A Band board is a decorative horizontal
trim used to break up the field of siding
on a building. Any width of HardieTrim
®
boards can be used for band board
depending on the type of detail desired.
If installing a band board, pay special
attention to flashing details and allow for
potential shrinkage of solid rim joists in
the walls that the band board may be
attached to.
Caulk between the underside of the
band board and the siding below. Do not
caulk between the flashing and siding
above the band board, and maintain a
1
/4-in. gap between the two. Also make
sure that the water-resistive barrier
laps over the flashing for a continuous
drainage plane. If running lap siding or

shingle siding above the band board, a starter strip should be installed first to maintain the correct siding angle. Small
Periodic gaps should be left in the starter strip to provide an escape route for excess moisture that may drain down
behind the siding.
Use bevel-cut splice joints of at least 22.5° to join long lengths of HardieTrim boards. To attach band board to the
building, drive two recommended fasteners every 16 in. for 4-in. and 6-in. boards. For 8-in. boards, use three fasteners
every 16 in., and use four fasteners every 16 in. for 12-in. boards.
