Screen device which is intended to be arranged around an opening of a building, such as an agricultural or horticultural greenhouse, which opening can be closed off by means of a closure panel 4 which can move pivotably between an open position and a closed position, which opening 2 in the open position of the closure panel 4, is at least partially shielded by a screen 11 made from air- permeable material which, in the opening 2, extends between the building 1 and the closure panel 4, the screen device comprising one or more frames 8, 8', 8" which are U-shaped when viewed from above and are connected, along their periphery, to the screen 11, the frames being dimensioned in such a manner that they are located substantially concentrically inside one another and can be moved along one another in the direction of movement of the closure panel 4. <IMAGE>
