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 6.4-mm- and 9.5-mm-thick panels can be used as flooring underlay for resilient and wood (parquet and strip) floor finishes.
- The 9.5-mm-thick panel can be used as flooring underlay for ceramic tile application in residential dwellings where the supports are spaced no wider than 600 mm on centre (o.c.).
- The 6.4-mm-thick panel can be used as flooring underlay for ceramic tile application in residential dwellings where the supports are spaced no wider than 400 mm o.c.
- The subfloor must be installed in accordance with Subsection 9.23.15, Subflooring, of Division B of the NBC 2015.
- The panel must be installed in accordance with Subsection 9.30.2., Panel-Type Underlay, of Division B of the NBC 2015 and in accordance with the manufacturer’s installation instructions.
- The panel must not be used where the subfloor is expected to be exposed to high moisture conditions.
- The panel must not be used where the flooring is expected to be exposed to significant or frequent wetting, such as in showers, saunas or hot-tub decks.
- The product must be identified with the following information:
- manufacturer’s name or logo; and
- the phrase “CCMC 12525-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of the local AHJs, design professionals, and specifiers to confirm that the evaluation is current and has not been withdrawn or superseded by a later issue.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:
