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 classification up to 3.5m/s face velocity. QEF are not aware of any other louvre achieving an A1 classification. The vertical louvre should be specified where the highest level of weathering combined with exceptionally low pressure drop are required
