Ontario Building Code
Ruling No. 10-16-253 (13378-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 2010-08-05 (revised 2017-03-22) 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.
- DecKorators® Composite Deck Board
- Marine Composite Deck Board
The products are solid deck boards intended for use as exterior decking installed over traditional structural wood framing (see Figure 1 and Figure 2). Comprised of a wood, thermoplastic composite made primarily from wood fibre, virgin and reclaimed polyethylene and talc, the boards are rectangular in shape with rounded corners and slotted edges.
The DecKorators boards are solid deck boards with rounded corners and/or slotted edges. The Marine boards are embossed with a wood grain finish on one side and a combed finish on the other.
The DecKorators boards have a cap made of high-density polyethylene (HDPE).
The DecKorators boards have an average thickness of 21.2 mm and an average width of 139 mm. The Marine boards have an average thickness of 31.75 mm and an average width of 138.18 mm.
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.
- When the products are installed in conjunction with traditional structural wood framing designed to carry the applicable loads, the products may be used as exterior decking and as stair treads in combustible constructions for light duty applications such as residential occupancies that fall within the scope of Part 9, Housing and Small Buildings, of the NBC 2010, or for light commercial applications within the scope of Part 4, Structural Design, of Division B of the NBC 2010.
- Slip-resistance strips shall be provided in accordance with Article 220.127.116.11, Finish for Treads and Landings, of Divisions B of the NBC 2010.
- The products must be installed in accordance with the manufacturer’s usage guidelines for the Canadian market and in accordance with the following limitations:
- The planks must be installed with supports spaced at no greater than 400 mm o.c. for DecKorators, and 600 mm o.c. for Marine.
- The products must be fastened to the wood joists with fasteners conforming to Article 18.104.22.168., Standards for Nails and Screws, of Division B of the NBC 2010. The fasteners must have a corrosion protection coating(1) or be made of stainless steel. The planks must be fastened with a minimum of two fasteners of 63.5 mm in length per support.
- The products can also be installed using a hidden plastic fastening system as supplied by the manufacturer.
- The products must be gapped end-to-end based on the length of the plank and the temperature at installation. The end-to-end gapping must be a minimum of 1.5 mm for every 11°C difference between the installation temperature and the hottest expected temperature. The width-to-width gapping must be 6 mm.
- The products are not to be considered equivalent to dimensional lumber.
- The products may be installed by a person familiar with the products installation guide.
- The products are permitted to be installed where decay and termite resistance protection is required as per Article 22.214.171.124., Termite and Decay Protection, of Division B of the NBC 2010.
- Where possible, the label or packaging of the products must be identified with the manufacturer’s name or logo and the phrase “CCMC 13378-R.”
