 Formed Stationary
Louvers
Applications
In addition to our extruded aluminum models, Airline offers an
extensive line of fabricated louvers. These models give the designer great flexibility.
A number of different blade types are available including straight,
baffle and sightproof (chevron). The numerous possible combinations of material and blade
style allow the designer to select a louver for almost any application encountered.
Most often constructed of 16 gauge galvanized steel, they are also
available in stainless steel, copper, aluminum and other materials to suite different
applications and environments.
Airline has the capability to manufacture copper dormers for use
with louvers to achieve the desired architectural appearance.
