Our high-performance louvers have gone undercover.

With Construction Specialties Perform Louvers, you get the air movement, security and sight-screening performance of our standard louvers, under the cover of a modern perforated aluminum skin. The first and only manufacturer to offer a fully concealed louver system that's been tested to stringent louver air performance and water penetration criteria in the industry, CS turns louvers into a covert operation that's proven to perform.

Camouflaged Air Flow. 

At 855 Avenue of the Americas in Manhattan, design architect Cook + Fox used CS PL-5700 Storm-Resistant Perform Louvers to provide an airflow solution that also complements the building's unpretentious glass design through subtle bands at its top and bottom. So when the spirit of design is clean and unembellished, CS prefers to go incognito.
