Code 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||126.96.36.199. Sheathing Membrane Material Standard||Alternative|
Ontario Building Code
Ruling No. 09-17-215 (12892-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 2009-08-12 (revised 2010-12-30) 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 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 that forms the basis of this evaluation has been included.
- Typar® CertaWrap™
- Typar® HouseWrap
The product is produced from a 100% polypropylene, spun-bonded olefin fabric made from oriented, isotactic polypropylene filaments that have been thermally bonded and coated with a copolymer film. The product resists the passage of water, but permits the passage of water vapour.
The product is light gray with a black backing. It is 0.30 mm thick and is available in different rolls ranging from 0.91 m to 3.05 m in width and 28.96 m to 60.96 m in length.
The roll material is applied over exterior sheathing material with the printed side out so that it forms a continuous envelope around the entire building.
This evaluation is valid only for products produced at the following plant:

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 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 188.8.131.52., 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); and
- installed with the material overlapping 75 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.
- The product must be clearly identified with the name of the manufacturer or logo and “CCMC 12892-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:

The information and opinions in this evaluation are directed to those who have the appropriate degree of experience to use and apply its contents (i.e., AHJs, design professionals and specifiers). This evaluation is only valid when the product is installed in strict compliance with the stated conditions and limitations of evaluation and the applicable local building code. In circumstances where no applicable local building permit is issued and that no confirmation of compliance ‘for use in the intended field application’ is undertaken, this evaluation is null and void in all respects. This evaluation is provided without representation, warranty, or guarantee of any kind, expressed, or implied, and the NRC provides no endorsement for any evaluated material, product, system or service described herein.
