Need more air circulation? Add a Grandio Louver Window to your greenhouse. Louver window frame comes powder coated in green, with 6mm twin wall polycarbonate panels.

Grandio Automatic Louver Window Opener
Automatically opens and closes the louver window when temperature changes. The opener has a metal cylinder containing a mineral which expands when heated. This pushes a piston that opens the vent. As the temperature cools, the mineral shrinks and a spring closes the vent and resets the piston. The opening and closing of the vent is gradual allowing just the right amount of air flow for cooling. This Auto Louver Opener attaches to the Left Side of your Louver Window. Please call to order a Right Side Orientation Auto Opener for Louver Windows purchased prior to September 1, 2016.
