The OVL-120 louver is designed from proven Holyoake louver technology and engineered for data centres and high-volume mechanical systems. It combines Class A rain penetration performance with Class 1 aerodynamic discharge and proven compliance through BS EN 13030:2001 testing.
The Holyoake OVL-120 system offers a striking vertical façade louver alternative that can be used in place of more conventional horizontal configurations while providing an effective and functional louver system. The blade features a unique profile that captures water on its surface and minimises carryover through overlapping blades – ensuring both aesthetic appeal and high-performance functionality.
