System and material comparisons
Fiber cement vs metal cladding
Fiber cement and metal cladding are common rainscreen faces. Compare impact behavior, finish, weight, fixing, joint treatment, coastal exposure and how each is repaired.
Fiber cement is a board made from cement, sand and cellulose fibers, usually factory-finished or painted on site. Metal cladding covers aluminum, steel or zinc panels and sheets, with various profiles and coatings. Both are used as the outer face of a ventilated wall on steel framing. The right choice depends on appearance, exposure, fixing system and how the product is maintained. See also the exterior cladding guide, fiber cement boards and insulated metal panels.
Comparison
| Factor | Fiber cement | Metal cladding |
|---|---|---|
| Weight | Heavier boards; more support | Lighter, depending on material and gauge |
| Impact and denting | Can chip or crack at edges; hard surface | Can dent depending on thickness |
| Cutting on site | Dust control and tools needed | Clean cuts, sharp edges, coating protection at cuts |
| Finish | Factory coatings or site painting | Factory coatings or natural metals |
| Expansion | Moisture and temperature movement in boards | Thermal expansion needs planned joints |
| Joint treatment | Open joints, flashing or sealed joints per system | Seams, clips and trims per system |
| Corrosion considerations | Fasteners and trim materials | Coating, dissimilar metals, cut edges |
Substructure and fixing
Cladding does not work alone. It sits on battens or rails fixed through insulation and sheathing to the framing. The fixing system must match the cladding weight and wind loads, and the substructure material should be compatible. Ask who designs it: the cladding supplier, the architect or the engineer. Review the envelope coordination guide to see how the layers fit together.
Water management
A ventilated rainscreen gap lets water drain and the wall dry. The water-resistive barrier behind the cladding is the real line of defense, and openings need flashings. Read about water-resistive barriers, flashing and the rainscreen principle. Cladding choice does not remove the need for good flashing.
Climate and exposure
For coastal, humid or industrial atmospheres, request exposure category information and the coating or finish warranty conditions. Dissimilar metals in contact can cause galvanic corrosion, so ask the supplier to check fixings, clips and trims. See corrosion protection and humid climate planning.
Fire and code
Exterior wall fire performance depends on the whole assembly including insulation and cavity barriers. Request the tested assembly or evaluation report and confirm acceptance with the local authority.
Maintenance and spare stock
Ask about cleaning, recoating, panel replacement and how long the product line will be available. Order a small spare quantity from the same batch, and record batch numbers so color matches later.

Questions people ask
Which suits coastal sites?
Both can be specified for coastal sites with proper products and fixings. Ask for exposure ratings and coating or finish warranties.
Which is heavier?
Fiber cement boards are generally heavier per area than thin metal panels, which affects support and fixing. Check datasheet weights.
Which is easier to repair?
Both can be repaired or replaced by panel, but matching finish and availability matter. Ask about spare stock.
Is either fireproof?
Fire behavior is stated in the product data and the assembly tests. Confirm with the local authority.
