Single Bank Weather Louvres
QEF offer a range of curved blade and flat blade single bank louvres.
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.
The aerodynamic curved profile and reduced pitch present an aesthetically pleasing louvre for architectural facades. The smaller louvre depth is of benefit where space is limited.
50 Flat S
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.
50 HP Profile
The QEF 50 HP Profile Blade Louvre is specifically designed to use with the QEF 50HP Louvre, being a mimic to the front portion of the QEF 50Hp Blade, where a portion of a louvre wall is purely decorative but needs to match the active 50 HP louvre.
Single bank extruded aluminium curved blade louvre pitched at 75mm, the standard commercial louvre blade pitch with an aerodynamic curved profile for smooth airflow. Used for general applications where good airflow is required and reasonable weathering is achieved except under severe conditions.
QEF 75 Flat
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.
QEF 75/35 Flat
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.
