Acoustic Blinds
Acoustic Louver is designed for use at the ends of air ducts, generator rooms, engine rooms and similar places where acoustic isolation is required. This louver is ideal for reducing sound transmission to the environment and minimizing outside sounds. Available in three different models - AL-150, AL-300 and AL-600 - it adapts to different performance requirements. The wing structure provides rain protection and powder coating offers high corrosion resistance. Furthermore, the bird wire prevents foreign objects from entering the air duct, which makes the roller shutter both functional and durable.
