This window was easy to install. I decided to flip it and mount it above the half panel. I’m hoping this will keep the chickens out

Nice addition to our greenhouse

Works great for more airflow in the greenhouse

Very flimsy! Quality not as expected.

Installed this as I built my palram hybrid greenhouse. It fits nicely and does the job, but I also purchased the automatic opener which requires removal of the original opener that appears to be riveted on so I am unable to remove. I will play with it some more, but in retrospect I may not want the automatic opener if I intend to add heat in the winter or so I’ve read. Overall, a worthwhile purchase to help regulate the temperature as it does get hot on a full sun day.

This does not fit snap & grow greenhouses and there is no way to adapt it.

Palram products and customer support have always been great. The panel installed as instructed, but louvers were 1/2" short. I called customer support and new louvers are on the way

Not worth the money. Flimsy louvers. Waste of money.

Helps with airflow and to help moderate temperature

Definitely helps ventilation.... Would install during the greenhouse initial construction though directions tell how to deconstruct a finished greenhouse to install. Actual panels seem like the same material as the ceiling panels.
