Step sound board PAROC SSB 2t is non-combustible Stone wool insulation for use as a sound absorbing layer (spring) for the reduction of impact sound in floating floors. The fibre orientation in the step sound insulation slab is mainly horizontal compared to, for example, a roof slab or ground slab. The horizontal fibre direction gives a lower dynamic stiffness, which means better impact sound insulation. The compressive stress of the product is 40 kPa, which means that the slab can carry a 4000 kg/m2 load during installation and use. PAROC SSB 2t can be used both in concrete and Timber structures. The step sound insulation slab is faced with natural coloured Glass fibre tissue.
Please note that these product properties are not a replacement for the manufacturer's literature and it is always recommended that Paroc Panel System Oy Ab is consulted before specifying.
