Lexan Panel: If your greenhouse is made of glass, we cannot cut the glass to insert the exhaust fan in the gable end. We recommend purchasing a Lexan panel that we customize for you, we cut to make sure the exhaust fan fits in the gable end perfectly.
* Disclaimers: Adaptations might be needed when this fan is installed in ANY greenhouse. This fan can be installed in a polycarbonate greenhouse by cutting through the polycarbonate sheet to make sure the fan fits properly. If you decide to put it in a glass greenhouse, you won't be able to cut the glass because it will shatter. We recommend using a lexan panel to fill the gaps. ****if you purchased or own a Exaco Victorian greenhouse, you can purchase the lexan panel from us and we can cut it for you to fit the gable end of the greenhouse to make sure the fan sits there properly, just let us know*******
