Product information

Product name

Patrick Covered Gypsum System

Product description

The product is made from nominal 12.7-mm-thick gypsum board laminated with 0.1-mm-thick vinyl sheet on one side. The gypsum board is manufactured in accordance with ASTM C 1396/C 1396M-14, “Standard Specification for Gypsum Board.” The vinyl laminated gypsum board is stapled and adhered to a 4.7 mm lauan plywood panel, which is fastened to the wood stud framing.

Manufacturing plant

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

  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 orientation of the product must be installed parallel to framing. The framing must not be spaced more than 600 mm on centre (o.c.) and must comply with Table, Stud Size and Spacing, of Division B of the NBC 2015.
  • The fasteners for the lauan plywood panel must be installed at 150 mm o.c. around the perimeter and 300 mm o.c. at intermediate supports.
  • 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, and the adhesive must be installed on the lauan plywood panel at all stud locations. The staples must be minimum 19 gauge with a 6.35-mm crown and 25.4-mm leg. 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.”
  • The resistance to lateral loads of the product when used in braced wall applications is beyond the scope of the evaluation. Therefore, where braced wall paneling is required, the wall design must meet the NBC 2015 specific seismic resistance requirements without considering the contribution of the product.
    • In locations where the seismic Sa(0.2) is less than 0.70, and the 1-in-50 hourly wind pressure is less than 0.80 kPa (refer to Table C-2, Climatic Design Data for Selected Locations in Canada, and to Table C-3, Seismic Design Data for Selected Locations in Canada, in Appendix C of Division B of the NBC 2015 for locations of low-to-moderate wind and seismic zones), the exterior walls must be sheathed in accordance with 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 loads must be designed and constructed in accordance with Articles, Braced Wall Bands, to, Additional System Considerations, of Division B of the NBC 2015.
  • A vapour barrier must be installed as per Subsection 9.25.4., Vapour Barriers, 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 use of the product for the protection of foamed plastics is beyond the scope of the evaluation.
  • The use of the product in a fire separation is beyond the scope of the evaluation. 
  • The application of the product in walls around the bath and shower is beyond the scope of the evaluation.
