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 cycling of the air is essential in the warmer months as stagnant air can quickly cause fungal rot 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 neighbour's domestic pets, urban foxes and other garden animals.

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 piece of polycarbonate OR you may have to cut the existing polycarbonate. Detailed fitting instructions are supplied.

The louvre in the photo is fitted with toughened glass in the blades, and not polycarbonate. For illustration purposes only.
