Reply #90: Does your country have tax credits for energy saving home improvements like new windows?

IMO that would be worth checking into. If could you tack or duct tape plastic sheeting over the screens? My Gram wraps plastic sheeting that is cut with a bit extra to wrap the around the frame of the screen and tape it down, and puts it back in the window frame.

If any windows are leaky check out weather stripping. Where I live I can get simple and inexpensive weather stripping that even a diy novice can do as it is self-stick.
