Ya lots of windows make it tough. Ceiling insulation might help but with the windows at a r2 or 3 you are in deed fighting a loosing battle. I have a room with lots of windows as well. I added a gas stove that compensates for the windows. I use it when I’m in the room typically. Also if you wanna add new flooring you could consider in floor heat. Good luck!
