Work done in the Sant Martí district of Barcelona Provençals. It consisted of the manufacture and installation of three double-paned windows and two doors with fixed side glass, made from the material of the Stilo-60 series with thermal break and the lacquer finish RAL 7022. In this case the client wanted to insulate your home from the noise as it was situated opposite the Gran Via de les Corts Catalanes in Barcelona, where vehicle traffic is constant and annoying. We use glass 3+3 butylado acústico/12/4 Guardian Sun, acoustic glass to reduce we get about 50 decibels of noise nuisance, and further thermal treatment thanks to Guardian Sun, which is four times more efficient than glass single or monolithic. And thanks to the thermal break ( RPT ) in the grid, we get even more thermal efficiency, as we drive aluminum outdoor temperature inside the housing, since the polyamide incorporating prevents it. The largest glasses had to upload the facade by lift, since the largest glass weighed 100 kgs, and the staircase had bad turn. Glass is a crucial element in an enclosure, since it is occupied by the largest area of the same, to hold glasses good good profiles as the Stilo-60, which thanks to its 60 mm sheet thickness can incorporate glasses are necessary wide and heavy. During the installation of polyurethane foam injected in the contour of the new frames, which was lined with aluminum sheet of the same finish as the window, and then sealed with silicone neutral black color. This work takes a full day of four workers, and did not involve any extra difficulty that could not be anticipated beforehand.
