Wind-driven rain louvers
May 21, 2018
Wind-driven rain louvers provide the maximum amount of protection in keeping wind-driven rain from egressing past an opening. Wind-driven rain louver models have both horizontal and vertical orientations and utilize a chevron style rain resistant blade that rejects horizontal rain as it comes in contact with the louver. These louvers are tested per AMCA 500-L at wind velocities of 29 and 50 miles per hour. Based on the results of the testing, the louvers are then graded from A to D, with A being the best performance at 99% effective or better at repelling wind-driven rain, B being 98.9% to 95% effective, C being 94.9% to 80% effective, and D being below 80% effective. Additionally, some wind-driven rain models have also been tested for impact and qualify as louvers that can be installed in states like Florida where hurricane conditions exist.
