External Louvres

Type R400

The R-400 mobile slat system provides adjustable sunlight protection for roofs and facades, reflecting and/or absorbing sunlight before it reaches the building’s surface so that this heat is absorbed or reflected and dissipated to the air, with the consequent energy saving this provides in hot weather. It can be installed horizontally or vertically and oriented from 0º (closed position ) to 150º (maximum recommended open position), depending on its drive, to make maximum use of the sun’s light and heat in cold weather. Option to install photovoltaic panels on the outside of the slat to generate power and achieve energy self-sufficiency.
