ULTRA BOARD is a lightweight structural panel consisting of a rigid polystyrene foam core faced on both sides by a smooth, moisture resistant sheet of solid polystyrene. The foam and facers are permanently bonded together. The face laminates have been specially developed to provide an excellent surface for painting, silk screening, photo mounting and vinyl lay up. Together with these properties and the ease and multitude of shaping methods make ULTRA BOARD an excellent choice for signage, photo mounting, exhibits, point of purchase displays and routed letters.
