Compliance opinion

It is the opinion of the Canadian Construction Materials Centre that the evaluated products, when used as a breather-type sheathing membrane in accordance with the conditions and limitations stated in this evaluation, comply 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

Ontario Building Code

Ruling No. 95-07-26 (12264-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 1995-09-21 (revised 2017-01-30) 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.

Air-Gard®
Weathermate™

Product description

The product consists of a micro-perforated woven fabric made of high-density polyethylene that is coated with a white-pigmented low-density polyethylene on one side and a natural, non-pigmented low-density polyethylene on the other side. The product resists the passage of water, but permits the passage of water vapour.

The product is 0.25 mm thick and is available in rolls in widths ranging from 0.94 m to 2.82 m and in lengths ranging from 33.8 m to 59.4 m. The colour of the product is white.

The rolled material is applied over exterior sheathing material so that it forms a continuous envelope around the entire building.

Manufacturing plant

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

Product names	North Bay, ON, CA
Air-Gard®	Product evaluated by the CCMC
Weathermate™	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.

The product can be used as a breather-type sheathing membrane under commonly used types of exterior cladding to reduce the risk of water infiltration. The main purpose is to create a continuous envelope around the occupied areas of residential or light commercial construction. Such continuity is achieved by overlapping or sealing the product either to itself, using the CCMC-evaluated contractor sheathing tape, or to other construction materials using an acoustical sealant.
A conforming installation must be:
- installed with the printed side facing outward;
- protected from exposure to ultraviolet (UV) radiation from the sun within 60 days;
- installed according to Article 9.27.3.3., Required Sheathing Membrane and Installation, of Division B of the NBC 2015 and the manufacturer’s current instructions;
- installed with a minimum 10-mm air space between the sheathing membrane and the cladding, unless the cladding has been deemed to not require an air space (i.e., deemed by the CCMC or by building officials based on past cladding performance);
- installed with the material overlapping 100 mm to 150 mm at vertical joints, and 100 mm at horizontal joints; and
- installed with joints taped and sealed around both window and door openings.
A concealed air space exceeding 25 mm in width must contain proper fire blocking in accordance with Subsection 9.10.16., Fire Blocks, of Division B of the NBC 2015.
The product must be clearly identified with the phrase “CCMC 12264-R.”

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.
