    400 Flashing, also known as 400, is modified asphalt bonded to a polyethylene sheet.  The primary uses are for wall flashing, through wall flashing (TWF), joint flashing, and non-vapor permeable air barrier.  The asphalt is protected with a release paper that is slit 3-inches in from an edge.  The slit establishes two sections of release paper that can be removed independently, thereby allowing the flashing to be placed and aligned on a wall without adhering the entire sheet until alignment is complete.  This installation method promotes asmooth interface with the substrate, increases installer productivity and reduces waste.  The split release paper is standard for sizes 6through 24-inches.
