Can roll-up grilles be used on both sides?

Many models of roll-up grilles, like the elegant "Optiline" roll-up grilles, can be used on both sides by turning them over, thereby significantly lengthening the service life of the grilles.

Can roll-up grilles be shortened?

Yes, roll-up grilles can be shortened and also lengthened.

Can roll-up grilles be adapted to the dimensions of the building?

There are almost unlimited possibilities in this respect:

  • Recesses, especially to accommodate columns or posts
  • Curves
  • Mitres cut to different angles
  • Polygonal joints to the facade of the building
