Product information

Product name

ZIP System^® R-sheathing

Product description

This evaluation addresses the performance of Huber Engineered Woods LLC’s proprietary ZIP System^® R-sheathing as insulating wood sheathing panels in lumber stud braced wall panel applications to resist lateral loads due to wind or earthquake.

Evaluation scope

This proprietary insulating sheathing results in the nail’s head being offset a distance from the lumber stud. This leads to a reduction in the lateral resistance of the braced wall. This evaluation provides proprietary design values for high wind and seismic loadings in accordance with Part 4, Structural Design, and alternative solutions for Part 9, Housing and Small Buildings, of Division B of the NBC 2015.

Product

ZIP System^® R-sheathing is a panel product that consists of an 11-mm (7/16-in.) OSB structural sheathing bonded to a sheathing membrane on one side and to a rigid foam insulation material on the other. It is installed with the foam insulation facing the studs. Hence, the nail heads are offset a distance from the lumber stud, separated by the wood-based sheathing and the thickness of the foam insulation. Figure 1 shows a typical installation of ZIP System^® R-sheathing. Note that this evaluation only covers the use of this product as insulating wood sheathing panels; its use for a sheathing membrane function is covered in CCMC 14019-R.

The wood-based structural sheathing component of this product is an 11-mm (7/16 in.) OSB panel complying with CSA 0325, "Construction Sheathing," for exterior wall applications for the requisite stud spacing. The OSB has an in-plant laminated sheathing membrane, which is a polymer-modified sheet overlay applied during OSB manufacturing process. The rigid foam insulation material component of this product is a polyisocyanurate insulation panel, ACFoam^®-III/Stucco-Shield^® II/Rboard^™ (CCMC 12423-L), which meets the requirements of CAN/ULC-S704-11, "Thermal Insulation, Polyurethane and Polyisocyanurate, Boards, Faced," as specified in the NBC 2015. The product is available with different thicknesses of rigid foam insulation, 12.7 mm (1/2 in.), 25.4 mm (1 in.), 38.1 mm (1 1/2 in.) and 50.8 mm (2 in.) as shown in Table 1. The sheet panel is available in normal 1 219 mm (4 ft.) in width and 2 438 mm (8 ft.), 2 743 mm (9 ft.), 3 048 mm (10 ft.), 3 353 mm (11 ft.), and 3 658 mm (12 ft.) in length.

Adhesive

The adhesive used to bond the wood-based panel and insulation was not being subjected to long-term testing and therefore is not part of this evaluation. However, the testing was also conducted with and without the adhesive and showed no impact on the structural test results.

Low permeance material

In addition, as the insulation plus the integral sheathing membrane OSB possesses a water vapour permeance of less than 60 ng/(Pa‧s‧m²), when measured in accordance with Procedure A (Desiccant Method) of ASTM E96M-13, “Water Vapor Transmission of Materials,” the ZIP System^® R-sheathing is a low air and water vapour permeance material installed on the cold side. As a result, the exterior wall assembly complies with Subsection 9.25.5., Properties and Position of Materials in the Building Envelope, of Division B of the NBC 2015 with respect to the outboard insulation in accordance with Table 9.25.5.2., Ratio of Outboard to Inboard Thermal Resistance, of Division B of the NBC 2015 for the respective heating degree-day (HDD) of the geographic location of the building using the RSI values in Table 1.

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.
