Product description

Inteplast Deck, Wolf Serenity Deck, Inteplast Porch and Wolf Serenity Porch are exterior decking planks made of solid core foamed polyvinyl chloride (PVC) extrusions with a styrene copolymer cap layer. Inteplast Deck and Wolf Serenity Deck consist of solid profile (non-interlocking) decking boards that are 139.7 mm wide × 25.4 mm thick. Inteplast Porch and Wolf Serenity Porch consist of interlocking tongue and groove decking boards that are 79.0 mm wide (84.1 mm wide including tongue) × 25.4 mm thick. The products are available in 28 different colours.

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 o.c. Each plank must be supported by at least three joists.
  • The products must be fastened to the wood joists with fasteners specified by the manufacturer and that conform to Article 9.23.3.1., Standards for Nails and Screws, of Division B of the NBC 2015. The fasteners must have a corrosion-protection coating or be made of stainless steel.
    • Inteplast Deck and Wolf Serenity Deck planks must be fastened with at least two 63.5-mm-long fasteners per support;
    • Inteplast Porch and Wolf Serenity Porch interlocking (tongue-and-groove) starting planks must be fastened with at least two 63.5-mm-long fasteners: one vertical and the other with 30° to 45° angles off vertical at the tongue section; and
    • Inteplast Porch and Wolf Serenity Porch interlocking (tongue-and-groove) non-starting planks must be fastened with at least one 63.5-mm-long fastener at the tongue section with 30° to 45° angles off vertical.
    Note: As of January 2004, pressure-treated lumber requires specific hot-dipped galvanized fasteners for satisfactory performance.
  • Inteplast Deck and Wolf Serenity Deck (solid profile) gapping requirements:
    • The minimum width-to-width gapping must be 3 mm (0.12 in.) to 5 mm (0.18 in.); and
    • The minimum end-to-end gapping must be 3 mm (0.12 in.) for installations at 0°C to 24°C, and 5 mm (0.18 in.) for installations below 0°C.
  • Inteplast Porch and Wolf Serenity Porch (interlocking – tongue-and-groove) gapping requirements:
    • There is no width-to-width gapping for Inteplast Porch and Wolf Serenity Porch since they are interlocking (tongue-and-groove) decking systems.
    • The minimum end-to-end gapping must be 3 mm (0.12 in.).
    • Inteplast Porch and Wolf Serenity Porch (interlocking – tongue-and-groove) must not be installed at temperatures below 0°C.
  • Inteplast Deck and Wolf Serenity Deck (solid profile) can be used as stair treads at 230 mm (9 in.) o.c. spacing.
  • Inteplast Porch and Wolf Serenity Porch (interlocking – tongue-and-groove) cannot be used as stair treads.
  • The products have not been evaluated for applications where termite and decay protection is required as per Article 9.3.2.9., Termite and Decay Protection, of Division B of the NBC 2015.
  • 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 14121-R.”
