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.
