Thanks for the photo. What do you leave open for ventilation in the winter?

Sorry, I should have included that in my original post. Temperature typically ranges from low teens to high 80’s. We do get snow, but not all winter long. We built the roof overhangs 18”-24” to help prevent any precipitation from blowing inside. It works well for rain, but I am concerned about blowing snow. We are in the mountains and the wind direction varies. I’m hoping to make covers out of plexiglass so we can quickly un/install them. Of course I haven’t checked availability or prices of plexiglass since the pandemic started, so that might be a long term goal.
