A cladding panel system comprises concrete panels having bevelled side edges , such that when the panels are installed on a supporting wall, the bevelled edges of adjacent panels form a V-joint with its apex at the rear surfaces of the panels. The bevelled edg es of adjacent panels provide a localized crush zone that absorbs thermal expansion stresses witho ut significant damage to the panels, thus eliminating the need for expansion joints. Flexible grou t such as urethane caulking is applied in the V joints between the panels to prevent entry of water. The panels are formed with perimeter caulking grooves to facilitate application of the flexible grout. The grout may have a coating such as silica sand for protection against ultraviolet radiation. Each panel includes hangar means, which may comprise one or more hangers embedded in the panel, for securing the panel to the supporting wall using screws or other common fasteners.
