Design features

Designed for either single louvre use in small openings or multiple louvre applications in larger openings where the vertical mullions are to be features. Louvres can be stacked in banks with the proper supporting steelwork to provide a large louvre opening area. The louvres are ruggedly and accurately made, and the wide variety of available materials and finishes enables the designer to blend or contrast the louvres with the surrounding materials to achieve the desired architectural effect.
