Leaded preformed horizontal cavity tray system, including corner and stop end units, suitable for new build brick, block and stonework constructions. Featuring integral interlocking lapped joints to securely join cavity tray lengths together and create a watertight run which eliminates the requirement of additional tray jointing adhesives (taping etc) on site. Supplied with factory fitted lead flashing (long or short lengths), which presents a quicker and straightforward installation, as the cavity trays and flashings are installed in a single operation, rather than multiple trades, as well as a consistent protective and aesthetical finish. For external wall constructions not exceeding 102.5mm in thickness and clear cavity widths of between 50mm and 125mm • trays to suit clear cavity widths of 126mm+ are available to order. Available in two standard lengths, to allow build to standard brick bonding lengths for ease of use: • 4 standard brick length (900mm) for general use • 2 standard brick length (450mm) for making up a run to the required length. Preformed horizontal cavity trays provide protection from water penetrating the external wall leaf of a cavity wall down through to the internal wall leaf in specific vulnerable areas across the building such as: • the abutment of a flat, lean to or mono-pitched roof • over concrete ring beams • over building components that can act as a through cavity carrier such as air bricks, meter boxes, ducts and cavity liners. Also available unleaded and supplied with mortar barrier strips (to aid the installation of post fitted lead flashing). Preformed cavity tray systems are an effective method of DPC and present many benefits including reliability, speed of installation, reduced cold bridging opportunity and site waste.
