Rabel Envelop 3D is a revolutionary building system invented by Rabel to create uninterrupted fully integrated facades comprised of fixed, sliding, bi-fold, hinged, curtainwall, spider and wall units while keeping a slim structure.
The change from one unit type to the next is seamless and does not require the addition of extra frames. All units follow a slim architecture and are able to make large openings.
Visit us at BAU 2019 / Hall B1, Stand 120 to view the Envelop 3D and other of our systems.
