Heavy foils / deadening foils

Heavy foil is mainly suitable for insulating and damping sheet metal and metal parts. It is used, for example, to prevent sheet metal or sheet metal structures from booming and thereby reduce noise. However, heavy foil is also used for lining in vehicles, in sound insulation hoods and for cladding as well as for doors, windows, roller shutter boxes and stairs in order to create high-quality and efficient sound insulation here. Due to its low thickness, the anti-drumming film can also be used where space is limited and can be cut to size individually.

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.

The use of heavy foil


Heavy foil or anti-drumming foil is particularly suitable where a product is needed for both airborne sound insulation and structure-borne sound insulation. Heavy foil does an excellent job especially where sheet metal or other materials are subject to vibration. The heavy foil is glued onto the material, increasing the mass or weight per unit area in such a way that the so-called resonant frequency of the material can increase, which means that the unpleasant and often loud droning noise also disappears. For this reason, the heavy foil is mainly used for anti-drumming, so that it is also called anti-drumming foil. 

In soni COMPOSITE, the plastic heavy foil soni EVA 3-01 is combined with a robust PUR ether acoustic foam with a black fleece surface. This optimum combination achieves both a sound-absorbing and sound-insulating effect, resulting in a particularly good overall result.


Heavy foil for various applications


The heavy foil from soniflex can be used for sound insulation, sound deadening and also for sound protection. Different areas of application make it particularly versatile.


Heavy foil for deadening metal parts and sheet metal


Our anti-drumming films are perfectly suited for the insulation and damping of metal parts and sheet metal. By using the self-adhesive elements, metal sheets are prevented from droning and vibrating, thus also preventing the propagation of sound. Furthermore, the foils are also suitable for lining vehicles and in sound insulation hoods as well as for cladding.

Bitumen heavy foil


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


Plastic heavy foil


In the area of plastic heavy foil, we offer our customers soni EVA, which is a soft-elastic anti-drumming foil or heavy foil. This consists of a plastic mixture based on EPDM / EVA polymers mixed with special flame-retardant minerals.  Excellent insulating properties and high fire safety make this product interesting for many areas. At the same time, this heavy foil is easy to apply.


Buy heavy foil at soniflex


If you want to equip sheet metal or sheet metal structures, roller shutter boxes, vehicles or other surfaces with a high-quality heavy foil, soniflex is the right place for you. We offer you high-quality heavy foils for structure-borne sound insulation and airborne sound insulation or for the deadening of materials. The self-adhesive films are particularly easy to use and efficient in their effect.
