The 12" Aluminum Shutter by Schaefer is a perfect way to improve the ventilation in your greenhouse. The preferred supplier for all of the premium greenhouse manufacturers in North America such as Solexx, Essex, and Sunshine GardenHouse, Schaefer has been making reliable commercial-grade ventilation equipment since 1951.

This shutter can be used together with an exhaust fan to create cross-ventilation. It has an efficient aerodynamic design and mounts flush to the interior wall. When a fan are operational, the weighted louvers draw open by gravity and close as the fan is turned off.

The shutter is made of heavy-duty brushed aluminum for an elegant look as well as added strength and durability. The Schaefer 12" Aluminum Shutter is a perfect addition to any greenhouse and will help keep your plants well-ventilated all year round.
