Morning dhuffjr:It is more like a pool enclosure, the top is screen also. This pic shows it a little better.I wanted to make sure the smoke had some place to go and it really hasn't been a problem very often, but on evenings like this I wish there was a cover of some sort. Still trying to figure out what may work best for that. I do have an EZ-up, but don't really feel like putting it up. Like I said it wasn't a hard rain, just steady and as it comes through the screening it turns into more of a fine mist.Have a GREAT day! Jay
