These architectural section details show the head, sill, and jamb conditions for pre-finished louvres installed at exterior walls featuring brick veneer and metal cladding. A continuous metal angle frames the rough opening for attachment and self-adhered membrane upturn, sealed with backer rod and caulking between the louvre flange and the membrane. Pressure-treated wood blocking or an optional twenty-gauge galvanized sheet metal breakshape supports the double-layer nineteen-millimeter pressure-treated plywood sill. A loose structural lintel angle supports the brick masonry above the masonry condition, while a pre-finished metal flashing with a minimum fifty-millimeter end dam manages moisture below the sill. Mineral wool insulation and a UV plenum or duct connect to the interior mechanical systems.
