A vertical panel joint occurs between two concrete walls above the roof line. The joint features a half-inch gap centered on the panel centerline, with three-quarter-inch chamfered edges at the exterior face and sealant backed by a rod placed within the joint. The backside of the parapet has no chamfer from the ledger angle to above the roof flashing, and panel height must be confirmed with the roofer prior to forming.
