“Sandwich” type panel with PVC skins and extruded polystyrene core, very light but at the same time quite rigid.
It is supplied with transparent double-sided in polyester 23 μm adhesive sheet mounted, Ph neutral, suitable for fine art, water-based, “environmentally friendly”.
We usually don’t lay any side cover on the side of the panel; this kind of panel is perfect for holding the paper in a thick wood frame.
