This Louvre Window Kit consists of the operating components for a six-bladed louvre, complete with all the fixings required for fitting to an aluminium greenhouse. A Louvre Window placed low in the sides or end of any greenhouse will help improve airflow and aid summer ventilation; both desirable traits when growing in a greenhouse.
Increased airflow will help keep humidity levels down and avoid the conditions that certain fungal diseases - such as botrytis - enjoy, and the adjustable cooling effect of the louvre window in the summer will be welcomed by plants and gardeners alike. Glass blades for the Louvre Window Kit are not supplied, but the pane you will have to remove to fit the unit can be cut to minimise waste. Glass panes are also available from glass merchants or glaziers who will usually cut the glass into slats to fit the kit. The Louvre Window Kit replaces a 61cm (24") square pane.

Purchased two louvre windows for my 8x6 greenhouse on allotment. Had a little issue trying to screw the four pieces together. Would have been easier if they had some slot or clip to hold each piece together prior to adding screw. I opted to use twin wall polycarb sheeting I had lying around instead of spare glass. It took me 15min to cut polycarb sheet to size with a Stanley knife and the pieces fit perfect. No sealant needed or bending metal ends. Louvres do stick a bit when opening and closing but with regular use over the spring/summer should loosen up. Louvres are placed low with one on south facing side and other in west facing gable end. They have created a 2cm gap between louvre(s) and the bottom frame but I filled each gap with a piece of leftover polycarb sheet. Gap seems to be created because louvre is installed from inside greenhouse and rests on inside frame unlike glass panes which are clipped into place on outside. Delivery of first louvre was within 48hrs of ordering, second took four days to arrive.
Bought 2 of these for my 2 greenhouses. The first one I fitted I cut the glass using the pane I had removed. Not had much experience before doing that kind of thing but they were o.k. Didn't think they were going to stay put in the frame though so applied some silicon sealant to hold. I didn't think about bending the metal as I thought I might damage the glass. In the other one I had a sheet of 610x610 4mm polycarbonate and cut that up using my jig-saw. Much better fit than the glass and no need for any silicon or metal bending. In both cases, I found the same as the other reviewer in that I had a gap between the top of the louvre and the pane above. Have a couple of broken panes left after storm damage so am going to cut them to an appropriate size. Then I'll cut a bit of the upper pane and make one larger pane that will fit using the "Z" Clips to support.
This product does the job of a creating a good air-flow through the greenhouse which will benefit crops like tomatoes by aiding the removal of hot stagnant air in summer. Bought with the automatic louvre opener it was fiddly to fit and the instructions for both items could have been better. How easy it is to fit depends on the construction of you greenhouse. I had to buy a piece of angle aluminium to support the panes of glass above the louvre. One of these also had to be replaced with a pane of non-standard size glass.
