  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 product must be installed with the printed side facing outward and must be protected from exposure to ultraviolet (UV) radiation from the sun within 60 days of application to the wall.
  • The product must be installed in accordance with Article 9.27.3.3., Required Sheathing Membrane and Installation, of Division B of the NBC 2015 and the manufacturer's current instructions.
  • A minimum 10-mm air space must be ensured between the product and the cladding.
  • Any concealed air space exceeding 25 mm in width must contain proper fire blocking in accordance with Subsection 9.10.15., Spatial Separation Between Houses, of Division B of the NBC 2015.
  • The product must be covered with cladding that meets the material and installation requirements of the NBC 2015.
  • When the product is used as a re-siding underlayment over existing cladding:
    • all the conditions and limitations stated above apply, as the product also acts as a sheathing membrane;
    • the existing exterior walls being reclad with new cladding and the product must meet the requirements of the NBC 2015 for heat transfer, air leakage, and condensation control (see explanatory information below); and
    • the new cladding must be either securely fastened through the structure directly or attached to the existing siding if adequate rigidity and support are being provided.

 Explanatory information

The product may be used as re-siding underlayment provided it is properly installed with knowledge of the existing wall configuration and performance. The possibility of moisture accumulation within the wall construction is mainly a function of the physical properties of the additional materials being installed and their impact on the air leakage, vapour diffusion, and thermal characteristics of the existing wall. Consequently, the potential moisture accumulation resulting from the addition of materials is very specific to the existing wall construction being modified.

The product must be clearly identified with the manufacturer's name and logo, the product's brand name, and the phrase "CCMC 06666-R."

  Technical information

This evaluation is based on demonstrated conformance with the following criteria:

CCMC recognition

The Canadian Construction Materials Centre (CCMC) assesses compliance with Canadian building, energy and safety codes. We are the only construction code compliance service supported and operated by the Government of Canada. Trusted by over 6,000 regulators across Canada.

Most Canadian authorities having jurisdiction (AHJs) consider CCMC product assessments acceptable as evidence for product approval.

CCMC assessments are recognized by construction authorities across Canada:

The CCMC provides code compliance assessments to Canadian code requirements, consulting nationwide with construction regulators to elicit regional variations in code requirements as well as provincial and local interpretations. Users are advised to review the technical information presented in CCMC assessments when making approval decisions. Learn more about how the CCMC provides a unique service for Canada.

Code compliance as an acceptable solution

Code Compliance via Acceptable Solutions

If a building design (e.g. material, component, assembly or system) can be shown to meet all provisions of the applicable acceptable solutions in Division B (e.g. it complies with the applicable provisions of a referenced standard), it is deemed to have satisfied the objectives and functional statements linked to those provisions and thus to have complied with that part of the Code.

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

The CCMC has determined that compliance with this provision of the Code has been demonstrated as an Acceptable 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.

Code compliance as an alternative solution

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
