To evacuate water from the system, weep notches must be placed at
the ends of each sill. This notch will manifest itself as a 1/8" X 1" notch
at each end of the sill, joining the vertical at the exterior face of the sill.
The notch also must remove the two extended legs in the middle
portion of the sill. These legs must be removed at the same height as
the face notch and requires that more material be removed. This
material removal will not be seen because it is under the sill and is
covered by the subsill. Refer to figures 7 and 8 below for notching
layout.
