This detail illustrates a masonry window head condition in an anchored stone veneer wall with a loose steel lintel angle. The lintel bears on the stone at the jambs of the window. The CMU is supported across the opening by a grouted, reinforced masonry lintel integral to the block. Continuous insulation offers excellent thermal control. An optional cavity drainage insert above the lintel protects the weep vents at the bottom of the cavity from becoming obstructed. The steel lintel is protected with thru-wall flashing returning vertically at each end to form an end dam. The durable drip edge guards against moisture reentry and may be notched to avoid excessively thick laps. The person using this detail shall be responsible for its complete design and proper application.
