Evaluation Report CCMC 13690-R
AZEK Deck
1. Opinion
It is the opinion of the Canadian Construction Materials Centre (CCMC)that “AZEK Deck”,when used as exterior decking in accordance
with the conditions and limitations stated in Section 3 of this Report, complies with the National Building Code 2010:
•Clause 1.2.1.1.(1)(a), Division A, using the following acceptable solutions from Division B:
◦Article 9.4.2.2., Specified Snow Loads
◦Article 9.4.2.3., Platforms Subject to Snow and Occupancy Loads
◦Article 9.8.9.1., Loads on Stairs and Ramps
◦Article 9.8.9.6., Finish for Treads and Landings
•Clause 1.2.1.1.(1)(b),Division A,as an alternative solution that achieves at least the minimum level of performance required
by Division B in the areas defined by the objectives and functional statements attributed to the following applicable
acceptable solutions:
◦Article 9.3.2.9., Termite and Decay Protection
◦Article 9.4.2.1., Application
◦Article 9.4.3.1., Deflections
◦Article 9.8.9.3., Exterior Wood Steps
◦Article 9.23.15.5., Subfloor Thickness or Rating
This opinion is based on CCMC's evaluation of the technical evidence in Section 4 provided by the Report Holder.
2. Description
“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/co-
extrusion 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.

3. Conditions and Limitations
CCMC's compliance opinion in Section 1 is bound by the “AZEK Deck”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 three joists.
•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.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.
Note: As of January 2004, pressure-treated lumber requires specific hot-dipped galvanized fasteners for satisfactory performance.
•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 9.3.2.9. of Division B of the NBC 2010.
•The product can be used as stair treads at 230 mm (9 in.) o.c. spacing.
•The product is not to be considered as an equivalent to dimensional lumber.

The deflection results exceed the requirements. The additional deflection will not impact the overall performance.2Returntotable4.2.1footnote referrer
Deemed acceptable.Although this result (7.63 mm)exceeds the 2.0 mm requirement,the additional deflection is not considered
significant for material at 50°C. No failure after impact load and recovery was greater than 96%.
