1. Opinion

It is the opinion of the Canadian Construction Materials Centre (CCMC) that “Shield™ Air Barrier”, when used as a breather-type sheathing membrane in accordance with the conditions and limitations stated in Section 3 of this Report, complies with the National Building Code 2010:

  • Clause 1.2.1.1.(1)(b), Division A, as an alternative solution that achieves at least the minimum level of performance required by Division B in the areas defined by the objectives and functional statements attributed to the following applicable acceptable solutions:
    • Article 9.27.3.2. Sheathing Membrane Material Standard

This opinion is based on CCMC's evaluation of the technical evidence in Section 4 provided by the Report Holder.

2. Description

The product is available in white, yellow or grey and is made of a non-woven polyolefin base and a vapour-permeable laminated coating.

The product is 0.44 mm thick and is available in rolls ranging from 0.90 m to 3.05 m in width and 30 m to 59 m in length.

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

3. Conditions and Limitations

CCMC's compliance opinion in Section 1 is bound by the “Shield™ Air Barrier” 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. Continuity is achieved by overlapping or sealing the product either to itself using 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 2010 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 CCMC or by building officials based on past cladding performance); and
    • installed with the material overlapping 75 mm to 150 mm at vertical joints and 100 mm at horizontal joints.
  • A concealed air space exceeding 25 mm in width must contain proper fire stopping in accordance with Subsection 9.10.16., Fire Blocks, of Division B of the NBC 2010.
  • The product must be clearly identified with the phrase “CCMC xxxxx-R.”

4. Technical Evidence
