DucoGrille Classic G 70V

DucoGrille Classic G 70V

DucoGrille Classic G 70V is a recessed wall louvre manufactured from extruded aluminium sections. Insect mesh is fitted as standard. The unique “V”-shaped blade ensures better water resistance and makes the louvre grille ‘penetration-proof’ and difficult to see through from the outside.

Also available in a variant with vertical louvres: DucoGrille Classic 70V Vertical.
