    ARC Fire Stop Slab - Datasheet

    The ARC Fixing Spike is fitted to the external surface of the inner leaf. The ARC Fire Stop Slab is then impaled onto the spike. 

    A compression fit is not essential but it is required to have a snug fit within the cavity space, factory finished sizes are supplied with a 5mm compression fit. 

    Any site inaccuracies or deflection need to be sealed with a suitable intumescent sealer.

    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.
