FLEXIBLE INSULATING SHEET
The present invention is a twin-wall rigid plastic sheet intended to provide protection and insulation in applications where a small bending radius for the twin-wall plastic sheet is desired. The twin-wall configuration includes a smooth or flat outer single sheet and a contoured inner single sheet separated by a series of similar plastic ribs to form a connected row of longitudinal cavities or “channels”. The inner wall is contoured in a concave manner to form a relief between each rib. When the twin-wall sheet is flexed, each relief distorts to minimize stress in the transverse direction while maintaining high rigidity in the longitudinal direction. In another embodiment of the present invention, multiple single sheets separated by ribs and contoured similarly to that of the inner wall are added between the contoured inner wall and smooth outer wall.
