Fll 131 is available with manual, electric or pneumatic actuators.
As well as the examples illustrated here, there are a range of applications and fixing arrangements that can be provided.

It always depends upon the idea. If you’re looking for a glass-free louvre vent, then we can supply one. It’s not only possible, but can be advantageous: for example for internal applications such as smoke shafts.

Louvre blade design:

Louvres are frameless, manufactured from thermally broken extruded aluminium. The blades are centre-pivoted and close flush with the external vent frame.

Frame design:

Thermally broken aluminium extrusions. Frame sections are butted together and screw-fixed.

Glazing:

Frameless thermally broken composite aluminium. Supplied with a fixed height of 131 mm.
