Sounds like cold weather capable to me?????
The biggest culprit has to be the floor. The skirt looks good for someone who is going to move around during the cold weather. I intend to stay in one place so if I decide to camp during the winter I probably will go for a less portable solution. The hard part is to make something functional but not tacky looking. Plywood faced styrofoam might work but that is a lot of cutting and fitting. Also, where do you store them when not in use? A mostly natural alternative would be hay bales wrapped in that white home wrap. There are also a number of different types of fibreglass and foam insulation panels. These are used on the interior of ships hulls and in metal buildings.
While I have winter camped and even taken arctic survival training in temperatures, not including wind chill, of -40F, I like my warmth. My wife demands it so I will be coming up with some sort of solution or my main source of warmth after lights out may stay athome
