For typical wall and millwork installations, a 4” wide batten strip of the same level material should be specified at the butt-joints to provide a minimal 2” overlap from one panel to the next, or each side of the joint.

The ArmorCore® batten strips can be attached directly to the panels and should be used where any vertical or horizontal joints occur. Battens are not required where a 90 degree corner occurs, in which case a panel should simply overlap to the next panel at the corner.
