Keep your greenhouse well ventilated whilst your away from home.
By adding an automatic louvre vent opener to your greenhouse louvre you will never forget to keep your greenhouse ventilated as it does all of the hard work for you by opening and closing with the changing temperature.
The Auto Louvre Vent Opener is simple and easy to install. The cylinder contains wax, that when heated pushes a piston that opens the vent, as the wax cools when the temperature drops, the piston will retract and close the vent.
Each Auto opener comes with a release catch that allows you to use your louvre manually should you need to.
Our Auto Louvre Opener will fit most popular louvre models.
