FLASHING
**************************************************************************
NOTE: Base, head and sill flashing details should
be shown on wall section on the drawings. To be
most effective, the flashing should extend through
the exterior face of the masonry veneer and turn
down to form a drip. If flashing is to extend
through the veneer, the last sentence of the
paragraph should be retained and the appropriate
portions of Section 07600 FLASHING AND SHEET METAL
shall be changed to reflect this type of flashing
installation. If, for esthetic reasons, it is
necessary to conceal the flashing, the last sentence
of the paragraph will be deleted.
**************************************************************************
Continuous flashing shall be provided at the bottom of the wall cavity just
above grade. Flashing shall also be provided above and below openings at
lintels and sills, at shelf angles, and as indicated on the drawings.
Flashing shall be as detailed and as specified in Section 07600 FLASHING
AND SHEET METAL. Flashing shall be lapped a minimum of 150 mm 6 inches at
joints and shall be sealed with a mastic as recommended by the flashing

lintel and shelf angle dimensions.
Bond pattern should be running bond unless there are
compelling architectural reasons to select another
