I have been in my house, just over three months and I have enjoyed slowly getting to know it and brainstorming how I can best live in it. My gramma was anxious to help me decorate, but that was the least of my worries. To keep her satisfied, I suggested she look for a couple panels of neutral color thermal-back curtains, plain rods and a couple tension rods. I figured whatever she found, unless the color was so awful, could be used in some fashion.
My second floor is a finished attic space with old windows. After putting plastic on the windows, I decided to hang one thermal curtain. It helps, although when it is 15 degrees out it is hard to feel a big difference. At the stairway going upstairs there had once been a door, but it was probably removed because when open, it would create an awkwardness in the hallway where the bathroom, bedroom and linen closet doors meet. To help, keep heat from rising through that stairway, I used a tension rod and panel to serve as door. It seems to be working well with no draft of cold air in the hall or vacuum of warm air being pulled up the stairs.
