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).
