| By partition walls, we mean separating structures in the form of inner walls and walls that separate premises. For residential premises, the walls should be insulated to allow for privacy (and at the same time for better fire safety). However, in certain situations extra insulation is required in order to exclude heat/cold. The choice of insulation products that is offered is therefore a minimum regarding sound.
By sound class, we mean the sound insulation (R'w) that can be expected between the spaces where the separating structure is used. In order to achieve the stated value, the general structure and connections must be carried out in accordance with the outer layer and/or batten supplier's instructions. The class limits of insulation vary somewhat from country to country. The laboratory recorded measurements of the construction solutions below are at least 3 dB over the stated values. |
