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:

Product name	Manufacturing plant
Product name	Montevideo, MN, US
Patrick Covered Gypsum System	Product evaluated by the CCMC

Product evaluated by the CCMC Indicates that the product from this manufacturing facility has been evaluated by the CCMC

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 9.23.10.1., 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 S_a(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 9.23.17.2., Thickness, Rating and Material Standards, and fastened in accordance with Table 9.23.3.5.-A, of Division B of the NBC 2015.
- In locations where the seismic S_a(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 9.23.13.4., Braced Wall Bands, to 9.23.13.7., 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.

Notes:

Footnote 1

Control specimen: single layers of 12.7-mm gypsum board were fastened using 38-mm galvanized ringed wallboard nails every 200 mm o.c. at the edges and in-field. The framing was 38 mm × 89 mm SPF-grade wood studs at 406 mm o.c. spacing. The wall specimen was 2.4 m × 2.4 m.

Footnote 2

Patrick Covered Gypsum System specimen: the lauan plywood panel was fastened to the framing using 38-mm drywall nails. Structural adhesive was applied to the face of the lauan plywood panel in a serpentine pattern along all stud locations. The Patrick Covered Gypsum System sheathing was also fastened through the lauan plywood panel to the framing using 6.35 mm × 25.4 mm staples on the perimeter at 150 mm o.c. spacing and 600 mm at intermediate supports. The wall specimen was 2.4 m × 2.4 m.

Return to table footnote 2 referrer

Footnote 3

The deflection of the Patrick Covered Gypsum System does not exceed the control specimen deflection; therefore, it meets the requirements. See limitations in this evaluation for the installation requirements as per Subsection 9.23.13., Bracing to Resist Lateral Loads Due to Wind and Earthquake, of Division B of the NBC 2015.

Footnote 4

The control specimen failed prior to reaching the applied racking load. As a result, no deflection or residual deflection was recorded.

Code Compliance via Alternative Solutions

Where a design differs from the acceptable solutions in Division B, then it should be treated as an "alternative solution." A proponent of an alternative solution must demonstrate that the alternative solution addresses the same issues as the applicable acceptable solutions in Division B and their attributed objectives and functional statements. However, because the objectives and functional statements are entirely qualitative, demonstrating compliance with them in isolation is not possible. Therefore, Clause 1.2.1.1.(1)(b) identifies the principle that Division B establishes the quantitative performance targets that alternative solutions must meet. In many cases, these targets are not defined very precisely by the acceptable solutions [...] Nevertheless, Clause 1.2.1.1.(1)(b) makes it clear that an effort must be made to demonstrate that an alternative solution will perform as well as a design that would satisfy the applicable acceptable solutions in Division B—not “well enough” but “as well as.”

National Building Code of Canada, Sentence A-1.2.1.1.(1)(b)

The CCMC has determined that compliance with this provision of the Code has been demonstrated as an Alternative Solution. The evaluation report provides a summary of the basis of CCMC's compliance opinion.

CCMC's code compliance opinions

All CCMC evaluation reports are opinions of code compliance established in accordance with the National Building Code of Canada, Subsection 1.2.1. "Compliance with this Code," which requires compliance to be achieved by:

complying with the applicable acceptable solutions in Division B, or
using an alternative solution that will achieve at least the minimum level of performance required by Division B in the areas defined by the objective and functional statements attributed to the applicable acceptable solutions.

The CCMC assesses compliance with Canadian building, energy and safety codes, and is trusted by over 6,000 regulators across Canada.
