Double bank extruded aluminium curved blade louvre pitched at 50mm. Vertical aligned the QEF Vertical 50 Chevron louvre achieves Class A3 up to 3.5 m/s face velocity, with insect mesh fitted.
QEF
Vertical Louvres
QEF Vertical louvres are an advanced architectural solution engineered to provide exceptional rain defence and airflow management, particularly effective in challenging conditions like wind-driven rain. With blades oriented vertically, they use gravity to channel water away from the building, safeguarding internal equipment and improving the building’s energy efficiency.
Vertical Louvres Range
Vertical high performance louvre based on typical moisture eliminator blade design. Vertical aligned double pass curved blades with large integral water trap.
QEF Vertical 33 louvre achieves Class A2 up to 3.5 m/s face velocity, with insect mesh fitted.
Multi-pass extruded aluminium curved blade louvre pitched at 37mm, with louvre blades set in the vertical. The ingenious design of this louvre is the result of extensive research to produce a louvre capable of withstanding heavy rainfall whilst acting as an intake louvre.
The results achieved at BSRIA exceeded all previous records with an A1 cla...
