One handle, multiple openings

Multisky from Maco allows users to achieve ventilation via a top level tilting sash.

“Gone are the days when you would need to go and find a rod to open a fanlight window, use a complex and unsightly drive rod system or stretch and strain to reach the opening handle,” the company said in a statement.

Full operation is controlled by keyed locking points, meaning security and full opening is still limited by the key holder, but the key holder is not required to achieve ventilation.

The one handle on the lower window allows the top sash to be tilted using Maco’s tilt and turn hardware. However, in contrast to conventional fanlights, the fanlight sash can still also be fully opened.

Not only does it maximise air exchange for ventilation when tilted by allowing the warm air under the ceiling to escape, the Multisky system also allows easy cleaning of the outside glass when the windows are fully open.

The multipoint locking system closes and seals all points. This enables better security as well as weather performance, air permeability and acoustic resistance.

The system can be applied to timber as well as PVC profiles. No widening of the frame is needed either as no space is required for the surface-mounted operating elements, making fabrication simpler too.

The Multi Sky system works particularly well in buildings such as schools and hospitals for example who could utilised the safe and secure ventilation of the top fanlight window. This would allow the ability to be able to offer easy and safe ventilation for all users from the easy to reach window handle. The lower sash remains locked and the top sash tilted unless both are opened by the key holder, only accessible via a lock.

Maco will also be exhibiting at Fensterbau on March 21-24, 2018.
