The above opinion(s) is/are based on the evaluation by the CCMC of technical evidence provided by the evaluation holder, and is bound by the stated conditions and limitations. For the benefit of the user, a summary of the technical information that forms the basis of this evaluation has been included.
CANAROCK Lightweight Pre-Finished Insulated Panel System
The product is a hybrid, non-loadbearing, prefabricated, horizontally installed EIFS-type wall cladding that is manufactured in panel form under controlled factory conditions. The product consists of modular, prefinished expanded polystyrene (EPS) panels that are manufactured in-plant using proprietary extrusion techniques of the coating system.
The product has a tongue and groove design where the panels interlock (see Figures 1 to 5). The product consists of panels with lengths ranging from 1.2 m to 4.9 m and with widths ranging from 0.3 m to 0.7 m.
The product comes with several special accessories and mouldings for finishing the cladding system at edges, corners and interfaces.
The system includes CANAROCK PUCC insulation boards, which are Type 1 or Type 2 polystyrene foam insulation boards that are made from 100% virgin materials. They are manufactured and packaged by a CANAROCK-approved and QAI-certified manufacturer/moulder compliant with CAN/ULC-S701-11, “Thermal Insulation, Polystyrene, Boards and Pipe Covering.” The CANAROCK PUCC insulation boards have a geometrically defined drainage cavity (GDDC) design on one side of the EPS board that is made up of a series of circles (Pressure-Utilized Compartmented Cavity System - PUCCS), that are 86 mm in diameter, 10 mm deep and 16 mm apart, with an overall thickness of 63.5 mm (see Figure 2).
Synthetic coating system (lamina) and reinforcing mesh
A proprietary synthetic coating system (lamina) consisting of a base coat (Jewel Stone), a glass-fibre mesh and a finish coat (Gemstone) is applied over the smooth surface of the CANAROCK PUCC insulation boards through proprietary extrusion techniques under controlled factory conditions. The CANAROCK Fibre Mesh embedded in the coating system consists of an alkali-resistant, woven, glass-fibre reinforcing fabric that has a minimum nominal weight of 174 g/m2 (5.2 oz./yd.2).
Jewel Stone is a two-component base coat consisting of a dry-mix cementitious powder supplied in 22.7-kg bags and a wet mix polymeric admixture supplied in 19-L/19-kg pails. The material is mixed in a ratio of 4.5:1 (dry mix to wet mix) by weight. The uniform dry thickness of the base coat must not be less than 2.0 mm. The base coat must be sufficiently thick to fully embed the CANAROCK Fibre Mesh.
Gemstone is a proprietary, ready-mix, polymer-based finish coat that consists of coloured quartz aggregates in a clear polymeric resin. The thickness of the finish coat varies from 1 mm to 2 mm. The finish coat may also include metallic flakes intended for architectural purposes.
Note: The finish coat, base coat and mesh also form part of the PUCCS EIFS system in CCMC 12969-R.
The product is intended to be applied directly to vertical walls of brick, masonry, monolithic concrete walls, and/or cementitious, glass-mat surfaced gypsum, plywood or oriented strand board (OSB) sheathing boards installed over wood or steel framing. The product is available in an array of different colours and finish textures.
Water-resistive barrier (WRB) and adhesive
The panels are applied on-site over a water-resistive barrier (WRB), CANAROCK Polar Bear, that covers the full surface area of the intended substrates through an adhesive coatingTable footnote (1) . This application is similar to the PUCCS EIFS application in CCMC 12969-R. Mechanical fasteners are used to hold the panels in place while the adhesive coating cures.
CANAROCK Polar Bear is a factory-blended, ready-to-use, non-cementitious, polymeric, wet-mix coating supplied in 19-L/25-kg pails. It is intended for use on all types of substrates, including wood. Two coats of CANAROCK Polar Bear are applied over the substrate with a flat, stainless steel trowel. Each coat is applied in a continuous layer to achieve a minimum thickness of 1.2 mm per coat.
When it serves as an adhesive, CANAROCK Polar Bear is applied in a continuous layer with a flat, stainless steel trowel to achieve a minimum thickness of 1.2 mm.
The mechanical fasteners (used to install cladding while the adhesive cures) consist of corrosion-resistant anchoring screws and rectangular, low-profile, high-density polyvinyl chloride (PVC) washers that are used to secure the prefabricated CANAROCK elements. The spacing and frequency of the fasteners varies depending on the type of structural sheathing/substrate. The low-profile plastic washers, along with their fasteners, should be installed within the special grooves incorporated in the design of the panels.
The CANAROCK panels must be installed tight-fitting with tongue and groove joints. Venting at bottom of assembly is to be accomplished with 1 in.-wide weep holes at 8 ft.-0 in. o.c. above openings and at the bottom of the wall section, and sealing details as per the manufacturer’s installation instructions and by the CANAROCK-approved installers.

Thermal properties and effective R-value
- The effective R-value of the product, when installed as described in the Installation section of this evaluation, is equivalent to the thermal resistance of 50-mm-thick flat EPS insulation and it is in the order of RSI 1.3 (R7.38). Please refer to the Estimated thermal resistance (R-value) table of this evaluation for details.
- In cases the design professional uses the product on existing walls, the addition of thermal insulation onto existing exterior walls will increase the thermal efficiency and airtightness of the wall. However, deficiencies in flashing and other elements in the building assembly, including mechanical systems, may result in detrimental effects of moisture accumulation, as highlighted in Note A-126.96.36.199.(3), Loose-Fill Insulation in Existing Wood-Frame Walls, of Division B of the NBC 2015. As a result, once the EIFS (the product evaluated in this report) is installed, the existing exterior walls must meet the requirements of the NBC 2015 for heat transfer, air leakage and condensation control.
- The product can provide additional thermal insulation to the wall assembly with no detrimental effects if properly installed with knowledge of the existing wall configuration and performance.
- The product alone may not provide the full amount of the required wall insulation. The thermal resistance of the wall system must conform to the energy requirements of the applicable building code. The wall system may have to conform to the National Energy Code of Canada for Buildings 2015 at minimum to meet technical requirements of the Canada Mortgage and Housing Corporation (CMHC).
- The polystyrene thermal insulation boards must conform to the requirements of CAN/ULC-S701-11 as certified by QAI. The polystyrene thermal insulation boards must be cut from moulded blocks manufactured using 100% virgin raw materials. The polystyrene thermal insulation boards must be in conformance with the dimensional tolerances specified in Section B2.2 of CAN/ULC S 701.1-17, “Thermal Insulation, Polystyrene Boards,” which supersedes CAN/ULC-S701-11. The polystyrene thermal insulation blocks, prior to being cut into insulation boards for use in the product, must be aged in conformance with Section B2.2 of CAN/ULC S701.1-17, which supersedes CAN/ULC-S701-11.
