This system allows the construction of facades using the seamless integration of various modules. A single track without intermediate posts can hold construction elements such as sliding, folding, pivot, pivot-slide doors, casement or fixed windows, curtain walls, glass railings, drywall partitions as well as spider-glass constructions, shading louvres or insect screens. All the modules can lock into each other in a row, or above or below each other to produce a continuous facade. Furthermore, the modules nest into one another without the need for extra frames to create a high level of sound and heat insulation.
