PRIMAT opens and closes elements made of wood, PVC , aluminium or steel which are beyond the reach of the user with glass weighing up to 40 kg/m².
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.
Fresh air all round!
Staircases and entrance halls tend not to be ventilated very much.
However, you should be aware that coats and floor washing result in a build-up of moisture which can result in mould formation. Permanent ventilation is not a problem in such spaces as they are usually not heated much. The optimum opening system here is a turn and tilt or fanlight window. The latter can conveniently be operated by a lever when within manual reach.
The use of spindle drives or, alternatively, electric drives is recommended for maximum convenience and to allow infinitely variable adjustment of the opening width.
The HAUTAU PRIMAT range has answers to almost all problems!
