Product description

The wall siding panels and corners are made of injection-molded, press-formed polypropylene and are fastened to the building structure with corrosion-resistant fasteners every 200 mm (8 in.) through pre-punched nailing slots located along the top edge of the panel, which are concealed once the upper panel is installed. The products and associated profiles evaluated under CCMC 13429-R are shown in Table 1. The products have a nail hem wall thickness of between 2 mm and 2.3 mm.
