Vertical acoustic fire-rated cavity stop and DPC.
The Acousdpc has been developed to offer vertical protection and complement the horizontal Acoustray and Acousformer systems in minimising flanking noise transmission along the cavity of an external cavity wall at the intersection of a party wall. It also operates fully as an effective fire barrier cavity stop and in conjunction with the polythene DPC has no risk of water penetration.
Where a party wall meets the cavity wall, Building Regulations stipulate the use of a mineral wool closer for sound insulation purposes. The NHBC requires that any such closer is protected by a suitable DPC. It has been developed to meet these requirements.
