Full length panels may be
installed up to curb location. All panel runs affected by curb must have
endlaps at downslope end of curb. Full length
panels cannot be field cut for curb locations because the beginning and
ending upslope panels will be 3" too short for the endlap.
Install all bottom panels, attaching back-up plates and Triple Bead tape
sealer to each panel as it is being installed. It
is critical that the tape sealer be installed across the pre-punched
holes and over the male leg of the panel before the next panel is
installed. Failure to follow this procedure will cause the
curb to leak during rains coupled with high winds.
Install curb on top of bottom panels and curb support framing.
Apply Triple Bead tape sealer to sides and upslope end of curb. Fasten
downslope end of curb to the bottom roof panels and back-up plates with
Fastener #1 E at 3 O.C. Fasteners must go through the tape sealer. |
