 Renovation of the totality of the facade in the year 1996.
Special ‘guillotine’ windows with counter-weights placed at the sides, inside hollow doorjambs. The most notorious characteristic of these windows consisted in that three vertical panes could be activated and/or work at the same time.
The constructive system of the windows was extremely complicated. The rehabilitation of the original windows was absolutely impossible because the profiles and the crystals of thermal protection could not be incorporated, due to the fact that the wooden profiles rotten and inflated, in a way that most windows could not be activated. State of the work Guillotine windows of the 30’s, as it has already been indicated, in terrible conditions. Diagnosis Since there are no more existing fabrication diagrams for the typology of these windows, and the suppliers cannot be any longer found, (as an example, those ironworks cease to exist,) the windows had to be practically re-invented.  Solution All the windows of the building were dismantled piece by piece, with special meticulousness in the mechanisms of the ironworks, bearings, weights and other systems to activate the windows. Subsequently all the pieces were codified. Furthermore, a problem with the balancing had to be solved with weights, counter-weights, and pulleys, in order to compensate for the glassware’s weight.
The dimensions of the profiles were by all means unable to be changed which led to an exploration of the market in order to find valid elements for this peculiar constructive system.
Jointly with the architects of the project, specialized engineers and our technical department, we created a general planning in order to study the executing plan so as to reach the designated objectives.
After this theoretic and studious phase, we proceeded in gathering all the pieces, fabricating a prototype, that later was put under our “test bank” in order to guarantee stability, security, and functionality, as well as its preservation. After a few improvements on the prototype, we were able to green light the production of windows.
The preparation time became that of six months. After that we continuously fabricated 240 windows for this specific project and up until this day, almost 12 years after that, there has not been any problem.
