Profile: Mapes Panels, LLC offers insulated spandrel glass, curtain walls, window replacement, door sidelights, metal spandrel panels and passive solar control systems. Mapes-R panels offer a wide variety of solutions to improve the thermal efficiency of window, spandrel, curtain wall and glazing applications. We can manufacture to match any architectural finish including anodized, porcelain, and baked enamel. In addition to thermal improvement, our panels can meet local building codes for sound, fire and impact resistance. Our formed edge panels have formed edges that can be glazed into standard 1 inches glazing channels with panel thicknesses up to 4 inches. The panels are designed to create a flush appearance with the wall surface and framing. Butt joint panels are also available to eliminate exterior mullions in some spandrel, curtain wall and window applications. Formed corner panels can eliminate the need for framing or molding at corner transitions.
