Anti-drumming heavy layers for metal sheets and metal parts
Heavy layers (or sound-deadening layers) are an excellent solution when it comes to insulating and attenuating the noise emitted by metal sheets or metal parts. They effectively minimize vibration, preventing the metal parts from drumming or booming. Other typical uses are interior linings in vehicles and sound-proofing enclosures or as part of noise-control covers. Its low thickness makes the heavy layer a perfect solution for applications where only little space is available.
You have the choice between our bitumen-based heavy layers soni HEAVY and soni HEAVY ALU, and our synthetic heavy layer soni EVA.

Heavy layers / sound-deadening layers
Heavy layers are highly suitable for insulating and attenuating the noise emitted by metal sheets and metal parts, since they effectively minimize vibration and thus prevent metal parts from drumming or booming. Heavy layers are also used as interior linings in vehicles or noise-insulation enclosures or for sound-proofing doors, windows, roller shutter casings or stairs. Thanks to their low thickness, heavy layers are a perfect solution for applications where only little space is available.
Heavy / sound-deadening layers provide the double effect of air-borne noise insulation and solid-borne noise attenuation.
soni EVA 3-01 is also used in composite products such as soni COMPOSITE, where it is combined with a PUR-ether acoustic foam laminated with a black non-woven surface layer. This ideal combination ensures a twofold noise-control effect: sound absorption plus sound insulation – for especially high overall effectiveness.
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.
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.
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.
