Product information

Product name

CANAROCK Lightweight Pre-Finished Insulated Panel System

Product description

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.

Insulation

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.

Substrate

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.

Fasteners

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.

Installation

 

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.
