Free standing access door suited to non-louvre walls. The standard integrated solid blades (type 30Z) can be punched in three different ways, (P1, P2 or NP), giving the frontage an aesthetic and expressive character.

The DucoDoor Grille scores very highly on burglary resistance. The solid blades make every version vandal-proof. Tested by SKG in accordance with the European standards (EN 1627 and NEN 5096+C2) and a certified burglary resistance class 2version is possible.

The DucoDoor Grille can be made completely draught-proof. The special hinges fitted to the side made it possible to create a large usable width and enabled the door to be opened 180°. Ten-year warranty.


Free standing ventilated louvre door with or without specific requirements for burglary resistance and/ or draught proofing.
