Reglet flashing
Flashing - Type GF
Reglet flashings are normally used at the top of an External Walling Insulation system. The return is cut into the motar joint between a course of brickwork. This reduces the reliance on silicon sealants and therefore is suited to exposed locations.
They can be supplied with full depth welded or push in end caps, joint clips, and corners.
Wiki reference - A reglet is found on the exterior of a building along a masonry wall, chimney or parapet that meets the roof. It is a groove cut within a mortar joint that receives counter-flashing meant to cover surface flashing used to deflect water infiltration
