Product information

Product name

Armadillo Composite Decking

Product description

The product is a wood thermoplastic composite lumber (WTCL) made primarily from equal parts of wood fibre and reclaimed/recycled high-density polyethylene (HDPE) with an ultraviolet-protectant capstock. The composite product is manufactured through a continuous extrusion process and formed into planks of solid cross-sections. The planks are manufactured in nominal dimensions of 32 mm × 140 mm and are available in 3.66 m, 4.88 m and 6.11 m lengths.

The product is intended to be used as exterior decking to be installed over traditional structural wood framing spaced at 300 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 products must be installed with supports spaced no greater than 300 mm on centre (o.c.). Each plank must be supported by at least three supports.
  • The products must be fastened to the wood joists with fasteners specified by the manufacturer that conform to Article 9.23.3.1., Standards for Nails and Screws, of Division B of the NBC 2015 and the NBC 2020. The fasteners must have a corrosion-resistant coating or be made of stainless steel.Footnote (1) The planks must be fastened with at least two 64-mm-long fasteners per support.
  • The product must not be installed under 4°C.
  • The products must be gapped end-to-end based on the length of the plank and the temperature at installation. The end-to-end gapping must be:
    • 4.8 mm for installations below 10°C,
    • 4.0 mm for installations between 10°C and 15°C,
    • 3.2 mm for installations between 15°C and 20°C,
    • 2.4 mm for installations above 20°C, and
    • if end use temperature is expected to be higher than 35°C, consult the manufacturer for gapping requirement.
  • The width-to-width gapping must be 3 mm for installations above 5°C and 6 mm for installations below 5°C.
  • The products can be used where termite protection is required as per Clause 9.3.2.9.(1)(b), of Division B of the NBC 2015 and the NBC 2020.
  • Armadillo Heritage boards can be used as stair treads at 230-mm o.c. spacing.
  • Slip-resistant strips must be provided in accordance with Article 9.8.9.6., Finish for Treads and Landings, of Division B of the NBC 2015 and the NBC 2020.
  • The products are not to be considered as an equivalent to dimensional lumber.
  • The products are permitted where decay resistance is required according to Clause 9.3.2.9.(3)(a), of Division B of the NBC 2015 and the NBC 2020.
