Key Features • Up to four hours fire integrity • Specified in semi-detached, apartments and major projects • Complies to Robust Detail Part E and Building Regulations • Available without flanges (CSS) or with flanges (TCB) • Can be manufactured to suit cavity widths up to 300mm
ARC Cavity Stop Socks and TCBs have been designed to restrict the spread of smoke and flames within external masonry and timber frame walls, and to further minimise the effect of flanking noise pollution at wall junctions. They are produced from low resin, non-combustible rockfibre mineral wool and are sleeved in 50 micron polythene for on-site weather protection.
Installation ARC Cavity Stop Socks and TCBs are designed to be compression fitted within the cavity and are easily installed both vertically and horizontally during construction. Care should be taken to ensure butt joints are tightly fitted to maintain fire integrity. The cavity barrier must fully fill the cavity from the inner to outer leaf and any cavity insulation must be cut back. When using ARC TCBs for timber frame construction, the flanges are fixed to the frame using clout nails at 150mm centres. In vertical applications, both flanges are fixed, in horizontal applications only the top flange should be fixed. At door and window openings it is recommended the horizontal barrier should overlap the vertical barrier to ensure a close butted fit can be achieved.
Fire Properties ARC Cavity Stop Socks and TCBs are manufactured using rockfibre mineral wool which achieves a fire classification of Euroclass A1 as defined in BS EN 13501-1. ARC Cavity Stop Socks and TCBs are tested at Warrington Fire Research and Chiltern International Fire, achieving up to four hours fire integrity with traditional masonry construction and up to one hour in a timber frame construction. These tests comply with BS 476: Part 20: 1987 and BSEN 1366-4: 2006, using the test method stated EGOLF TC2 N421 (fire resistance for cavity barriers). Warrington Fire Research certificate number: 169804 Chiltern International Fire certificate number: 10039
Storage and Packaging ARC Cavity Stop Socks and TCBs are supplied in polythene packs which are designed for transporting and protecting the products. It is not recommended that the packs are stored in direct sunlight as the polythene which encapsulates the barriers can be damaged. When storing the barriers for longer periods of time it is recommended the product should be stored indoors, or under cover.
