This concept of façade cladding, with a flat appearance and hidden fixings, is designed for both new buildings and renovations. Its particular geometry (available in 4 versions: JI Ponant W, JI Ponant M, JI Ponant Convex, JI Ponant Concave) allows the creation and to play with light and shadow on the facades. Its interlocking system allows products of diff erent shapes to be “mixed” on the same façade. The sidings are mechanically fi xed to a secondary framework attached to the structure. This product requires an adjusted support or an adjustable framework. It is not possible to use it as ceiling application.
