    ARC Party Wall DPC Datasheet

    ARC Party Wall DPC is designed to be installed as the brickwork and blockwork progresses, requiring only a friction fit within the cavity. No mechanical fixing is necessary.

    Horizontal Installations:
    As the brick and blockwork progresses, set the large flange of DPC in to the mortar between two courses of block (as shown overleaf). The height for this should be
    chosen so that the barrier sits against the edge of the floor, and the DPC is tight with no sags.

    ARC’s wealth of technical experience ensures that the best solution can be identified from their comprehensive range of products. All fire barriers and cavity closers are manufactured to NHBC requirements and hold LABC accreditation. Operating within an ISO 9001 Quality Management System and ISO 14001 Environmental Management System, all products are manufactured to the highest standards.
