SECTION II: VERTICAL FRAME INSTALLATION CONT.
Splice joints should occur at spandrel areas (if possible).
Refer to approved shop drawings for actual locations.
Splice sleeves will be shop assembled in the top of the lower mullion.
GENERAL NOTE: The following details depicts a splice joint of 1/2".
The required joint width must be determined at the design stage and
shown on the approved shop drawings, on a job by job basis.
The actual width of this joint depends on the expected amount of
thermal movement plus the expected movement of the building structure.
Once a final check of expansion joint placement and mullion
position is made, the final match drilling of mullion through anchor
holes and sealing of the splice joint may be completed.
