How can I insulate my rented attic bedroom?

Question

I rent, and my bedroom is a large attic conversion. It's very energy inefficient—I can feel heat loss through the ceiling even on a cool summer night. How can I make it more energy efficient without making structural changes that will require my landlord's cooperation? I plan to put weatherstrip around the windows and I'm considering caulking the joists, but the only other thing I can think of is tacking blankets up on the walls and ceiling—a fire hazard, and not very elegant.

Answer 1

I don't think you can just insulate without putting in a vapor barrier and roof ventilation because frost and thaw cycles will occur and soak the underside of the roof and drip down on the insulation etc.

Answer 2

Hi, check out encapsulated insulation batts, it's insulation that is in a plastic type blanket. If you have knee walls and attic access, just staple it between the joists. When you move you might take it with you too! Another solution might be blue board, its a foam board that you could put up and tape seams making it tight, but it may have to be trimed just for that space and it's best to leave it. If your landlord pays any utitlity you might say you get the material I'll put it in. B
