A louvre system that uses hidden mullions, gives clean, architectural lines because the support system is behind the blades, making the mullions almost invisible. Mullions can be spaced roughly every 1 to 2m and blades are typically 3 to 4m long, (usually dictated by transport restrictions and the weight of the blades). Hidden mullion systems are normally used to provide screening and protection to buildings with multiple openings.
