Northernlite/Northernlite Cap Solid Decking Board

Product description

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.

Code Compliance via Alternative Solutions

Where a design differs from the acceptable solutions in Division B, then it should be treated as an "alternative solution." A proponent of an alternative solution must demonstrate that the alternative solution addresses the same issues as the applicable acceptable solutions in Division B and their attributed objectives and functional statements. However, because the objectives and functional statements are entirely qualitative, demonstrating compliance with them in isolation is not possible. Therefore, Clause 1.2.1.1.(1)(b) identifies the principle that Division B establishes the quantitative performance targets that alternative solutions must meet. In many cases, these targets are not defined very precisely by the acceptable solutions [...] Nevertheless, Clause 1.2.1.1.(1)(b) makes it clear that an effort must be made to demonstrate that an alternative solution will perform as well as a design that would satisfy the applicable acceptable solutions in Division B—not “well enough” but “as well as.”

National Building Code of Canada, Sentence A-1.2.1.1.(1)(b)

The CCMC has determined that compliance with this provision of the Code has been demonstrated as an Alternative Solution. The evaluation report provides a summary of the basis of CCMC's compliance opinion.

CCMC's code compliance opinions

All CCMC evaluation reports are opinions of code compliance established in accordance with the National Building Code of Canada, Subsection 1.2.1. "Compliance with this Code," which requires compliance to be achieved by:

complying with the applicable acceptable solutions in Division B, or
using an alternative solution that will achieve at least the minimum level of performance required by Division B in the areas defined by the objective and functional statements attributed to the applicable acceptable solutions.

The CCMC assesses compliance with Canadian building, energy and safety codes, and is trusted by over 6,000 regulators across Canada.
