Information: Preformed cavitray without an integral lead flashing attached. May be used as an alternative method of creating the damp course element only, where a sloping roof abuts a cavity masonry wall. This product is named Advantage, as it offers benefits not available from any other unleaded cavity tray manufacturer. The Advantage unleaded gable abutment cavitray is intended for use by installers who wish to introduce their own flashing medium at a later date. Each unit is moulded in solid DPC and has a variable cavity upstand facility. When incorporated within the external skin, the mortar is raked out underneath the base of the tray whilst it is still green. At a later date lead or other suitable flashing is cut and introduced within the raked out joint. Optional rake-out polystyrene front strip available.
