Ontario Building Code
Ruling No. 14-25-321 (13665-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 2014-10-27 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.
- Accuspan/Accuspan Cap Solid Grooved Board
- Northernlite/Northernlite Cap Solid Decking Board
The Accuspan/Accuspan Cap Solid Grooved Board and Northernlite/Northernlite Cap Solid Decking Board is a cellulosic/polymer composite decking made primarily of rice hulls and reclaimed/recycled high-density polyethylene (HDPE) with additives for UV resistance, anti-oxidants and colorants. The composite product is manufactured through a continuous extrusion process in planks of solid cross-section and grooved edges. The planks are manu- factured in nominal dimensions of 24 mm × 130 mm and are available in 3.6 m, 4.88 m and 6.1 m lengths. Both sides of the product are finished in a simulated wood grain pattern; either side can be used as a walking surface. The product is intended to be used as exterior deck boards and stair treads to be installed over traditional structural wood framing spaced at 300 mm on centre (o.c.) and on stair stringers spaced at 300 mm o.c.
The Accuspan Cap Solid Grooved Board and Northernlite Cap Solid Decking Board is the same composition as the Accuspan and Northernlite board with a cap stock incorporating UV inhibitors.
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 deck board must be installed with supports spaced no greater than 300 mm o.c.
- Each plank must be supported by at least three joists.
- The product must be fastened to the wood joists clips with fasteners specified by the manufacturer and conforming to Article 126.96.36.199., Standards for Nails and Screws, of Division B of the NBC 2010.
- The clips and fasteners must have a corrosion protection coating or be made of stainless steel.
- The clips must be fastened with a 64-mm-long fastener.
- The product can be used where termite protection is required.
- The product must be gapped end to end based on the length of the plank and the temperature at installation. The end-to-end gapping range must be between 4.2 mm for installations at a temperature below 7°C and 0.7 mm for installations at temperatures over 29°C.
- The width-to-width gapping must be 3 mm.
- The product can be used as stair treads on stringers spaced at 300 mm o.c.
- Slip-resistance strips shall be provided in accordance with Article 188.8.131.52, Finish for Treads and Landings, of Division B of the NBC 2015.
- The product is not to be considered as an equivalent to dimensional lumber.
