ALUSION™ - LARGE CELL AL-12.7-LG-2S - Open Both Sides (Translucent) The shiny silver skin on both sides of this low density material is removed to create a translucent panel. This panel is extremely lightweight and allows light to pass through. All Alusion™ panels are highly reflective; however the bottom of this panel may be even more than others; sharply reflecting light and even picking up the colour of well lit material at a reflective angle to the panel.
