Those vents and vent openers are heavier duty than what I have. The roof opening ones generally are but I wanted to avoid roof openings given how fierce the wind can be at times. I had visions of the wind catching an open louver and either damaging it or the greenhouse., and so I stuck with side wall louvers instead. Note that my structure is something I designed and had built. It is 16 X 16 with the southern half being the greenhouse and the northern half being the potting/storage shed. There is a door in the middle between the two spaces. The potting/storage shed part has 4 windows and an exterior door. It is 12″ tall in the center, 8″ on the outside. This is what I have:

And with the automatic openers that seem to be OK but that I removed on account the louvers are flimsy.
