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 intended to be used as a base sheet and ply sheet in B.U.R. systems.
- When the product is used in roof coverings installed on buildings governed by Part 3 of the NBC 2015, the roof covering must conform to a Class A, B or C classification determined in accordance with Article 188.8.131.52., Roof Covering Classification, of Division B of the NBC 2015.
- When the product is used as part of a rated roof assembly governed by Part 3, Part 5, and/or Part 9 of Division B of the NBC 2015, the roof assembly must be rated according to Articles 184.108.40.206., Determination of Ratings, and 220.127.116.11., Fire-Resistance and Fire-Protection Ratings, of Division B of the NBC 2015.
- A B.U.R. using the product must be constructed in accordance with Article 18.104.22.168. and Subsection 9.26.11., Built-Up Roofs, of Division B of the NBC 2015. The product surfaces must be mopped dry to avoid blistering.
- The product’s ply sheets are not watertight until totally saturated with hot asphalt. Exposed unfinished membranes must be kept dry and protected by an impermeable membrane until the product is fully covered with asphalt.
- This Evaluation Report is applicable only to products identified by the phrase “CCMC 12959-R.”

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of the local AHJs, design professionals, and specifiers to confirm that the evaluation is current and has not been withdrawn or superseded by a later issue.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:
