In the closed position of the ventilation window the insect netting has a folded condition and in the open position of the ventilation window the insect netting has an unfolded condition. The greenhouse also comprises a guide which is mounted to the ventilation window and extends along the insect netting in the unfolded condition thereof, and at least a guide element which is mounted to the insect netting through a connecting member and movable along the guide. At least one of the roof and the ventilation window comprises a sealing portion for sealing the ventilation window and the roof with respect to each other in the closed position of the ventilation window. In the closed position of the ventilation window the sealing portion contacts the connecting member and is located between the guide element and the insect netting.
