Louvre Kits & Automatic Openers
Louvre windows are particularly easy to install into existing greenhouses and can be fitted with an automatic opener for reliable operation. Ideally use louvre windows as low level ventilation by adding louvers low down in the sides of your greenhouse or in the back of the greenhouse. A louvre window placed in the back wall of the greenhouse, opposite the door, will help to draw air through the greenhouse, from one end to the other. Alternatively position the louvre windows to suit the main crops which you grow - for example, if you grow tomatoes every year than fit louvers where they will be grown, so that fresh air can be drawn around the dense foliage.
