Code compliance opinion
It is the opinion of the Canadian Construction Materials Centre that “SRP AirOutshield™ – Sheathing Membrane,” when used as a breather-type sheathing membrane in accordance with the conditions and limitations stated in this evaluation, complies with the following Canadian code(s):
National Building Code of Canada 2015
|Code provision||Solution type|
|220.127.116.11. Sheathing Membrane Material Standard||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 which forms the basis of this evaluation has been included.
The product is manufactured by thermally bonding two spun-bonded polypropylene fabrics with a microporous film between the two layers to form a breathable waterproof membrane.
The product is 0.5 mm thick and has a white inner face and a black exterior. It is available in rolls that are 1.5 m wide and 50 m long.
This evaluation is valid only for products produced at the following plants:
- Bolton, United Kingdom
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 membrane 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 within 60 days from exposure to ultraviolet (UV) radiation from the sun;
- installed according to Article 18.104.22.168., Required Sheathing Membrane and Installation, of Division B of the NBC 2015, and in accordance with the manufacturer’s current instructions;
- installed with a minimum air space of 10 mm between the sheathing membrane and the cladding, unless the cladding does not require an air space (i.e., as deemed by the CCMC or by building officials based on past cladding performance); and
- installed with the material overlapping 100 mm at vertical joints and 100 mm at horizontal joints. Note that joints must be taped and the material must be sealed around both window and door openings.
- A concealed air space exceeding 25 mm in width must contain proper fire blocks 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 13549-R.”
This evaluation is based on demonstrated conformance with the following criteria:

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:
