The above opinion(s) is/are based on the evaluation by the CCMC of technical evidence provided by the evaluation holder, and is bound by the stated conditions and limitations. For the benefit of the user, a summary of the technical information that forms the basis of this evaluation has been included.
Product nameAZEK Deck
AZEK Deck Harvest mono-extruded deck boards are made from foamed polyvinyl chloride (PVC) and cellulosic fibre with ultraviolet (UV)-resistant additives and colorants. AZEK Deck Arbor, Terra and Harvest co-extruded deck boards are made from PVC and proprietary mineral additives with UV-resistant additives and colorants. The composite products are manufactured through a continuous extrusion/coextrusion process into planks of solid cross-sections of varying thicknesses. Typical board dimensions are 140 mm wide by 25 mm thick.
The product is intended to be used as exterior decking to be installed over traditional structural wood framing.
This evaluation is limited to products produced at the following plants:

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 on centre (o.c.). Each plank must be supported by at least 3 joists.
- The product must be fastened to the wood joists with fasteners specified by the manufacturer and conforming to Article 184.108.40.206., Standards for Nails and Screws, of Division B of the NBC 2010. The fasteners must have a corrosion protection coating or be made of stainless steel. The planks must be fastened with at least two 57-mm-long fasteners per support. Footnote (1)
- The width-to-width gapping can vary from 3 mm (0.12 in.) to 6 mm (0.24 in.).
- The product can be used where termite protection is required as per Article 220.127.116.11., Termite and Decay Protection, of Division B of the NBC 2010.
- The product can be used as stair treads at 230 mm (9 in.) o.c. spacing.
- Slip-resistant strips shall be provided in accordance with Article 18.104.22.168, Finish for Treads and Landings, of Division B of the NBC 2010.
- The product is not to be considered as an equivalent to dimensional lumber.
