In a universal, reusable system for molding concrete or other settable fluids for use in building construction, an apertured composite plastic panel is provided for use in the framing system in which the plastic panel, rather than being of a honeycomb structure, includes a single face sheet which serves as a pour side surface, with an array of truncated pyramids having central apertures extending rearwardly from the back side of the sheet.
