James Hardie Smooth Soffit is a 1/4 in. fiber cement soffit panel for enclosing the eaves of your home. Choose from solid or vented profiles in 12 in., 16 in. and 24 in. widths and 8 ft. or 12 ft. lengths, in HZ5 and HZ10 ColorPlus and primed finishes.

Key Features:

• Eave Protection: Hardie Soffit panels help protect the vulnerable gap under the eaves from fire and moisture damage.
• Attic Airflow: Vented soffit options are a key tool for controlling attic airflow, helping keep the home cool in summer and reducing moisture accumulation in winter.
• Noncombustible: The panels are noncombustible fiber cement and will not burn, and enclosing eaves with noncombustible soffit is recommended to improve wildfire resilience.
• Climate Engineered: Formulated for regional climate needs, with HZ5 engineered for freezing temperatures, extreme temperature variations, hail, snow, ice and wet weather.
• Pest Resistant: Resists damage from woodpeckers, termites and other pests that can attack wood soffits.
• Wood Look: Smooth finish mimics the appearance of real wood with less maintenance.
• Storm Tough: Built to withstand weather extremes, hurricanes, winter storms and more.

Coverage & How Much You Need:

One panel covers its width times length; for example a 16 in. x 12 ft. panel covers 16 sq. ft. of eave, and a 24 in. x 8 ft. panel covers 16 sq. ft. Measure total eave length and select panel width to match framing, using vented panels where attic ventilation is needed.

Fit and Compatibility:

Part of the James Hardie fiber cement siding and trim system; use with Hardie trim, fasteners and color-matched accessories sold separately. Match the HZ5 or HZ10 climate zone rating to your region.

Expert Verdict — Reviewed by the SuperArbor Pro Desk

Match the panel width to your eave framing so fastener spacing falls on solid blocking, and use vented profiles along eaves that feed intake ventilation. For snowy or wet climates choose an HZ5-rated color, while HZ10 suits drier, hotter regions. Order trim and fasteners at the same time, and handle panels with care since fiber cement edges can chip if bumped.

Fiber cement dust contains silica; cut outdoors with a dust-reducing saw or shears and wear a respirator, eye protection and gloves.
