Work done on the La Sagrera of Barcelona. Was to dismantle an old enclosure type iron outdoor gallery, which was in very poor condition, and install a new aluminum. Once taken measures gallery in question, proceeded to manufacture in our workshop in Barcelona, we elaborating it in aluminum spool type Series A-70, with white lacquer finish and single or monolithic Carglass New Glass. During Installation, we find the difficulty of extracting the old iron frames, strongly embedded in the work. In this case the client asked for a job as tight as possible price, and hence simple windows were installed, much less expensive than the rest. As far as possible is advisable to install glass type camera or Guardian Sun, up to four to increase their efficiency, and a return on investment within a few years, considering that the most important element in a window is glass, since which is the greater overall area occupied. The outer joints were sealed with polyurethane foam which was lined with aluminum sheet and then sealed with neutral silicone. Inside the enclosure, the joints was sealed with white paintable caulk. This job lasted about 4 hours of two workers.
