There are predominantly 2 types of external louvre systems available in the Architectural Aluminium market.

• The lazy Z clip-on type of louvre slats are available in roll-formed and Aluminium extrusions. The sizes range from 70mm up to 130mm.

• Elliptical louvre blades are available as Aluminium extrusions ranging in sizes from 50mm right up to 450mm.

External louvres offer energy savings and protection by creating shade and avoiding the need to reduce the temperatures of overheated rooms and buildings. Reducing the amount of energy required for lighting, by optimizing the transmission of free natural daylight. Enhancing indoor comfort and helping to stimulate productivity.

Louvres are slats or blades that are usually arranged horizontally in a window. The slats are positioned at an angle to allow in air and light but keep out direct sunlight and rain.

Extruded Aluminium louvre slats or blades are available in a range of popular external-grade powder-coated Aluminium finishes. The lighter more reflective colours tend to be the most popular colour choice.

The slat or blade orientation is dependent on building elevation and design aesthetics. Elliptical blades tend to be the preferred type for vertical applications due to the longer span between support structures. Louver slats or blades can also be installed as projecting sunshades generally installed at the head of the glazing (i.e. brise-soleil systems).
