PRIMAT provides the appropriate solution for every shape of fanlight.

Round, oval or angular, the system opens inwards or outwards to suit your requirements. Suitable for one, two and three-section tilt windows, flat arches, and round arches.

PRIMAT opens and closes elements made of timber, uPVC, aluminium or steel which are beyond the reach of the user, with glass weighing up to 40 kg/m², and the maximum sash weight of 80 kg. The opening stay can be operated manually by means of a lever or spindle drive gear or using an electric motor. There are different stay systems available for inward or outward-opening windows.

For an opening width of 190 mm, the compact finely shaped housing is made of light alloy, and the functional parts are made of highly corrosion-protected steel.

Because of strict regard to heat insulation regulations the three-point locking in the opening stay increases the window closing pressure. Because of this it closes very tightly. Mounting and adjustment can be made quickly. The sash closing pressure can be adjusted on the sash block. And in the open position the fixing is storm proof.

A few turns of the crank linkage positions the fanlight as required. Perceptibly convenient is the spindle mechanism with high-grade brass bearing under the cover profile. Alternatively a swivel lever, lockable hand lever, hand lever with transmission or motor drive can be selected.
