Code compliance opinion
It is the opinion of the Canadian Construction Materials Centre that 205-02 Tuck® Contractors Sheathing Tape / DuPont™ Tyvek® Tape, when used as a sheathing tape in accordance with the conditions and limitations stated in this evaluation, complies with the following Canadian code(s):
National Building Code of Canada 2010
|Code provision||Solution type|
|184.108.40.206. Continuity of the Air Barrier System||Alternative|
|220.127.116.11. Installation of Vapour Barriers||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.
205-02 Tuck® Contractors Sheathing Tape consists of a biaxially oriented, red polypropylene backing that is coated with a clear acrylic pressure-sensitive adhesive. DuPont™ Tyvek® Tape consists of a biaxially oriented, white polypropylene backing that is also coated with a clear acrylic pressure-sensitive adhesive. Both are available in rolls 60 mm wide and 66 m long.
This evaluation is valid only for products produced at the following plants:
- Cornwall, Ontario, Canada
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 is permitted for taping butt joints in Tyvek® HomeWrap™ (see CCMC 12808-R) and Tyvek® HomeWrap™ – Air Barrier Material™ (see CCMC 12857-R). It is also permitted for use in new and existing residential construction, subject to the following conditions:
- the tape can be applied at temperatures as low as −10°C, but adhesion will increase with warmer temperatures; and
- the product shelf life is one year from the date of receipt by the retailer when stored under optimum conditions of 21°C and 50% relative humidity.
- The product must be installed in accordance with the manufacturer’s current instructions, which include the following recommendations:
- the surface to which the tape is applied should be dry and free of oil and other contamination; and
- to ensure satisfactory adhesion, the tape should be firmly pressed down onto the substrate after application.
- The product must be clearly identified with the phrase “CCMC 11955-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:
