Perforated Bruag facade panels can be used as sliding shutters, providing a special ambience both day and night. The exquisite perforations give rise to a whole variety of lighting patterns, depending on the time of day and the angle of sunlight. During the day, beams of sunlight seek a path through the imaginative pattern of perforations, giving rise to an interesting array of shapes in the interior. During darkness, fascinating lights and shadows penetrate to the outside.
