With Construction Specialties Perform Louvres, you get the air movement, security and sight screening performance of our standard louvres, under the cover of a modern perforated aluminium skin. The first and only manufacturer to offer fully concealed louvre system that’s been tested in accordance with BSRIA standards for air performance and water penetration, Construction Specialties turns louvres into a covert operation that’s proven to perform.
Why Perform Louvres

Unlike decorative mesh, which can harm mechanical quipment, Perform’s perforated skin is engineered to work in harmony with the interior louvre blades to provide unparalleled air intake and water protection performance. We even offer a Storm Resistant model (PL-5700).

Perform Louvres are available to integrate into any curtain wall system. Whether capture, butt-glazed or even a custom directional reveal, Construction Specialties can provide the solution. Perform Louvres mold to your design’s character, whether as a dramatic accent or subtle nuance.
