    The ARC T-Barrier Masonry is easily installed as the brick and blockwork progresses. 

    No mechanical fixings are required, a friction fit within the external cavity and compression fit within the party wall cavity ensure the barrier stays in place. For runs of more than 1.2m, lengths of T-Barrier should be butted tightly together, with care taken to ensure there are no gaps.

    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.
