Louvre windows allow the cooler air during the summer months to enter the greenhouse at the lowest possible point. This in turn pushes the warmer air out of the open roof vent.

This movement of the air is essential in the warmer months as stagnant air can quickly cause fungal rot and other plant diseases where the humidity is high.

Opening the greenhouse door is not as effective, as it allows a wall of air in rather than a stream, so the circulation is not as effective. Leaving the door open also means that your greenhouse and its contents are at risk from the neighbours' domestic pets, urban foxes and other pests.

How to Fit a Louvre Window

As suggested a louvre window should be fitted near the base of the greenhouse rather than higher up. It will fit between the upright glazing bars and will replace a pane of glass. Detailed fitting instructions are supplied.

With horticultural glass you would simply replace a panel of glass with the louvre panel. With long pane toughened glass you would normally be supplied with one additional panel cut short to accommodate a louvre if required. Fitting a second louvre may involve buying an additional panel of glass. With poycarbonate you would normally cut a panel size yourself. This particular louvre is fitted with toughened glass in the blades.

Halls 24" X 18" Louvre Window - Satisfactory product - but delivered to wrong address.

To begin with my louvre window was delivered to the wrong address which was a business premises. However, they know me and brought it round to me rather than send it back. It was well packed. Anyway, we finally managed to fit the louvre window to replace a broken pane of glass in my Halls Magnum greenhouse, but it was a tight fit. However, the frame went in easy enough once I'd made enough room for it, but it did take 2 of us. Getting the glass panels in was a fiddle and one thing I would like to see is firmer fixings for the glass. I would have expected better for the money. The panels have stayed in place after a week of hot weather but not sure how they will fair in bad weather.
