Greenhouse Windows

The main function of a greenhouse roof vent or window is to allow the very hot air that rises into the roof space in your greenhouse to escape. So it is important that you have sufficient roof windows in your greenhouse for its size. However, it is a combination of roof windows and louvre windows that will improve air circulation in your greenhouse.
