Combination

Combination louvers blend the aesthetics of a fixed front blade with the functionality of a hidden adjustable rear blade, providing airflow control without compromising exterior sightlines. Available in a variety of frame depths, blade angles, and spacings, all models are constructed from extruded aluminum and feature drainable or non-drainable fixed blades. These louvers are ideal for applications requiring modulation while maintaining a clean architectural appearance. Manual, electric, or pneumatic actuators can be added for automatic operation.
