Work done in the district of Sant Antoni in Barcelona. It consisted of the manufacture and installation of two aluminum windows and a door. Windows were hinged double leaf type, made with the Stilo-50 series in our catalog, which stands out for its good value. They were in white lacquer finish, and possessed a glass 4/12/4 standard camera. We also put thermal aluminum blinds in three pieces. The peculiarity of this work is that a lower fixed glass in windows to save desk to open the windows inside was made. As manufacturers we can develop as structures and happy customer so as to adapt to all existing drawbacks. The old wooden windows were drawn, also we did extract old frames, to earn some light step. The hollow of the old wooden frame was covered with polyurethane foam to improve adhesion and sealing, which was sealed and covered with aluminum sheet of the same color with white neutral silicone. This work was carried out on a morning job of three workers. The fact improve the exterior doors and windows of a home is a good investment in the medium term, since the initial outlay will be repaid in a few years to save on heating and air conditioning, and allow us to improve our quality of life.
