Abstract: Washer assemblies for mounting panels to a support without damaging the panels include a countersunk washer and a sleeve. In one implementation, the washer assemblies are configured to at least partially prevent the formation of hoop stresses within a panel, and uniformly transmit forces created by a fastener to a panel. The washer assemblies can be configured to enhance the function, look, feel, or aesthetic of a panel system. In addition, systems of at least one implementation of the present invention include a plurality of panels mounted to one or more supports using one or more washer assemblies and methods of mounting such systems.

Abstract: A twisted resin panel includes resin material that has been heated and twisted after being subject to heat and/or pressure. In one implementation, a manufacturer can clamp opposing ends of a resin panel, such as a panel comprising a one or more layers thermoformed together. The manufacturer can then elevate the resin panel, and twist at least one end of the resin panel to achieve a desired aesthetic. Upper securing means (e.g., vertical clamps, rig hardware) at the upper end of the resin panel can be configured to move up or down during the twist of the resin panel in order to accommodate length variations thereof. Upon twisting, the resin panel will then cool into the desired position, and thus be used for any number of decorative architectural purposes. Implementations of the invention further include means to mount a twisted panel to upper and lower support surfaces.
