HH Robertson Fixed Blade Louvres are factory
assembled modular units available in a wide
variety of materials.

Design Features

Fixed Blade Louvres are 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 designers to blend or contrast the louvres with the surrounding materials to achieve the desired architectural effect.
