  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 new cladding must be securely fastened as per the NBC 2015 requirements either
  1. directly through the existing structure; or
  2. attached to existing siding, if adequate rigidity and supports are provided and meeting the intent of Article 9.27.5.1., Attachment, of Division B of the NBC 2015.
  • The product may only be installed over existing cladding that has a minimum of 10 mm of air space behind it, which is vented to the exterior and drained. The vented and drained air space must be maintained after the new cladding is installed.
  • The product may be installed with or without a sheathing membrane. If no sheathing membrane is installed, and if the existing cladding is susceptible to moisture damage, then the joints of the product must be taped.
  • As stated in Note A-9.25.2.4.(3), Loose-Fill Insulation in Existing Wood-Frame Walls, of Division B of the NBC 2015, necessary steps must be taken prior to retrofit of the existing wall in order to lower the risk of moisture accumulation. Assessment of the existing wall configuration must be performed by an expert in building science prior to retrofitting.
  • The product shall be installed with suitable flashing as per Article 9.27.3.7., Flashing Materials, and Article 9.27.3.8., Flashing Installation, of Division B of the NBC 2015 to drain any incidental water from the existing drainage cavity to the exterior and to protect the exposed top edge of the cladding.
  • The product or its packaging must be clearly identified with the phrase “CCMC 14130-R.”

Explanatory information

The possibility of moisture accumulation within the wall construction is mainly a function of the physical properties of the insulation being installed and its impact on the thermal, air leakage and vapour diffusion characteristics of the existing wall. Consequently, the potential moisture accumulation resulting from the addition of insulation is very specific to the existing wall construction being retrofitted. This also applies to retrofit construction where insulating sheathing is installed over existing exterior walls.

Adding insulation as sheathing is beneficial only in cases where this insulative sheathing adds thermal resistance without increasing the risk of moisture accumulation. If installed properly, with knowledge of the existing wall configuration and performance, the product can provide additional thermal resistance to the wall assembly without any detrimental effects.

  Technical information

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
