AVS50DR Drainable Louvre
The AVS50DR is a drainable aluminium louvre system developed for applications where both airflow and rain defence are important. The drainable blade design helps manage water penetration, making the system suitable for more exposed external environments.
At Finish Architectural, the AVS50DR can be manufactured to bespoke dimensions and finished to suit individual project requirements. Ideal for ventilation zones, plant screening and external service areas, the system combines performance, durability and flexibility.
