Automatic Louver Vent Arm Opener, for Palram and Rion Side Louver Greenhouse Windows 

The Automatic Louver Vent Opener was designed to automatically control the temperature and provide additional ventilation for all Palram Greenhouses. As the air inside the greenhouse warms, the vent gradually opens to allow the correct amount of airflow into the greenhouse and closes when the optimal temperature is reached. Its mechanism operates with a metal cylinder containing wax that expands with heat to push a piston, which opens the shutters, as the air gets warmer then contracts as it cools, closing with the use of a spring. The Automatic Vent Opener operates without the use of electricity.

The Automatic Louver Vent Arm Opener is evocative, to say the least, but that's why you're drawn to it in the first place.
