Code compliance opinion

It is the opinion of the Canadian Construction Materials Centre that the evaluated product, when used as a breather-type sheathing membrane under commonly used types of exterior cladding (except stucco) and brick veneer in accordance with the conditions and limitations stated in this evaluation, complies with the following code:

National Building Code of Canada 2015

ID	Code provision	Solution type
09-27-03-02-00-0-00	9.27.3.2. Sheathing Membrane Material Standard	Alternative
09-27-03-03-00-0-00	9.27.3.3. Required Sheathing Membrane and Installation	Alternative

The above opinion is 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.

Manufacturing plant

This evaluation is valid only for products produced at the following plant:

Product name	Manufacturing plant
Product name	Glasgow, KY, US
Fome-Cor^® Board	Product evaluated by the CCMC

Product evaluated by the CCMC Indicates that the product from this manufacturing facility has been evaluated by the CCMC

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.

Sheathing membrane – new construction
- The product must be installed with the printed side facing outward and must be protected from exposure to ultraviolet radiation (UV) from the sun within 60 days after application to the wall.
- The product must be installed in accordance with Article 9.27.3.3. of Division B of the NBC 2015 and the manufacturer’s current instructions.
- The product must be installed with a minimum 10 mm air space between the sheathing membrane 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.
Re-siding underlayment – retrofit
- The product may also be used as a re-siding underlayment over existing cladding. Existing exterior walls being reclad with new siding and the product as an underlayment must be retrofitted to meet the requirements of the NBC 2015 for heat transfer, air leakage and condensation control (see Explanatory information below).
- When the product is used as a re-siding underlayment, the product must be covered with new cladding that meets the requirements of the NBC 2015. 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.
- When the product is used as a re-siding underlayment, it also acts as a sheathing membrane. Thus, the installation requirements for sheathing membranes outlined above also apply to re-siding underlayment installations.
Explanatory information
- 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 retrofitted.
- The product may be used as re-siding underlayment provided it is properly installed with knowledge of the existing wall configuration and performance.
- The product must be clearly identified with the manufacturer’s name and logo, the product’s brand name and the phrase “CCMC 06666-R.”

Administrative information

Disclaimer

This evaluation is issued by the Canadian Construction Materials Centre (CCMC), a part of the Construction Research Centre at the National Research Council of Canada (NRC). The evaluation must be read in the context of the entire CCMC Registry of Product Assessments and the legislated applicable building code in effect.

The CCMC was established in 1988 on behalf of the applicable regulator (i.e., the provinces and territories) to ensure—through assessment—conformity of alternative and acceptable solutions to regional building codes as determined by the local authority having jurisdiction (AHJ) as part of the issuance of a building permit.

It is the responsibility of the local AHJs, design professionals, and specifiers to confirm that the evaluation is current and has not been withdrawn or superseded by a later issue. Please refer to the website or contact:

The NRC has evaluated the material, product, system or service described herein only for those characteristics stated herein. The information and opinions in this evaluation are directed to those who have the appropriate degree of experience to use and apply its contents (i.e., AHJs, design professionals and specifiers). This evaluation is only valid when the product is installed in strict compliance with the stated conditions and limitations of evaluation and the applicable local building code. In circumstances where no applicable local building permit is issued and that no confirmation of compliance ‘for use in the intended field application’ is undertaken, this evaluation is null and void in all respects. This evaluation is provided without representation, warranty, or guarantee of any kind, expressed, or implied, and the NRC provides no endorsement for any evaluated material, product, system or service described herein. The NRC accepts no responsibility whatsoever arising in any way from any and all use and reliance on the information contained in this evaluation with respect to its compliance to the referenced code(s) and standard(s).

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.
