Masonry to masonry ties act to secure two leaves of a cavity wall to each other, allowing them to act as one, structurally. A cavity tie usually incorporates some mechanism, (usually a change of shape) to discourage moisture moving across the tie. Most cavity ties are available with a dedicated clip to secure insulation (usually in sheet form) within the cavity. Timber fixing is used for fixing of timber joists, trusses and wall plates. It includes light & medium duty hangers & timber fixings, from standard joist hangers, to universal timber-to-timber hangers and truss clips. It is also available in straddle and return joist hangers.
