Acoustic Party Wall DPC 557
Acoustic Party Wall DPC 557 has been developed to assist in reducing flanking sound transmission and prevent passage of flame within external masonry wall locations.
Acoustic Party Wall 557 is designed for use as a fire rated acoustic closer for party wall junctions. It helps reduce flanking sound transmission at the junction of internal separating and external cavity walls.
The Barrier is protected from moisture ingress by its integral DPC which must be installed with the DPC located to the rear of the outer masonry layer.
Acoustic Party Wall DPC 557 is intended for vertical application at party wall/external masonry wall junctions.
