Hollow louvres are often preferred for their lightweight construction, which makes them easier to install and reduces the overall weight of the building. They also offer a range of benefits, including improved ventilation, light control, and privacy. By adjusting the angle of the louvres, the amount of light and airflow can be controlled, and privacy can be maintained while still allowing natural light to filter through.

Aluminium hollow louvres are also resistant to weather and corrosion, making them ideal for outdoor use. They can be coated in a range of colors and finishes to complement the overall design of the building. They are commonly used in commercial and residential building design, as well as in industrial applications such as ventilation systems for factories and warehouses.
