Specialty Louvers withstand severe weather conditions

Airline specialty louvers are designed to withstand severe weather conditions. In order to obtain Miami-Dade County certification, louvers must pass up to four standardized tests in which they are subjected to hurricane wind and rain conditions. These tests are known as Protocol and Application Standards, or PA's. PA-100(A) tests the louver's resistance to wind-driven rain penetration. PA-201 simulates the wind-driven debris that is often present during hurricanes. PA-202 tests the louver's ability to withstand high levels of static air pressure. Finally, PA-203 is a cyclic wind pressure test, which simulates the forces applied to a louver by repeated wind gusts. Airline's LSA6D45-DC louver meets standards PA-201, 202, and 203. The LSA5CDD and LSA8CDD models are specialty louvers designed to eliminate water penetration in wind-driven rain conditions.
