beyond the bottom of the first level wall panel onto the
base rail at least one inch (see Detail C). Second level
ribbed Butyl tape (Item 6) starts at bottom of wall panel
on second level (see Detail B) and runs up to the top of
the second level wall panel.
2. Secure vertical seam cap (Item 7) over ribbed Butyl
tape (Item 6) with screws (Item 4) (see Detail A). First
level vertical seam cap (Item 7) starts at bottom of hem
on roof panels (see Detail B) and extends down onto
