Ontario Building Code
Ruling No. 08-13-198 (13191-R) authorizing the use of this product in Ontario, subject to the terms and conditions contained in the Ruling, was made by the Minister of Municipal Affairs and Housing on 2008-12-09 (revised 2009-11-30) pursuant to s.29 of the Building Code Act, 1992 (see Ruling for terms and conditions). This Ruling is subject to periodic revisions and updates.
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.
- MoistureShield® Vantage Decking
- MoistureShield® Vision Decking
The products are a wood thermoplastic composite lumber (WTCL) made primarily from equal parts of reclaimed oak hardwood sawdust and reclaimed/recycled polyethylene (HDPE). Both composite products are manufactured through a continuous extrusion process in planks of solid cross-section. The planks are manufactured in nominal dimensions of 25 mm × 137 mm and are available in 3.66 m, 4.88 m and 6.1 m lengths. MoistureShield Vision decking features an exclusive capstock for added fade and scratch resistance.
The products are intended to be used as exterior decking to be installed over traditional structural wood framing, spaced at 400 mm on centre (o.c.), with stair treads installed on stringers spaced at 230 mm o.c.
This evaluation is valid only for products produced at the following plant:

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 three supports.
- The products must be fastened to the wood joists with fasteners specified by the manufacturer that conform to Article 184.108.40.206., Standards for Nails and Screws, of Division B of the NBC 2015. The fasteners must have a corrosion-resistant coating or be made of stainless steel. The planks must be fastened with at least two 64-mm-long fasteners per support.Footnote (1)
- The products must not be installed under 5°C.
- The products must be gapped end-to-end based upon the length of the plank and the temperature at installation. The end-to-end gapping must be:
- 6.3 mm for installations below 10°C,
- 5.5 mm for installations between 10°C and 15°C,
- 4.7 mm for installations between 15°C and 20°C,
- 3.2 mm for installations above 20°C, and
- If end use temperature is expected to be higher than 35°C, consult the manufacturer for gaping requirement.
- The width-to-width gapping must be 5mm to 6mm.
- The products can be used as stair treads at 230 mm (9 in.) o.c. spacing.
- Slip-resistant strips shall be provided in accordance with Article 220.127.116.11, Finish for Treads and Landings, of Division B of the NBC 2015.
- The products are not to be considered as an equivalent to dimensional lumber.
- The products are permitted where decay resistance is required as per Sentence 18.104.22.168.(3)(a), of Division B of the NBC 2015.
- The products are permitted where termite resistance is required, as per Sentence 22.214.171.124.(1)(b), of Division B of the NBC 2015.
This evaluation is based on demonstrated conformance with the following criteria:
