The stick curtain walling system consists of a bespoke aluminium grid of vertical elements (mullions) and horizontal elements (transoms). These mullion profiles are fixed back to the building structure (beam or slab) and then glass, spandrel or ventilated cladding elements are inserted in the grid on site. Mullions and transoms are manufactured from extruded aluminium bespoke profiles, cut and fabricated in the factory, while the grid is assembled and fixed to the structure on site.
