  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;
    • according to Article of Division B of the NBC 2015 and the manufacturer’s current instructions; and
    • with a minimum 10-mm air space between the sheathing membrane and the cladding, unless the cladding has been deemed not to require an air space (e.g., deemed by the CCMC or deemed by building officials based on past cladding performance).
  • CCMC-evaluated sheathing tape must be used to seal all joints.
