Experiencing blind semi-finished products (101)

In the same way that we wonder whether the chicken or the egg came first, we could ask ourselves who takes the first steps in innovation: the architect proposing new solutions, or the industry developing them?. In most cases, developments in industry respond to new approaches suggested by architects. 
There are several examples of light-weight facades based on semi-finished products, which were used before the companies involved offered the system among their products. These have provided practical experiences from which we have all learned: how to improve the relationship with the floor slab, the window opening, and so on. 

Thank you for running the risk.
