L50 allows full glazed panels with a lower thinner profile with 10 or 12mm thick safety glass, which can be fully transparent, frosted, printed or have a film. Mono panels are single opaque 25mm thick panels that can be covered with melamine or wood veneer. Solid panels are made from a 48mm thick sandwich panel which provides a better acoustic behavior, improving privacy, and has the benefit of having half hidden structural profiles. The best part is that they can be mixed with each other.
