Sandwich panels for especially effective noise control

Sandwich panels combine several layers for optimum acoustic effectiveness.
soni COMPOSITE is a combination of our soni DECOR – a robust PUR-based acoustic foam laminated with a black polyester non-woven – and our synthetic soni EVA 3-01 heavy layer. This combination provides soni COMPOSITE with very good noise control effectiveness in terms of both sound insulation and sound attenuation (= sound absorption). Its oil- and water-repellent and mechanically highly robust non-woven surface layer turns soni COMPOSITE into a universally suitable product for all applications that require a substantial reduction of the noise level plus efficient sound insulation.
The self-adhesive rear face ensures that the heavy layer stays fixed across the entire supporting surface for optimum noise attenuation results.
