QEF

Single Bank Weather Louvres

QEF single bank weather louvres are engineered to provide effective, permanent ventilation while offering good protection against wind-driven rain and debris. This solution is ideal for general applications requiring a balance of significant airflow and weather resistance.

Single Bank Weather Louvres Range

Single bank extruded aluminium louvre pitched at 33mm. A bespoke design to achieve the architectural design intent. The system achieved Class C4 up to 1.5m/s face velocity. Suitable for applications where a small format louvre is desirable and intake velocities are low. Available with flange, glazing or slim casing options.

QEF 50 Curved Blade single bank extruded aluminium louvre pitched at 50mm. This is a scaled-down version of the 75 Curved Blade, resulting in an improvement in the weathering performance due to smaller blade gap and limited reduction in the airflow.

Single bank extruded aluminium louvre pitched at 75mm with a 35mm front face. A bespoke design to achieve the architectural design intent. The system achieved Class A4 up to 0.5m/s and Class B4 up to 1.0m/s face velocity. Suitable for applications where the blade shape is desirable and intake velocities are low.  

Single bank extruded aluminium flat blade louvre pitched at 75mm, the standard commercial louvre blade pitch to be used where sharp lines and flat surfaces form part of the architectural design. Used for general applications where good airflow is required and reasonable weathering is achieved except under severe conditions.

The QEF 50 Flat S Blade Louvre is an improvement on the standard 50 Flat Blade, the ‘S’ referring to the Stiffening of the front edge with a return.
