STEP 7) 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 center line 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 1/4" 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 66.
