"Cadireta" curtain wall structure (042)


The stick curtain wall, characterized by the continuity of its mullions, is giving way to a new structural scheme based on solving the area of the slab front -more or less from the level of the paving to the ceiling-, with two lines of transoms joined by pieces of mullions to the edge of this slab.


The objective is to solve, separately to the rest of the facade, the slab front, where all the complexity of the curtain wall is concentrated: fire sectorization; total guarantee of the continuity of the horizontal division between spaces up to the façade; load transmission to the main structure, stake out, among the most important issues to be resolved.
Once this structure has been assembled, the rest of the facade can be closed either with glass panes over two supports or by placing some mullions anchored at any point of the transoms. Both possibilities allow great design freedom to architects.
Due to the clarity of the approach, the fact of delimiting the area of greatest complexity of execution, and the compositional freedom, this system is, today, the one that is being used the most.
