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.

soni EVA
Rear face: not self-adhesive (nk) | Thickness: 1.5 mm
soni EVA is a soft, elastic heavy layer on the basis of EPDM/EVA polymers with an admixture of flame-retardant minerals. Our soni EVA heavy layer is suitable specifically for technical applications, vehicles and machinery. It is designed to eliminate vibrations and drumming of sheet metal and metal parts. Applied to a metal structure, soni EVA will effectively reduce the sound level and prevent the transmission of noise and vibration. For soni EVA, the optional self-adhesive equipment of the rear face serves primarily as an installation aid. In the case of installation on a vertical surface or on a ceiling, we recommend additional mechanical fixation.

soni HEAVY
Thickness: 2.7 mm
soni HEAVY is a heavy layer made from elastomer-modified bitumen. Its surface is protected by a transparent polyester film. Our soni HEAVY anti-drumming layer is widely used for technical applications as well as in vehicles and machines. It is designed to eliminate vibrations and drumming of sheet metal and metal parts. As a heavy / sound-deadening layer, soni HEAVY delivers the double effect of air-borne noise insulation and solid-borne noise attenuation. The product scores with excellent insulation properties. The optional self-adhesive rear face facilitates the installation of the panels. In the case of installation on a vertical surface or on a ceiling, additional mechanical fixation is required.

soni HEAVY ALU
soni HEAVY ALU is a sound-deadening layer made from elastomer-modified bitumen with an aluminum surface. The heat-reflecting effect of the aluminum layer provides soni HEAVY ALU with a good fire safety classification. Our soni HEAVY ALU anti-drumming layer is predominantly used for technical applications as well as in vehicle and machine construction. Applied to a metal structure, soni HEAVY ALU will effectively reduce the sound level and prevent the transmission of noise and vibration. As a sound-deadening layer, soni HEAVY ALU delivers the double effect of air-borne noise insulation and solid-borne noise attenuation.   The self-adhesive rear face serves primarily as an installation aid. In the case of installation on a vertical surface or on a ceiling, additional mechanical fixation is required.

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.

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.
