Aluminium Louver 75-E

75E detail fixation

A 75-E louver system is a non-retractable slatted blind with 75-E louvers. These louvers are made from high-grade extruded aluminium, and have a width 75 mm. A 75-E louver system is suited for all kinds of internal and external installations; horizontal, vertical, sloping, and upside down. 75-E louvers are usually movable, but can also be placed in a fixed position.

Profile of the 75-E louver

The front, the visible side, of the 75-E louver has a convex, rounded, shape. The back of the blade is designed for optimal fixation of the clip that holds the slat. The design of the back side of a louver follows from the function and form of the front.
