Code compliance opinion

It is the opinion of the Canadian Construction Materials Centre that “VipRoc vinyl laminated gypsum,” when used as an interior finish on walls for manufactured housing 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 Flame-Spread Rating of Interior SurfacesAcceptable Gypsum products shall conform to ...Alternative Maximum spacing of supports for gypsum b ...Alternative Spacing of NailsAlternative

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.

  Product information

Product description

The product is a 12.4-mm-thick gypsum board laminated with 4-mm-thick vinyl on one side. The gypsum board is manufactured in accordance with ASTM C 1396/C 1396M-14, "Standard Specification for Gypsum Board." 

Manufacturing plants

This evaluation is valid only for products produced at the following plants:

  • Calgary, Alberta, 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 intended to be used for the interior finish of exterior and interior walls of manufactured, single-family detached, one-storey houses only.
  • The product must be installed parallel to framing and include perpendicular let-in furring. The framing must not be spaced more than 600 mm on centre (o.c.) and must comply with Table, Size and Spacing of Studs, of Division B of the NBC 2015.
  • The staples for the vinyl laminated gypsum board must be installed at 150 mm o.c. around the perimeter and 600 mm o.c. at intermediate supports. The staples must be minimum 19 gauge with a 6.35 mm crown and 25.4 mm leg.
  • An air barrier system must be installed as per Subsection 9.25.3., Air Barrier Systems, of Division B of the NBC 2015.
  • The product must not be used to support insulation.
  • The product must not be used for the protection of foamed plastics.
  • The product must not be used where a fire separation is required.
  • The boards must be installed over furring or framing that complied with the requirements of the NBC 2015 using adhesive. The adhesive must be third-party or CCMC-evaluated to CAN/CGSB-71.25-M88, “Adhesives, for Bonding Drywall to Wood Framing and Metal Studs,” or ASTM C 557-03(2017), “Standard Specification for Adhesives for Fastening Gypsum Wallboard to Wood Framing.”
  • A vapour barrier must be installed as per Subsection 9.25.4., Vapour Barriers, of Division B of the NBC 2015
  • The product application in walls around baths and showers is beyond the scope of this evaluation.
  • The product must not be used by itself where braced wall panelling is required to meet specific seismic resistance requirements:
    • In locations where the seismic, Sa(0.2) is less than 0.70 or the 1-in-50 hourly wind pressure is less than 0.80 kPa (refer to Division B of NBC 2015 Table C-2 and C-3 in Appendix C for locations of low to moderate wind and seismic zones), the exterior walls must be sheathed with oriented strandboard (OSB) as per Article, Thickness, Rating and Material Standards, and fastened in accordance with Table, of Division B of the NBC 2015.
    • In locations where the seismic, Sa(0.2) is greater than 0.70 but not more than 1.8, and the 1-in-50 hourly wind pressure is less than 1.20 kPa (refer to Table C-2 and Table C-3 in Appendix C of Division B of the NBC 2015 for locations of high wind and seismic zones), bracing to resist lateral load must be designed and constructed in accordance with Article, Braced Wall Bands, to Article, Additional Considerations, of Division B of the NBC 2015.
  • When used as interior finishing of exterior walls, exterior wall sheathing must be installed in accordance with subsection 9.23.17, Wall Sheathing, of Division B of the NBC 2015.

Administrative information


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 NRC has evaluated the material, product, system or service described herein only for those characteristics stated herein. 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.
