A projector box is not a bad idea and I'm sure you'll do it right based on your results so far. I'm not sure that I would leave the projector out during our winter months though. How ever you do it, I would suggest using a Chief Mount that has a custom bracket. The bracket mounts to the projector and then the projector/bracket assembly attaches to the mount with 4-6 thumb screws. It makes it more or less a quick mount/dismount if you want to take it down and the pitch, roll, yaw settings for the projector stay intact.
And then there is always the retractable roof option!
Sounds like you're having fun! Are you watching any movies?
Watching movies? Ain't nobody got time for that! Lol.
I think that retractable roof's R-rating for insulation is probably like paper, and would probably collapse under snow load, lol.
Given we live in a colder climate, I'm trying to figure out how to use this area more year round, and perhaps still be convertible to an "outdoor" seating area when the temperature is right (which is not as often as when it's wrong, lol).
Yep, I've used Chief before, I actually have an RPA-U on NTP hanging in the basement, with my Sim2 and UH480 lens on the attachment plate just waiting to be hung/thumb screwed on. I'll definitely use similar infrastructure for this outdoor area, and just hang the projector when it's going to be used.
One thing about having an outdoor theater, heated environment, is potentially it could see a lot of use - with my parents getting older, I don't like them having to walk up and downstairs when they visit - this one is just walk out into the covered/heated patio for night time viewing.
How Carl's place holds up in the winter we will only see, sun does come in CLE but not often in the winter, and there's quite a bit of snow. If the bungees/screen don't last, it's an OK investment to me to have to replace it every couple years.
I wonder if the screen is permanently stretched now or if it went back to the normal size, lol - I already moved the pipes (not as easy as it should be), so I bet I'll be super stretching it next time I put it up and it'll cause more issues.
My idea is maybe not the projector box, but using Edmund Optics glass in front of the projector lens, with the projector fully "indoors". The room might have picture windows all around to be able to see the projected image, but the projector itself will look through Edmund Optics glass which probably has no insulation rating either, so it will be like a baseball sized hole for cold air to come through probably during the times I'm trying to use the projector. If they make very thick/some R-value worthy edmund optics type non reflective 99.X% transmissive glass, perhaps I could use that.
