Test Method for High Velocity Wind-Driven
Rain Resistant Louvers

Did you know that, if located in the Hurricane-Prone Region, all intake and exhaust louvers must comply with AMCA 550 (Test Method for High Velocity Wind Driven Rain Resistant Louvers) per the International Mechanical Code versions 2012 and 2015? The AMCA 550 test standard simulates external wind speeds up to 110 MPH with an external rainfall rate of 8.8 in. per hour. To pass AMCA 550, no more than 1% of the total sprayed water volume may penetrate the louver. If your state has adopted International Building Code 2012 or 2015, now is the time to ensure that all intake and exhaust louver specifications call for an AMCA 550 Listed louver, if located in the Hurricane-Prone Region.

Airolite offers a complete line of AMCA 550 listed louvers, ranging from high performance vertical blade products, dual-module horizontal front/vertical rear louvers and combination louver-dampers that will not only meet the function required, but the form desired.
