It is the opinion of the Canadian Construction Materials Centre that the evaluated products, when used as breather-type sheathing membranes in accordance with the conditions and limitations stated in this evaluation, comply with the following codes:
National Building Code of Canada 2015
|ID||Code provision||Solution type|
|09-27-03-02-00-0-00||18.104.22.168. Sheathing Membrane Material Standard||Alternative|
National Building Code of Canada 2020
|ID||Code provision||Solution type|
|22.214.171.124.||126.96.36.199. Sheathing Membrane Material Standard||Alternative|
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.
- Sahara™ Evo Breathable Home & Building Wrap
- Sahara™ Excel Breathable Home & Building Wrap
Sahara™ Evo Breathable Home & Building Wrap is a synthetic membrane consisting of woven spun-bonded polypropylene scrim coated with a waterproof, breathable material. The product is 5.5 mil thick and white in colour. The product is available in rolls ranging in widths from 0.91 m to 3.05 m and in lengths from 30.5 m to 45.7 m.
Sahara™ Excel Breathable Home & Building Wrap is a synthetic membrane consisting of a non-woven spun-bonded polypropylene membrane sandwiching a waterproof, breathable material. The product is 16 mil thick and tan in colour. The product is available in rolls ranging in widths from 0.91 m to 3.05 m and in lengths from 30.5 m to 45.7 m.
The products resist the passage of bulk moisture while maintaining a high degree of moisture vapour permeability. The rolled material is applied over the exterior sheathing material so that it forms a continuous envelope, underneath the cladding system, around the entire building. The figure below illustrates the application of the product.
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 of the product is to create a continuous envelope around the occupied areas of residential or light commercial construction. Such continuity is achieved by overlapping the membrane per Article 188.8.131.52., Required Sheathing Membrane and Installation, of Division B of the NBC 2015 and NBC 2020 (joints must be lapped not less than 100 mm) or sealing the product either to itself (using CCMC-evaluated contractor sheathing tape) or to other construction materials (using an acoustical sealant). Where a CCMC-evaluated tape is required to provide continuity, its adhesion over the membrane must be validated. The membrane continuity at penetrations is beyond the scope of this evaluation and must be achieved according to the manufacturer's instructions.
- 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 184.108.40.206.;
- 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); and
- installed with the material overlapping 100 mm to 150 mm at vertical joints and 100 mm at horizontal joints. Note: Joints must be 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 and NBC 2020.
- The product must be clearly identified with the phrase "CCMC 14510-R."
