Series 5900 Silicone Structural Glazed Curtain Wall Installation
“A-A” Section Through Splice
Attach splice sleeve to upper
mullion with shear block
V: Vertical Splice Applications
Vertical Splice Joints at SSG Verticals and Horizontals
A.) Splice should occur at the spandrel areas.
B.) Fabrication Note: Match drill the splice for shear block attachment.
C.) Splice Note: The vertical mullions that
are structurally glazed must be
spliced at the horizontal locations.
(All mullion splice locations must
be reviewed by a factory
engineer.)
D.) Where the head clearance is
insufficient to allow the top
mullions to be lifted over the
splice, a retractable splice will be
used. The splice is taped into the
top mullion and dropped to a stop
screw in the mullion below. Don’t
match drill the anchors until a
check of the expansion joints and
wall installation is made.
Note: All anchors must be fixed
before glazing begins.
Note: When the mullion splice is
shop installed into the lower
mullion, (2) fasteners will be
used in the standard locations
as shown.
