trim edges around windows and doors
only. Paint all cut ends.
• When installing trim around windows and
over window anges, be sure to follow
the window manufacturer's installation
instructions.
• All openings must be properly sealed
and ashed in a manner that prevents
moisture intrusion or buildup.
• Siding or trim applied adjacent to
porches, patios, walks, etc. must have
a clearance of at least 1" above any
surface.
• Flashing may be sealed to the water-
resistive barrier by using adhesive
ashing or housewrap tape. (See ALL
diagrams in middle column)
• The surface must be sloped or otherwise
designed to provide proper drainage so
the siding is at no time directly exposed
to standing water.
• Horizontal trim or bands shall be ashed
with a sloped metal Z-ashing to redirect
water away from the wall assembly.
