  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.
  • 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, Fasteners for Subflooring and for Sheathing, 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 System Considerations, of Division B of the NBC 2015.
  • The product must be installed in accordance with the manufacturer's installation instructions, dated 2021-11-10.
  • The staples for the vinyl laminated gypsum board must be installed at 150 mm o.c. around the perimeter. The staples must be minimum 18 gauge with a 6.35 mm crown and 25.4 mm leg.
  • 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.
  • Use of a single top plate is permitted only in accordance with the requirements of Sentence, Top Plates, of Division B of the NBC 2015. Note that racking load tests are based on framing with a double top plate for both the control specimen and the evaluated product.
