Aluminum Shutter


Provides fresh air

Greenhouse shutters allow air to be drawn into the greenhouse by the exhaust fan.


The Heavy-Duty Aluminum Shutter requires a Shutter Motor to open vanes automatically when the exhaust fan turns on, close when the fan is off.  (Order C3259 Shutter Motor separately.) For non-electric solar control, see C3534 Liberty Kit.

The passive Mill Finish "Economy" Shutter does not require an electric motor, as it is very lightweight galvanized aluminum to open by fan draft. 

Both shutter styles offer louvers with felt edges. The Heavy-Duty Aluminum shutters have white painted louvers.
