Loud roller shutter noise: Find out what you can do about it

Our shutter impact protection soni SOFT-CLOSE consists of a closed-cell, cross-linked polyethylene foam. The self-adhesive foam strip is glued to the bottom edge of the shutter (armor end slat) and absorbs the impact when the shutter is closed.In addition, a small strip of soni SOFT-CLOSE can be glued on top of both stoppers so that when pulling the shutter up, the impact on the roller shutter box is cushioned.

soni EVA – Elastic heavy layer for sound and vibration insulation soni EVA is a soft, elastic heavy layer based on EPDM/EVA polymers with an admixture of flame-retardant minerals. It is ideal for technical applications, vehicle construction and mechanical engineering, where vibrations, rumbling and sound transmission need to be reduced. High-quality properties of soni EVA ✔ Vibration damping: Reduces the rumbling and vibration of metal and sheet metal structures. ✔ Sound insulation: Prevents the transmission of noise and ensures a quieter environment. ✔ Mechanical & self-adhesive: The self-adhesive backing serves as an installation aid, especially for horizontal surface mounting. For vertical or overhead mounting,     additional mechanical fastening is recommended. Areas of application for soni EVA soni EVA is a proven material for: ✔ Vehicles: doors, bonnets, boot, interior trim. ✔ Mechanical engineering: covers, metal structures, vibration protection plates. ✔ Technical applications: sound insulation in workshops, industrial plants, metal structures.

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.
