The wall-rail is mounted around the perimeter of the room, on either flat or curved surfaces. There is no need for interior tracks or supports.
Rails are available in a variety of styles, and can be either visible or fully concealed.
The custom-cut film is made to measure in the factory, and when it is brought on site it is heated before being unwrapped. Then the lightweight ceiling is unwrapped and stretched into place, starting with the corners. Its semi-rigid harpoon edge is fitted into the wall rail, securing the film without intermediate supports. Penetrations are all cut in the field to assure a proper fit. The number of corners and penetrations required determines the complexity, and the complexity determines the actual amount of time required.
