With a surface measuring 1500x1500mm, Iridium XXL is the new industry standard for project designers and for projects where dimensions make a difference. Thanks to its native 6 mm thickness, Iridium XXL provides lightness and strength in all applications - even the ones you’d never even imagined. Iridium XXL is the result of on-going research, development and innovation, which Grestec maintains to come up with possible design applications that are always fresh and new. The big panels in our Iridium XXL meet architects’ need to speak a language that interprets the aim of the contemporary space.
