01.070.062D: Window Details | Adhered Brick Veneer, CMU Backing
This detail sheet contains a series of 2D details of a window sill, jamb, and head in an adhered veneer wall with CMU backing. A transition membrane wraps the wood blocking around the window perimeter, engaging with the air/moisture/vapor barrier in the field of the wall providing continuous resistance to air and moisture. Continuous insulation offers excellent thermal control. A drainage mat collects moisture that may penetrate the veneer and diverts it out through the weep vents at the sill and head via flashing with end dams. Self-furring lath is screwed through the drainage and insulation into the CMU with approved fasteners at required spacing and is embedded in the scratch coat. Casing beads engage with the lath to form terminations and brick expansion joints as required. The thin brick veneer and stone sill are adhered to the scratch coat with a modified bonding mortar per design.
