ABSTRACT:
The upper horizontal main frame member (1) of a roof window is designed as a hollow box-like structure comprising an inner ventilating compartment (12) which through a flow passage (18) provided with an adjustable damper (19) communicates with an outer ventilating compartment (13) with air exhausts (20, 21) positioned at both end walls (22, 23) of the box-like structure in the outer side of the roof.
An aeration is thereby obtained which is also effective when the window is provided with a rolling louver assembly (15).
An exhaust fan (26) may be accommodated in the inner ventilating compartment (12) and the structure may be provided with separate remote-controlled motors for the exhaust fan (26), the rolling louver assembly (15) and the damper (19).
In a large room installation with a number of windows more windows may, for instance by grouping, be operated from a single control unit.
