window rebate vents

arimeo window rebate vents are used effectively to prevent mould. Finely dosed fresh air flows in through the closed window via the window rebate vents, so that the structural-physically required minimum air exchange can be achieved without wasting energy.

Window rebate vents react to the wind pressure changes around the building. At stronger wind speeds the air flaps automatically control the incoming air and thus avoid draughts. If the wind speed drops again, the air flaps automatically open for new fresh air supply. arimeo window rebate vents are always installed between the wing and frame of the window, being invisible when the window is shut. They exclusively use the space between the wing and the frame as an air flow path, i.e. the window rebate.


multiple locking system GU-SECURY Automatic

When closing the door, two latchbolts automatically throw a full 20mm and remain blocked until operated.

If required, the automatic latchbolts can be mechanically fixed in the door lock – this is the so called daytime unlocking: the door now can be opened without using a key.

RC 2-tested in combination with different door systems.


comfortable and safe

Shutter systems

more than just darkening

Windows are the connection from the outside world to the inside of your home. They open the room, let in light and air and open the view to the outside. But sometimes they can also compromise the living comfort of a house or building: in hot and cold weather, for example. In sunlight and darkness, in street noise or in prying eyes from outside.

With the wide-ranging high-quality and comfortable shutter systems from various manufacturers, we offer a comprehensive product range which also guarantee a high level of safety and present a valuable contribution to energy savings. All elements such as roller shutter boxes, bars and controler technology complement each other perfectly and thus, add a significantly higher quality of life to your home.
