Face Cover Splicing
Splicing of the head and sill face covers can be accomplished at any place along the
horizontal span. Splicing of the intermediate horizontal face covers must be done at
the centerline of a vertical mullion. Ensure that the face cover end cuts are square,
clean of burrs or sharp edges, and clean of all cutting oils or other contaminants.
Space the face covers 1/2" apart at the required splice area. If necessary, use small
diameter backer rod to support the splice joint sealant. Fill the splice joint gap with a
silicone type sealant, and tool smooth to create a weather tight and cosmetic seal. See
Figure 111.
