Is there a smaller projector out there?

Ours is just a deck someone enclosed and enclosed very poorly. Cheap huge windows and and cheap flooring. So essentially an icebox in the winter. I plastic wrapped the windows last year and it was such a pain in the ass -- i never plan to do that again.

Oh wow I have this exact problem. I did spray foam and insulated as much as I possibly could. Frankly, I didn't feel much difference. The best thing i've done is I bought a thick curtain and hung it in the entry to try and isolate the cold to the sunroom.

Keeping an eye on this thread for any solutions too!
