Concrete wall

Batlle and Roig designed a double skin façade for this office building in 22@. The interior layer meets the thermal requirements as well as air and water tightness, while the exterior one delimits the building volumetrically and seeks to improve its thermal behavior.

It is difficult to understand the need of building this thick, load bearing, cast in-situ concrete wall hidden behind a light cladding made of different layers: mineral wool; coloured ribbed plates; glass slats. In the inside, the concrete wall is again hidden, in this occasion by furniture. The climbing formwork system that made possible this wall had to be successively cut so as to be adapted to the changes on the diameter and curvature of the tower. Not less must have been the difficulty when preparing the reinforcement.
