10 tonnes of aluminium box section extruded with port holes.
5mm aluminium 5083 for the top and bottom of the louvres , laser cut holes into the 5mm Aluminium to allowed us to fix through the top and bottom and into the box section so no fixings would be seen. We then powder coated these and added a sound proof acoustic board to the back.
