Solid-borne sound

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.

soni HEAVY – Highly effective heavy bitumen layer for sound and vibration insulation soni HEAVY is an elastomer-modified heavy bitumen layer laminated with a transparent polyester film. This combination ensures a particularly robust, durable and sound-insulating surface – ideal for applications in vehicle construction, mechanical engineering and technical insulation. Thanks to its high density and material flexibility, soni HEAVY offers excellent sound insulation and effective vibration damping. It prevents metal surfaces from vibrating, booming and rattling, thereby specifically reducing sources of noise. Advantages of soni HEAVY at a glance ✔ Effective sound insulation & vibration damping → reduces both structure-borne and airborne noise ✔ High material density for maximum sound reduction ✔ Self-adhesive backing for easy installation ✔ Mechanically resilient & durable ✔ Can be combined with acoustic materials such as soni COMPOSITE or soni 491 STL ✔ Suitable for technical applications, vehicles and machinery Typical areas of application for soni HEAVY ✔ Vehicle construction: engine compartment insulation, door panels, floor panels ✔ Mechanical engineering: sound insulation for housings, bonnets, covers ✔ Enclosures & panelling: soundproofing of sheet metal and partition walls ✔ Building services engineering: insulation of heating systems, roller shutter boxes, ventilation ducts ✔ Combination with acoustic absorbers: for optimised sound insulation solutions Installation instructions for soni HEAVY The self-adhesive backing makes it easy to apply to smooth, clean and grease-free surfaces. However, for vertical or overhead installation, additional mechanical fastening (e.g. with pressure strips or screws) is required to ensure permanent secure adhesion.

Ordering acoustic panels from soniflex Our soni RESIST noise protection panel consists of closed-cell polyethylene foam with both sound-insulating and sound-absorbing properties. Its closed-cell structure makes soni RESIST especially suitable for applications where it may come into contact with moisture or humidity. The extremely robust and impact-resistant sound-insulation material does not constitute a medium for microorganism growth and can be wet-cleaned if necessary. soni RESIST is flame-retardant according to DIN 4102, as proven under B1 test conditions. Therefore the product is an excellent noise-control solution wherever you need to reduce the sound level with materials that meet strict fire safety regulations. Furthermore, soni RESIST ceiling and wall elements meet the ball impact resistance requirements of DIN 18032-3, making them ideal for noise reduction in sports halls and sports halls. The use of soni RESIST The optional self-adhesive rear face facilitates the installation of the panels. When mounted overhead or on uneven surfaces, (additional) mechanical fixation is required.
