Construction Specialties’ A6390 Acoustic Louver offers 33% free area, enabling it to provide high airflow capability without compromising sound control or protection from water penetration. The louver can be built into a facade or used as a freestanding vision barrier screen on rooftops or equipment pads—an application ideal for data centers.

The A6390 features a 6-inch depth with 4-inch blade spacing and is AMCA certified for water penetration, sound, and performance. Sound attenuation has been rated at STC-10 for the louver application and STC-9 as a screen.
