Expert Verdict — Reviewed by the SuperArbor Pro Desk
The 5.5 in width is a versatile casing and corner board size that works with standard 5-7 in lap exposure layouts. Keep the primer coat sealed promptly after install, follow gapping requirements at butt joints and above trim heads, and use two fasteners per stud line per the installation instructions. Step up to the 7.25 in or 9.25 in widths when you want deeper fascia or band trim.
Fiber cement dust is a respiratory irritant: cut outdoors with dust extraction or shears, wear a mask, eye protection and gloves.
