Hello, this is ny greenhouse – which as you can see, has gotten beat up pretty good by the Arizona weather. I am resurfacing it with panels that are more durable in the AZ sun.
That said, one roof vent flap is totally broken from wind damage so I taped it closed. The other is not doing well. Both are flimsy as hell. I am going to remove the flaps and am looking for alternative vent options. My two considerations are using galvanized steel exhaust vent caps, 12" opening, 4-6 of them on the roof. Another (suggested by my HVAC friend) is to put a steel whirlybird vent where the flaps are now. 1 each side. I would prefer the former, aesthetically, but I'm not sure about feasibility/functionality of either.
Has anyone used either option? Even better if in the AZ desert?
If I go with the exhaust vent caps, I'm not sure if the rising hot air alone would be enough to get past the built-in damper. Which I suppose I could remove. Would allowing the air to passively flow up into 12" vent caps be sufficient? I also typically have both doors open and an evap cooler in summer. I'd imagine it would work, but who am I.
Worth mentioning, I do not heat my greenhouse so I don't care if the vents are open full-time, so long as rain cant get in and hot air can get out.
Any input is very much appreciated.
