C-Block System is a highly efficiency noise-reduction designed for horizontal elements (ceilings). Depending from the level of noise-reduction, can be produced with thickness from 70 to 120 mm. Key elements of its effectiveness are the plates of technical polyurethane Decibel Visto 48, with specially designed geometry. The Visco’s elastic membrane ( Decibel Visco ) mounted between the high-density boards, extra enhances the sound insulation properties in the entire frequency spectrum. Suitable for medium to high levels of noise-reducing airborne noise, in some case is suitable against impact noise.
