Work done on Avenida Pau Casals in Barcelona, which was to remove the old blind and severely damaged, and install a new aluminum but this time driven. Aluminum shutters do not age well as composite materials such as PVC or wood, because aluminum is a material with little delay, and this is why they do not suffer the coating applied over it. This type of blinds include polyurethane foam inside, helping thermally and acoustically insulate the outside without increasing its weight. In this paper we installed a total of 18 shades, all synchronized together by stays. At present there are numerous variants we provide automation manufacturers like Somfy from remote controls PBX programming. In the installation of a blind aluminum guides are typically change thereof, for a more efficient, since they include a pile to prevent the passage of air through them. In this paper we use two days of three workers. The extracted material is always taken to Green Point for proper recycling, helping the environment while streamlining our work. For any further information please contact us, we will respond without compromise.
