Metal

Have a look to this façade solution, to the characteristics of the different layers overlapped, and then have a look to the Torre Agbar façade solution.

They look quite similar: a wall, in one case made of small elements while in the other made of concrete poured on site, a ribbed metal sheet, glass slats. In both cases the thermal insulation is in the inside.

Unitized panels: moving from the high-technological glass façade systems to a common façade solution with any openings distribution and finishing material possibilities.

This case helps us once more to illustrate how difficult it is naming and classifying the wide range of contemporary façade solutions.

It is not easy to constructively solve the façade of a building when this facade is supposed to be placed between the edges of the slabs, and the slabs have all of them different perimeters. The distance between a point on the edge of a slab and the equivalent point on the upper slab is always different.

Here we refer to a solution of the kind in the study "Profiled metal sheets for the free design of continuous enclosures". These enclosures reach from the façade to the roof and resort to the same construction system, with on-site profiled metal sheets as the main ally.

Sober and spectacular coherence in this example where the structural system is the only one articulating the whole.

This case helps us to illustrate these facade solutions based on the summation of "windows". See the study Façade of windows.

Sober architecture but a confusing solution.

Which is the main façade layer in this concrete façade? The 8 cm think concrete panel or the brick wall? 

The relationship between the façade enclosure and the structure is a recurring theme in Batlle and Roig’s work.

In the CMT headquarters the structure is located offset from the façade to allow free development of a nearly entirely glazed envelope.

This is a unitized façade system, which means a completely prefabricated curtain wall solution. A panel is used with all the onsite mounting benefits that panels can have. What is more it is light, so big components can be used that are perhaps two stories high. During preassembly, all the façade layers can be incorporated into the same frame, and thus into a single panel. The glass does not need to be related to transparency; it can simply cover the blind area of the façade to provide a continuous image from the outside, as we normally do with the slab edge front.

In this evolution of the rain screen façade towards prefabrication, seeking to build both, the interior and the exterior layers, with dry systems highly prefabricated, it is not that usual to find massive solutions. Those solutions would permit, not to lose thermal inertia, or decrease the acoustic barrier.

The inner sheet based on heavy concrete panels is a very good option.
