Product information

Product name

IPB Wall Panels

Product description

The product is an insulated wall panel system that is installed with two 2 × 6 lumber studs spaced at 1.2 m (4') on centre (o.c.) at panel edges with top and bottom plates. This is an alternate stud spacing to the 38 mm × 140 mm (2 × 6) framing at 600 mm (24") o.c. requirement specified in the NBC 2010. The insulated wall panel is an expanded polystyrene insulation board that is bonded with an adhesive to 11 mm (7/16") 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 (4') o.c. beyond the Code-specified 600 mm (24") o.c.

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

The two studs spaced at 1.2 m (4') o.c. are two 38 mm × 140 mm (2 × 6), S-dry S-P-F No.1/2. The panels that have been evaluated are 162 mm (6.4") thick with a maximum height of 3.04 m (10') and a standard width of 1.220 m (4'). The studs, continuous bottom plate and two top plates must be installed in the field as per the manufacturer's drawings for the CCMC-evaluated panel system. The qualified panels were tested with the electrical outlet cut-outs and 25 mm (1") chase within the foam core.

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

EPS core 

The panel core is a Type 1 EPS that is 140 mm (5.5") thick. The EPS insulation is certified by Intertek Testing Services (ITS) NA Ltd. (see CCMC 12424-L) to confirm compliance to CAN/ULC-S701, “Standard for Thermal Insulation, Polystyrene, Boards and Pipe Covering.”

OSB specification

The OSB is 11.1 mm (0.44") 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-E710, “Qualified OSB with low formaldehyde Emissions”, Tolko Industries, issued December 15, 2008. 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. Specifically, the MOR-AD™ M-647 manufactured by the Dow Chemical Co. (formerly Rohm and Haas Chemicals LLC) (see ICC-ES Report ESR-1023).

  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 2010. 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 2010.
  • The maximum number of storeys must be in accordance with Table 9.23.10.1. of Division B of the NBC 2010 for 38 mm × 140 mm (2 × 6) studs at 600 mm (24") o.c. for the respective thickness and alternate stud spacing of the proposed panels with two 38 mm × 140 mm studs at 1.2 m (4') o.c. spacing, specifically:
