Building located at the Autonomous University of Barcelona in Bellaterra - Barcelona (Spain). The cladding is Blue Slate with 20 mm thickness and measurements of 120 x 60 mm with a structure of continuous joints, both vertical and horizontal. The particularity of this cladding implies the impossibility of machining, as the slate in particular, and to a lesser extent the quartzite, present a laminar molecular composition, therefore, if the edges are machined, it may begin to open through laminates or exfoliation. For this reason, the PF-ALU/CER system was selected in version 14/20 which, supported by the CER Spring, permits stabilization of the panel in its position, maintaining it free from vibrations and from the effects of the horizontal wind load.
