Double Bank Louvers
What is Double Bank Louvers?
Double bank louvres feature two rows of blades, typically arranged at different angles to enhance their ability to resist water penetration while still allowing substantial airflow. These louvres strike a balance between ventilation and weather protection.
Key Features:
- Improved Weather Protection: With two rows of blades, these louvres are more effective at preventing water ingress and blocking debris, making them suitable for more challenging environments.
- Good Airflow Performance: Double bank louvres still provide significant airflow while improving resistance to rain and weather compared to single bank designs.
- Aesthetic Flexibility: These louvres can be designed to complement the aesthetic appeal of modern architectural projects, offering both form and function.
