Heavy foils / anti-drumming layers

Heavy layers are highly suitable for insulating and attenuating the noise emitted by metal sheets and parts, or entire metal structures. As the heavy layer dampens vibrations and drumming, it prevents the propagation of sound waves and reduces noise emissions. Heavy layers are also used in vehicles, for soundproofing enclosures and covers and as well as for doors, windows, roller shutter boxes and stairs – to implement high-quality noise-control measures that are certain to achieve the desired noise reduction effect. Thanks to their low thickness, anti-drumming heavy layers are a perfect solution for applications where only little space is available. They are easy to cut to the required size and shape.
soni COMPOSITE
Color: black | Thickness: 32 mm
soni COMPOSITE is a combination product made from our synthetic soni EVA heavy layer and an acoustic foam laminated with a decorative felt layer. This ideal combination ensures a twofold noise-control effect: sound absorption plus sound insulation – for especially high overall effectiveness in reducing the noise level. soni COMPOSITE is particularly suitable for sound-transmission insulation. Mounted on the wall towards the neighbor’s apartment or behind a so-called curtail wall, for instance, our two-layer acoustic product achieves a noticeable noise reduction. For individual design options, you have the choice of various felt colors. Using a carpet knife, you can cut soni COMPOSITE to the required size and shape. The self-adhesive equipment of the rear face serves primarily as an installation aid.

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: 1.8 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.

soni SB 700
Our soni SB 700 sound-insulation panel is a two-layer product consisting of a highly sound-absorbing, hydrophobic polyester non-woven and a synthetic heavy layer (soni EVA 6-01). This newly developed combination has both sound-absorbing and sound-insulating capacity with especially high effectiveness in the frequency range of compressors. This makes it the optimum solution for substantially reducing the noise pollution caused by the compressors typically used in heat pumps or air-conditioning systems. In a few simple steps you can build a DIY compressor jacket from our soni SB 700 noise control panels. All you need to do is to measure the compressor’s dimensions and cut corresponding parts from the soni SB 700 acoustic panel with a carpet knife. Then fit the pieces like a shell around the compressor and seal the joints with soni VLC adhesive tape.  Our assembly instructions illustrate the three easy steps to building a compressor shell.

Applications for heavy layers


Heavy / sound-deadening layers deliver the double effect of air-borne noise insulation and solid-borne noise attenuation. Especially in areas where metal sheets or other materials tend to vibrate, the heavy layer does an excellent job. When glued onto the material, the heavy layer increases the mass or weight per area unit to an extent that usually leads to a rise in the so-called resonance frequency of the material. As a result, the unpleasant and often botheringly loud droning noise disappears. For this reason, heavy layers are mainly used as anti-drumming measure, which is why they are also called anti-drumming layers.

soni COMPOSITE combines the synthetic heavy layer soni EVA 3-01 with a robust PUR ether acoustic foam. The surface is covered with a non-woven that is available in 3 different colors. This ideal combination ensures a twofold noise-control effect: sound absorption plus sound insulation – for especially high overall effectiveness.  

Heavy layer products for various applications


The heavy layer products from soniflex can be used for sound insulation, sound-deadening and general noise-control purposes. This wide variety of application areas makes our heavy layer particularly versatile.  

Anti-drumming heavy layer for metal sheets and metal parts


Our anti-drumming layers are perfect for noise-insulating and damping metal parts and metal sheets. The use of self-adhesive layers prevents sheet metal from vibrating and droning, thereby minimizing the spread of noise events. The heavy layers are also suitable for use in vehicles or for lining sound insulation hoods and enclosures.

Bitumen-based heavy layer


soni HEAVY and soni HEAVY ALU are elastomer-modified bitumen-based heavy layers. In addition, they are provided with a self-adhesive finish on the reverse side, which makes them even easier to use. The bitumen-based heavy layer is used for damping and insulating metal parts and metal sheets or entire sheet metal structures.  

Synthetic heavy layer


If you are looking for a synthetic heavy layer, take a look at soni EVA from soniflex, a soft-elastic anti-drumming / heavy layer. It consists of a mixture of synthetic materials based on EPDM / EVA polymers blended with special flame-retardant minerals. Excellent insulating properties and a high level of fire safety make this product a convincing solution for many areas. Especially interesting: This heavy layer is very easy to install.
