At college I live at this huge house on the 3rd floor. We keep the heat low, but high enough to keep the pipes from freezing. We all have space heaters, but being on the third floor my room gets especially cold. I need some suggestions on how to temporarily insulate my room. Last winter I only covered the windows with the plastic wrap things from Home Depot to stop any drafts that come in, but I think I need something more. I was thinking of creating some insulation panels to place on the walls that lead to the exterior of the house. After googling I didn't find too many resources, but I think I have 2 options. One, would be to get your traditional polystyrene insulation panels and cut them in to square panels and cover them in fabric, then put them on the wall. The other thing I found was this; http://www.jasonmorrison.net/content/2008/project-warm-up-a-room-with-an-insulating-wall-hanging/ Which the guy made a frame from wood, covered one side with fabric and the other with aluminized mylar. I don't know which one would work better. What do you guys think? The first option would be a less construction and less weight on the walls. I would also like to hear some ideas of how to get it on my wall with out nails or screws. Any suggestions and would be appreciated.
