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.
