Aluminium louver systems are developed with the intent of providing a pleasing aesthetic appearance at the same time as providing natural ventilation, controlling light and preventing water ingress. Designed with a choice of frame options, the fabricated louver panels can be glazed directly into the structure or within other metal systems. The louver panels can also be provided with an insulated backing to suit mechanical ventilation systems. Neelkamal Facades can design various other profiles which can be incorporated allowing the architects to achieve flexible designs for the required specification.
