Fiberon exterior cladding is a wood-plastic composite (WPC) board for use in rainscreen systems

Physical Features

Cladding Cutaway

  • Pre-finished boards made from durable wood-plastic composite with co-extruded, four-sided ®PermaTech cap layer that provides exceptional stain and fade resistance
  • Reversible boards work with horizontal, vertical, or diagonal applications
  • Ideal board-for-board replacement for 1x6 wood cladding
  • Works in open rainscreen applications in low-rise construction, in soffits, and screen facades
  • Dimensionally stable
  • Cladding boards available in 12 ft., 16 ft., and 20 ft. lengths
  • Nominal dimensions: .935 in. x 5.4 in.
  • Board Weight: 2.36 lbs./linear ft.
Color and Grain Pattern Options

Offered in two collections: Symmetry and Horizon

Symmetry Color Detail

  • Symmetry features a matte finish, subtle streaking, and four earthy colors: Burnt Umber, Cinnabar, Graphite, and Warm Sienna.


Horizon Color Detail

  • Horizon features a traditional wood finish, dramatic streaking, and four distinct shades: Ipe, Castle Gray, Rosewood, and Tudor Brown.


  • Contains 94% pre- and post-consumer recycled content (plastics and wood scraps) (WARNING: California Proposition 65 and Fiberon Products)
  • Contains no toxic chemicals or preservatives (unlike treated wood products)
  • Releases no carcinogens during cutting (unlike fiber-cement products)
  • Diverts 70,000+ tons of wood and plastics from landfills and incinerators each year
Product Performance

  • Access tech and testing docs, detail drawings, 3-Part Spec and more resources.
Fade Resistance


Ipe wood, shown here, requires regular cleaning or restaining

Ipe wood, in this example, will fade up to a 50 delta E in just two years. Therefore, the upkeep on wood (pressure washing, re-staining, etc.) doubles the cost of ownership every two to five years.

Fiberon cladding, on the other hand, experiences a minimal 5 delta E change after five years. A polymeric cap layer containing UV inhibitors, and non-reactive pigments, give Fiberon composite cladding outstanding color retention and resistance to fading.

Board Fastening
Starborn Deckfast Metal Photo1 Low Res

Fiberon Composite Cladding must be face fastened. Different fasteners result in varying aesthetics. Composite Deck Screws, which come in a variety of finishes, are recommended for best results. Coordinating colors virtually disappear, whereas a contrasting bright stainless steel adds a dramatic architectural effect. Please refer to Rainscreen Accessory Manufacturers for examples of fastener options.

We recommend using specially-coated fasteners or minimum 316 SS grade fasteners in areas in which salt water or salt spray could result in rust. High Velocity Hurricane Zones (HVHZ) require a minimum #9 x 2 ½” composite decking screw. Certain applications like metal framing may require screws with drill points.

Please see Cladding Installation Instructions for complete details.
