ARC Party Wall DPC is designed to be installed as the brick and blockwork progresses, requiring only a friction fit within the cavity. No mechanical fixing is necessary.
The internal blockwork should be completed first. The ARC Party Wall DPC is then installed against this, with the brickwork being laid tight against the DPC, ensuring the barrier is tightly fitted with no gaps. The barrier should be oriented so that the 100mm lap of DPC is at the bottom of each length, this lap should run in front of the length below.
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.
