Product information

Product name

Ecopan Panels

Product description

The product is currently manufactured by three licensee plants: EnerSIP, EnerSmart and InGreen Systems.

The product is an insulated wall panel system that is installed with an alternate stud spacing to the NBC-specified 38 mm × 140 mm (2 × 6) framing at 600 mm (24 in.) on centre (o.c.). The product's panels are installed with 2 – 2 × 6 lumber studs spaced at 1.2 m o.c. located at the panel edges with top and bottom plates. The insulated wall panel foam core is an expanded polystyrene (EPS) insulation board that is bonded with an adhesive to 11-mm (7/16 in.) oriented strandboard (OSB) sheathings. The panels and studs form a unit stiffened by stressed-skin action, allowing for a wider stud spacing to 1.2 m beyond the Code-specified 600 mm o.c.

Typical details of the system are shown in Figure 1 and Figure 2.

The two field-installed studs, spaced at 1 220 mm o.c., must be 2 – 38 mm × 140 mm, S-dry Spruce-Pine-Fir (S-P-F) No. 1/2 or better. The panels that have been evaluated as equivalent to the requirements in Table 9.23.10.1., Size and Spacing of Studs, of Division B of the NBC 2015, for 38 mm × 140 mm (2 × 6) at 600 mm (24 in.) o.c., are 162 mm thick with standard heights of 2.4 m (8 ft) and 3.0 m (10 ft) and a standard width of 1 220 mm. The studs, continuous bottom plate and two top plates shall be installed in the field as per the licensee’s specific installation manual and drawings for the CCMC-evaluated panel system. The qualified panels had no electrical chases within the foam core.

Alternative panel configurations that may be offered by the manufacturer do not form part of this evaluation and shall not bear the CCMC number.

EPS core

The panel core is a Type 1 EPS that is 140 mm thick. The EPS insulation is certified by Intertek Testing Services (ITS) NA Ltd. (see CCMC 13393-L) to confirm compliance to CAN/ULC-S701-05, “Standard for Thermal Insulation, Polystyrene, Boards and Pipe Covering.”

OSB specification

The OSB is 11.1 mm thick, certified to CSA O325-07, “Construction Sheathing,” to a span rating of 1R24/2F16/W24. The OSB panels are certified by APA to CSA O325 and APA Product Report PR-N610, “Qualified OSB Facing Materials for Structural Insulated Panels,” revised August 22, 2011. The OSB is installed with the strong axis oriented vertically on both the interior and exterior surfaces of the panels.

Adhesive – EPS to OSB

The adhesive used to bond the EPS boards to the OSB panels is a moisture-cured urethane laminating adhesive. The adhesive is a designated MOR-AD^™ M-600 series adhesive, manufactured by the Dow Chemical Co. (formerly Rohm and Haas Chemicals LLC).

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 wall panel system is intended for dry service applications only.^{Footnote (1)}
The wall panel system is limited to buildings that fall within the scope of Part 9 of Division B of the NBC 2015. These panels are intended for buildings where combustible construction is permitted.
The wall panel system has not been evaluated to replace braced walls when required by Subsection 9.23.13., Bracing to Resist Lateral Loads Due to Wind and Earthquake, of Division B of the NBC 2015.

The number of storeys must be in accordance with Table 9.23.10.1., Size and Spacing of Studs, of Division B of the NBC 2015 for 38 mm × 140 mm studs at 600 mm o.c. for the respective thickness and alternate stud spacing of the proposed panels with 2 – 38 mm × 140 mm studs at 1.2 m o.c. spacing, specifically:

Disclaimer

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:

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.
