Abstract

A panel assembly (40) that addresses oil canning when installed over a substrate or deck (72) is disclosed. The panel assembly (40) includes a panel (42). The panel (42) includes a first primary panel surface (44) that faces the substrate (72) in the installed configuration, as well as a second primary panel surface (46) that faces away from the substrate (72) in the installed configuration. Another component of the panel assembly (40) is a first structure (60) that is disposed between the panel (42) and the substrate (72). Typically, either a first surface (62) of the first structure (60) is chemically bonded directly to the first primary panel surface (44) such that an interface between the first surface (62) and the first primary panel surface (44) includes a chemical bond, or a second surface (64) is chemically bonded directly to the substrate (72) such that an interface between the second surface (64) and the substrate (72) includes a chemical bond. In any case, the first structure (60) produces a convexity on the second primary panel surface (46) to address oil-canning effects or stress wrinkling of the panel (42).
