NOTE ** NOTE ** Parex Standard and Premium systems are PB systems, which is a class of EIFS where the base coat varies in thickness depending on the number of layers of reinforcing mesh, with a minimum thickness of 1/16 inch (1.5 mm). In PB systems, the reinforcing mesh is embedded into the base coat at the time of installation. Both Standard and Premium systems are available with a cementitious base coat or a synthetic base coat. NOTE ** NOTE ** Parex I-C Silver and I-C Gold systems are PM systems, which is a class of EIFS where the base coat is applied to a uniform thickness that can range from a nominal 1/4 inch (6 mm) to 3/8 inch (9 mm). Both the I-C Silver and the I-C Gold systems use a polymer modified base coat, but the I-C Gold system uses mechanical fasteners to secure extruded polystyrene insulation to substrate. A.
