These "Filler" curtains are used to create more complete separation of work areas above Goff curtain packages, keeping virtually all contaminants out of unwanted areas. Custom manufactured to any size height and width, these valances are constructed of the same top quality 14 oz. or 20 mil. materials used in fabricating the original Curtain Walls. Grommets 1' O.C. along top and hook & loop fasteners at the bottom are options that make hanging your valance panels quick and easy.
