Polymer specialist REHAU has developed together with Michael Schmidt the straight-line, delicate track for the tried and tested RAUVOLET metallic-line tambour doors, frame4. The Traget was quite clear: an „Innovation Design“ of a new, subtle track system. With a width of just 4 mm, this frames the tambour door carpet with an elegant metal finish, so a plain surface becomes even more prominent as a visually enhancing element.
