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.
