  • Fiberon®Symmetry™ Decking

Product description

The product is a wood thermoplastic composite lumber (WTCL) made primarily from equal parts of reclaimed hardwood sawdust and reclaimed/recycled high density polyethylene (HDPE) with specifically engineered UV-resistant additives and colourants. The composite product is manufactured through a continuous co-extrusion process in planks of solid cross-section with a HDPE-based capping material for additional stain, fade and scratch resistance. The planks are grooved or solid, are manufactured in nominal dimensions of 24 mm × 135 mm, and are available in 3.66m, 4.88m, and 6.1m lengths.

The product is intended to be used as exterior decking to be installed over traditional structural wood framing spaced at 400 mm on centre (o.c.) and stair treads spaced at 230 mm o.c.

  Conditions and limitations

The CCMC’s compliance opinion is bound by this product being used in accordance with the conditions and limitations set out below.

  • The product must be installed with supports spaced no greater than 400 mm o.c. Each plank must be supported by at least three supports.
  • The product must be fastened to the wood joists with fasteners specified by the manufacturer and conforming to Article 9.23.3.1., Standards for Nails and Screws, of Division B of the NBC 2010.
