The OHL-SD is a slimline drainable louver featuring improved weather performance within a small profile frame. The OHL-SD is designed to prevent water penetration by collecting water in blade gutters, channeling it into downspouts and away from airflow paths.
Ideal for intake applications where wall depth and water ingress are concerns, the OHL-SD combines durable extruded aluminium construction with flexible configuration options. Available in channel or flanged surrounds, with multiple mesh and finish choices, it offers a clean aesthetic, reliable performance, and excellent free area.
Can be made in larger sizes up to 3 metres wide using Holyoake’s proprietary mullion system.
Limited 5-year warranty with every Holyoake louvre!
