-quality acoustic panels from soniflex. If you have any questions about the individual sound absorbers or would like personalised advice, we look forward to hearing from you.

Installation

On request, nearly all our products can be delivered with self-adhesive rear faces, enabling easy, clean and time-saving installation – perfect for retrofit applications in rooms that are already in use.

Noise control

Thanks to their open-cell structure, our noise protection materials absorb sound waves and effectively attenuate bothering noise. A satisfactory result can already be achieved by lining 30 to 50 % of the ceiling and wall surfaces.

Fire protection

Many of our noise-control products are classified as flame-retardant according to DIN 4102 or DIN EN 13501. Please contact your local authorities in advance for information about the required fire protection class.
