Product information

Product names

  • AZEK Harvest
  • AZEK Vintage

Product description

AZEK Harvest and Vintage co-extruded deck boards are made of solid-core foamed polyvinyl chloride (PVC) with proprietary fillers and PVC alloy capping. Harvest co-extruded deck boards are semi-capped, while Vintage deck boards are fully capped. Typical board dimensions are 139.7 mm wide by 25.4 mm thick.

The products are intended to be used as exterior decking to be installed over traditional structural wood framing.

  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 400 mm on centre (o.c.). Each plank must be supported by at least 3 joists.
  • The products 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 2015 and the NBC 2020. The fasteners must have a corrosion protection coating or be made of stainless steel. The planks must be fastened with at least two No. 10 63.5-mm-long fasteners per support.Footnote (1)
  • The width-to-width gapping must be from 3 mm (0.12 in.) to 6 mm (0.24 in.).
  • The minimum end-to-end gapping requirements must be:
    • 1 mm between 0°C and 10°C, and
    • 1.5 mm for temperatures less than 0°C.
  • The products can be used as stair treads at 203 mm (8 in.) o.c. spacing.
  • The products have not been evaluated for applications where termite protection is required in accordance with Article 9.3.2.9., Termite and Decay Protection, 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 should be installed by a knowledgeable person familiar with the product installation guide.
  • The products’ label or packaging must be identified with the manufacturer’s name or logo and the phrase "CCMC 13690-R."
