Riverstone Industries Louver Wall Mounted Window Vent

This Louver Wall Mounted Window Vent helps to cool the inside temperatures of any greenhouse or structure. With it's simple but proven design, the louver window, made from extruded aluminum, automatically opens and closes based on the interior temperature of the structure. The vent is easy to install and will require tools to cut the needed opening into the structure wall. When closed the louver slats overlap each other preventing insects and animals from entering.
